 Airless & Air-Assisted Airlesss Spray Guns
I walked in to a potential customer of mine last week who welds and paints large steel parts. He happens to be spraying them with HVLP Guns and a pressure tank system. In my humble opinion; anyone who has to coat large parts where a car like finish isn't required should be using high pressure spray guns (i.e. Air Assisted or Airless Guns).


Back to the Basics

In some of our past blogs we've talked about the different spraying technologies. Air-spray, HVLP, Airless or Air Assisted Airless. If you recall, Air Spray and HVLP both use large amounts of air pressure to atomize the paint.  With Airless/Air-Assisted Airless technology we are using High Fluid Pressure (500-2000psi and above) and a very small tip to atomize the coating.  Airless and AA Guns are by nature much more efficient than Air Spray or HVLP technologies because the coatings aren't blown around by large amounts of air and have a better chance to get to the part.  

In perfect spraying environments, Air Spray Guns can be up to 25% efficient (this means 75% of the paint that comes out of the gun goes into the filters, on the floor or walls or on your painter!!). HVLP guns are a little better, in the 35-45% range and Airless/Air-Assisted are the most efficient, in the 50-60% range.

Airless Spray Guns:

Airless Guns use high pressure fluid and an airless tip with a thousandths of an inch hole in to atomize the coatings.  This is a very efficient way to paint, but the quality of finish isn't the best. This technology is used a lot in industrial/farm equipment, outdoor items like water towers or wind turbines or structural steel.

Air-Assisted Airless Guns:

Like Airless Guns; we are using high fluid pressure and small tip to atomize the coating, but also using a small amount of air to help even out the fan pattern and provide a better finish than airless. We see and recommend this technology for parts that the finish quality is more important than a cattle finish but not as high as a car.  These guns are used a lot in the wood industry, large industrial equipment and school buses to name a few.  A good example of the kind of parts I'm talking about is Bryan Steam, who use AA guns to coat their large steam boilers.


Back to the case of the potential customer I talked about at the beginning.  When I walk in somewhere and see someone using an HVLP or Air Spray Gun to coat a large part that doesn't require a Class A automotive finish, I wonder why they're not taking advantage of Airless or Air-Assisted Airless technologies.

Remember; if you're putting more paint on the part with each pass, you're not only saving $$ on coating costs but you should also be able to paint faster and save on things like booth filters.

Ultrasonic cleaners used in spray gun clean up

Wednesday, January 6, 2010 by Kent Garrison
Crest Powersonic, Ultrasonic Cleaner, Spray Gun Cleaner, Gun Cleaner, Paint Cleanup


Cleaning low or high pressure spray guns, pressure tanks systems, paint pumps or any spray finishing equipment has always been a burden to the paint industry; until now.

Crest Powersonic (Ultrasonic) benchtop spray gun cleaner is a device that uses waves of acoustic energy (a process known as "cavitation") to loosen and break up debris on instruments.  When ultrasonic energy is introduced to a cleaning solution, the foundation of ultrasonic cleaning occurs.  Ultrasonic energy causes alternating patterns of low and high pressure phases. During the low pressure phases, bubbles or vacum cavities form.  In the subsequent phases these bubbles implode violently.  That process is called "cavitation".

Cavitation provides an extreme scrubbing action that leads to unprecedented cleaning time and consistency when compared with simple soaking part in solvent and brushing.  The bubbles caused during the cavitation are so small they can penetrate mircoscopic crevices, including those found in cured paint.  As a result, ultrasonic cleaning is one of the most highly effective and efficient methods you can use for cleaning your spray finishing equipment. 

Crest Powersonic cleaners come in a variety of sizes and include automatic timers and heaters and range in price from $1000 to $2000.  Click here to download a brochure on these units.  Also see us for an environmentally friendly (Read that GREENCleaner that make these units super efficient at removing even the most stubbornly cured paints and 2K urethanes.

  Please call or email if you have any questions or would like to purchase an ultrasonic cleaner. 800-823-7527

Looking for a Spray Booth in Indiana? Or at least someone who knows something about them?

Monday, December 28, 2009 by David Garrison

Elliott Equipment has been selling Spray Booths in Indiana since 1947. You may find a number of internet sites that will be more than happy to collect your money for a paint spray booth but none of these sites have salesmen who will take the time to visit your facility, make an assessment of your specific requirements and make a recommendation based on your needs.

Sure; spray booths are simple aren't they? Just a bunch of punched and flanged panels with some filters, a motor and some ductwork. To avoid being dissatisfied with your purchase; consider the following:

1. What is your part size? Do you know the recommended booth dimensions for a part of your size? An incorrectly sized paint spray booth will not give the sprayer the room to manuever his spray gun appropriately and this may lead to defects on the sprayed part.

2. Have you considered whether replacement (Makeup) air will be needed? Never even heard of such a thing? Spray booths must move at least 100 LF per minute across the operator in order to be considered code compliant. Multiply that 100 by the height and width of the boot you are considering. Turns out to be a pretty big number doesn't it? Now compare that to the cubic dimensions of the room you want to install the spray booth in. Most folks have no idea a paint spray booth will remove that volume of air.  This can have important implications on spray booth efficiency, performance and importantly: operator and plant safety. Another reason to have a professional assess your requirements and make a specific recommendation based on your needs.

3. Have you considered your Indiana Environmental permitting responsibilities? Didn't even know you had any such responsibilities? You mean there might be fines if I don't comply?

4.  I could go on an on. You mean freight is extra? No control panel included? Motor voltage isn't right for me? What do you mean stack isn't included? (And by the way- I didn't know it needed to be 6' above the roof line). Shouldn't vent towards a parking lot? Why not?

Let us point you in the right direct there as well as answer any important question you might have. This is too important a decision to your manufacturing process to leave to an anonymous website who may well not have your best interests in mind.

Give us a call at 800-823-7527. We'd be happy to make a no obligation consultation to help you out . Or send a note to david.garrison@elliottequipment.com

The Co$t of Compressed Air in a Spray Finishing or Powder Coating System

Wednesday, December 2, 2009 by Kent Garrison

Compressed Air, Finishing Systems, Powder Coating Systems, Spray Guns, HVLP Spray Guns, Compressed Air Cost
How Much $$$ is your compressed air system costing you?
 
What can you do to control that cost?
 
Your compressed air system is the most inefficient piece of equipment in your Powder Coating System or Paint Spray Operation.

Some big consumers of compressed air in powder coating systems and paint systems are:
 
  • Paint Mixers
  • Air Operated Pumps
  • Air Spray Guns
  • Fluidized Powder Hoppers
  • Cartridge Style Powder Coat Spray Booths
  • Powder Spray Guns
Here is a simple formula to determine the cost of your compressed air:

(full load amps) x (voltage) x (1.732) x PF x hours x rate
------------------------------------------------------------------------
  1000
 
Full Load Amps = average of three phases
Voltage= line to line voltage
PF= power factor
Hours= annual hours of operation
Rate= electricity cost in $/kilowatt-hours (kWh)



Some things to consider when trying to cut down on compressed air costs:
 
  • Swith standard air spray guns to HVLP Guns or better (electrostatic spray gun)
  • Use only enough air to properly atomize your coating and no more
  • Consider changing air motor on your paint mixers and agitators to a piston style motor. This can cut air consumption in half.
  • Regularly check lines for leaks

Spray painting difficult parts. Here's some help.

Monday, November 9, 2009 by David Garrison

We often get calls from customers looking for help in spraying parts with difficult geometries. Long tubular parts, parts with blind corners and interior parts with small openings can successfuly be coated with Binks Spray Gun Extensions.


Last week a customer called wanting to coat an ammunition box that had deep recesses and was difficult to coat with conventional paint spray equipment or high pressure spray guns. Lots of overspray, and poor finish quality created a finishing headache for him.


                                                                                       
We were able to the offer the customer a Binks 12" HVLP Extension that he could use with a traditional Mach1 HVLP gun which solved his problem. He also purchased an extension for his existing Binks 2001 gun that had a 45 degree angle head that give him greater control and flexibilty when finishing other difficult parts.

Air Replacement for your Finishing Spray Booth

Thursday, October 29, 2009 by Kent Garrison
Air Make Up, Global Finishing Sytems, Global Spray Booths, Spray Booth Air Make Up
 
When it's time to purchase a finishing spray booth, a lot of people don't think about an air make up unit.  What is is "Air Make Up or Replacement", and what do they do?

The main goal of an Air Make Replacement Unit is to replace the air that you are exhausting through your spray booth.  For example: If you have a 10x10 spray finishing booth you are exhausting approximately 10,000 cubic feet of air per minute from your building.  Lets say you are in a 50,000 sq ft building; you are going to become negative very fast, making it hard to open doors, bring your building to outside temps very fast (bad in winter) and make your spray booth ineffective.  Here are a few things an AMU does:
 
  • Eliminate problems with drafts, contaminated air and tempature control

  • Creates balanced building pressure and maintain proper comfort levels

  • 100% Fresh Air

  • Add a bake or cure cycle to your spray finishing process
These units can be gas fired or electric, can be mounted on your building roof, spray booth roof or outside your building and ducted in.

I mentioned earlier that without an air make up unit your spray booth could become ineffective.  What can happen is called "fan cavitation".  This means your spray finishing booth  fan will spin but with no air to move it will not accomplish its goal of exhausting spray fumes out of the building. You can see where that could become a big problem fast.

This was just a brief introduction to Air Make Up/Replacement Units; if you'd like to learn more, click here for a detailed brochure.

You can also call me at 800-823-7527 for any questions about finishing spray booths, air make up units or any of your paint spray equipment needs.

 

Binks invents the first industrial paint spray gun. in 1890!!!

Monday, October 26, 2009 by David Garrison

I had an inquiry the other day from a customer who wanted to know who invented the paint spray gun. He was writing an article for his hobby club and needed background information on paint spray gun equipment. I thought this information might be of interest to the general public so I have included it here on my blog.

As is so happens, Binks Manufacturing; now a subsidiary of ITW and manufacturer of the famous Binks Spray Gun line claims credit for inventing the paint spray gun.

 
In 1890, Joe Binks; an employee at Marshall Fields Department Store invented a sprayer to whitewash the massive basements of the store. His home made invention remained obscure until 1893 when Chicago hosted the massive 1893 Columbian Exposition;  the last and best of the 19th Century World's Fairs. With only days left until the opening, 90% of the buildings were still unpainted. It was Joe Binks' golden opportunity to demonstrate his sprayer and by opening day, all the buildings were a gleaming white.
The "White City" as the fair was known, opened on time, thanks to the Binks Sprayer. He later founded the Star Brass Works, later changed to Binks Mfg. Co., that would become one of the premier manufacturers of industrial and commercial spray paint gun equipment.
 





So there you have it; some trivia to impress your friends and co-workers. If you'd like to see what is available in today's modern world of Binks Spray Guns and fluid handling products:

They are using the new Nordson Encore Gun. The Encore Gun System is one of the most advanced new powder coating systems on the market today.  Here are a few features that help PACE get the finish they are looking for.
 
Nordson Powder Coat Gun, Nordson Encore Unit, Powder Coating Indiana, Nordson Indianapolis, Nordson Indiana
  • True "on gun controls" allow the user to change powder flow or recipes without leaving the booth, while spraying.  The ever popular purge air is incorporated on the gun as well, allowing a blast of air to clear the gun of excess powder.

  • The new Encore Pump is a step up from standard powder coating pump.  It is the most efficient pump on the market and maximizes transfer efficiency by getting more powder to the gun using less air.

  • First pass coverage and gun to part distance make this gun unique.  Because of the efficient Encore pump, user can get the gun right on the part like never before. A combination of Nordson's patented "Automatic Feedback Control" and the maximum powder delivery to gun allow for this close gun to part distance.  This feature makes it a lot easier to coat the dreaded "Faraday Cage" areas.

  • Last but not least, the Encore unit features a brilliant on screen LED display.  The user can control Powder Flow, Gun Air, KV or MicroAmp settings.  There are also 20 user set recipes allowing you to save settings for each part you coat.  Nordson also has 3 preset modes: Re-Coat, Metallic and Recessed Box.

What's the latest in Paint Spray Gun Equipment? Get the scoop here.

Thursday, October 1, 2009 by David Garrison


Nitrotherm SprayIn the past few years an Italian company has been marketing a process that I think has some legs. It's not a new type of spray finishing gun; rather an enhancement to the spray finishing process that can have some significant benefits in terms of paint savings, finish quality and dry times. The process is called NitrothermSpray and it is making inroads into automotive, wood and aerospace applications by delivering some pretty substantial benefits.

NitrothermSpray can be used with several different types of spray finishing equipment. Air Spray guns, HVLP Spray Guns, Electrostatic Spray guns and and Air Assisted Airless Spray guns are all easily adapted to this new technology.

The heart of the technology is the Nitrogen Generator. Your existing spray gun is attached up to the Nitrogen Outlet instead of a traditional compressed air outlet.
 


 

The process briefly is this: 

1. Nitrogen is extracted from the compressed air.  Nitrogen is Inert and Anhydrous which means that the finish will be much more consistent using Nitrogen. Customers are seeing dramatic reductions in dirt and moisture problems related to the use of compressed air.

2. Ionization of the Nitrogen creates a positive charge that attracts the paint to the surface that is being painted.  This results in less overspray and a higher transfer efficiency rate.

3. A Heated Hose is used for viscosity reduction and control and reduces or eliminates the need for solvents which reduces VOC's and creates a Greener Environment.  This helps to make significant improvements in dry times and time to re-coat which leads to improved productivity

How do I properly size my Finishing Spray Booth?

Monday, September 28, 2009 by Kent Garrison
If you are thinking of purchasing a finishing spray booth or powder coat spray booth there are a few things to keep in mind.  The most important thing to think about is the size of your spray booth. You don't want to under-size a booth and have to come back and modify at a later date (time and $$).

The painter needs room to work around his part.  Spray booth size is critical to the success of the painter and his spray finishing equipment.  Here are some factors to consider when you are sizing your booth:

  • WIDTH: Measure the width of your largest part then add a minimum of 2.5 feet to each side to give you painter adequate room to move around the part.

  • HEIGHT: The height of you spray booth should be two to three feet above the largest part you plan to paint.

  • DEPTH: Working depth should be enough to fit your largest part completely in the spray booth plus at least 3ft at the rear (filters) for clearance.

Straight talk on HVLP Spray Guns and Transfer Efficiency.

Monday, September 21, 2009 by David Garrison

Devilbiss Compact HVLP Spray GunIn a post last week on Electrostatic Spray Guns, you may have seen my comment about the transfer efficiency of HVLP Guns being in the 20-20% range. Kind of a provocative statement, wouldn't you say? Here is how I would defend that statement.

Since HVLP guns were mandated for most finishing operations in California by the South Coast Air Quality Management District (SCAQMD) a number of years ago; most other states environemtal governing bodies have implemented similar regulations and the transfer efficiency number of 65% has been generally accepted.

The problem is; finishers are fooling themselves if they think they are really achieving that high a degree of efficiency; and are hurting themselves (and their bottom line) if they are using anywhere near that number when calculating their actual applied coating costs.
  • When the tests were done many years ago that deemed HVLP Spray Guns 65% transfer efficient; one must look closely at the criteria used. Virtually any type spray gun can have an artificially high transfer efficiency rate if the test criteria are favorable enough. Consider this: if one were to use as a test substrate a 4' by 8' sheet and limit the coating viscosity and flow rate enough; with no criteria for finish quality; one can achieve virtually any transfer efficiency one desires. I am afraid that was the case when these test were done. There were no universally accepted standards used that would have allowed the test results to have universal significance under actual factory conditions. In other words; had the test substrate been 1" tubular weldments; would one expect to still see 65% transfer efficiency? That is the problem with the tests and the reason the 65% transfer efficiency claim should be viewed cautiously.

  • In real world practice; HVLP guns began to be used in applications where their limitations became glaringly evident. When coating viscosity's exceeded certain ranges, or when production rates were high; HVLP guns simply could not offer acceptable atomization characteristics. At that point finishers began to try to operate the guns outside the relatively narrow range of their physical limitations and the guns became nothing more than a very expensive conventional air spray gun,. It's a simple matter of physics; when we lower the atomizing air pressure (one aspect of atomizing energy)  of a spray gun enough; even if we keep the atomizing air volume high (another aspect of atomizing energy); we quickly reach a point where there simply isn't enough physical energy available to atomize the coating satisfactorily. either the finish quality or the production rate will suffer.

Our experience has shown that HVLP Guns are a good choice on lighter viscosity coatings or where production speeds are low to moderate.  Air Assisted Airless Spray Guns are most suitable for wood products clearcoats (sealers, lacquers, paints, varnishes) and other industrial finishes where good quality atomization (Not Class A Automotive) and higher production speeds are required. Electrostatic Spray Guns-both Conventional and Air Assisted Airless will also have production speed and atomization advantages over HVLP Guns in many applications.


Now; nothing I have said in this post should be construed as telling finishers to ditch their HVLP guns. On the contrary; EPA rules are EPA rules and substantial fines can be imposed upon finishers if the equipment they use is deemed to be non-compliant. The point of this blog is more to have users of spray guns carefully consider whether HVLP guns are their best choice or perhaps have them consider one of the other compliant technologies such as Air Assisted Airless (which also have HVLP Air Caps) or Electrostatic Spray Guns.

Economical powder coating system from Nordson

Saturday, September 19, 2009 by Kent Garrison
Nordson Vantage System, Vantage Unit, Nordson Powder Coating, Nordson Vantage
In the past we've talked about some of Nordson's more advanced powder coating equipment. Today we'll learn about a more economical, easy to use powder coating system.

This unit is called The Vantage Unit. This system uses some of Nordson tried and true technologies; such as Automatic Feedback Current, but doesn't offer a lot of the extra features that you find in the Prodigy and Encore powder coating systems.

Automatic Feedback Current or AFC allows users to set the gun current at a level that will provide optimal (not necessarily maximum) charge and field strength for each application
. Control of the gun current ensures that the number of ions generated in the charge zone is sufficient to charge the coating effectively, but not high enough to create excessive free-ion current on the already-deposited coating layer.

This system is about as easy to use as you can get. I set up a Vantage last week with a customer in Lafayette, Indiana. It took about 10 minutes from the time I walked in door until to the time we started spraying.  

The only variables the user has to control are:
  • Gun Atomizing Air
  • Powder Flow Air
  • KV or AFC Setting

You can't get much easier than that.  The Vantage is available in the standard vibratory box feed or 50lb hopper unit, and can be purchased on our online sales site for a great price.

When selecting a Finishing Spray Booth there are a few things to keep in mind.  Whether you're looking for a liquid finishing spray booth or powder coat spray booth there are many styles and technologies to choose from. Let's look at a few:





 
 
                                
LIQUID SPRAY BOOTHS
 
  • Standard CROSS DRAFT finishing spray booth.  A cross draft booth like the on pictured above is named so for the way air enters the booth. In this case, air is drawn in front open face, through the filter plenum and out the exhaust stack. One drawback of a cross draft is that the operator has to always spray towards the filters. If he/she were to stand with his back to the filters and spray, he/she would end of painting themselves as that is the direction the air is moving.

  •  DOWNDRAFT spray booths are another example of spray finishing booths.  In a Down Draft booth, air is either forced in or drawn through a filter plenum on top of the booth and exhausted through a pit in the floor.  This is the most efficient spray booth on the market and allows the operator to spray facing in any direction he desires.

  • A SIDE DOWNDRAFT similar to a downdraft because the air is coming from the top of the booth and moving down. The similarities end there as the air is then exhausted through a plenum running along the bottom side walls of the booth. This is more efficient than a cross draft but less than a true downdraft.


POWDER COAT SPRAY BOOTHS
 
  • CARTRIDGE STYLE style powder coat spray booths draw air in through an open face or filtered door and move through large cartridge style filters that are set to pulse every few minutes. These pulses help discharge built up powder to ensure free air flow.

  • 3 STAGE FILTER BOOTH: This is like a standard liquid finishing spray booth except that instead of a single filter it incorporates a three stage system. These booths also do not exhaust to atmosphere, the air is thoroughly cleaned through the 3-stage filtration and recycled back into the plant.

Which Electrostatic Gun? When? Why?

Thursday, September 17, 2009 by David Garrison
Graco Pro XS Air SpraSpray Guny Electrostatic We get many inquiries asking for electrostatic spray guns and most of the time the caller is looking for a recommendation on whether it should be an air spray or air assisted airless electrostatic gun. For this post we will focus on liguid electrostatic spray guns; not powder spray guns.

I start out by asking a number of questions to help me make a recommendation. 



  • What is the part you are painting? Size, Geometry, Complexity?
  • What is it made out of? Metal, Plastic, Wood?
  • What is your finish quality criteria? "Class A" Automotive?, Industrial? Just trying to cover the imperfections?
  • What is most important? Finish Quality? Speed? Transfer Efficiency and Paint saving?
  • Are the parts conveyorized or  too large for a spray booth?
  • Are you trying to finish on site or outdoors?
  • Is the coating solvent or waterbased?
  • How much is the coating per gallon.? How much do you use a day, week, month, year?
  • Really still want to use an air spray gun but the environmental inspector says it has to be electrostatic?
The answer to these questions will help me make a recommendation on the best spray technology for their application. One size definitely does not fit all when it comes to electrostatics. 

Then I try to clear up some misconceptions about the nature of spraying paint electrostatically. I can tell you the number of folks who have the idea that (1) electrostatics will completely eliminate overspray or (2) somehow "bond" the paint to the substrate better. Neither of these truisms is true.

(1) Depending on the technology chosen and the answer to; the questions above we might reach transfer efficiencies in the 40%-75% range. (Actually there is a gun used to refinish metal furniture onsite that will achieve efficiencies in the 90% range; but that is a topic for another post and not pertinent to our discussion here) Even with those transfer efficiency ranges, you can see that these guns will still produce overspray. Given; however; that conventional air spray or even air asisted airless or HVLP guns will have efficiencies in the 20-30% range these are significant improvements that we are talking about and these paint savings and productivity increases can easily pay for the cost of one of these guns in a short period of time. from then on the savings go directly to the bottom line.

(HVLP guns with a transfer efficiency of 20-30%? What about the 65% you always hear about? Check back in the near future for a post with straight talk on the real transfer efficiency of an HVLP gun.)

(2)
 While it is true that paint; as it is sprayed will be electrostatically attracted to the substrate; once the negatively charged paint is deposited on the part; the electrostatic charge is disipated and the paint sticks or "bonds" to the part in the same manner as if it had been painted conventionally.
