Don't Forget about Airless or Air-Assisted Airless Spray Guns


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.

What's new in Graco Pumps? Diagnostics and Cycle Counters on board!

There have been some very smart new additions to Graco's air operated pump line recently. Many of Graco's pumps know offer "Data Trak" as an option; which makes them a kind of "Smart" pump.
Data Trak is an intrinsically safe pump monitoring device that is designed to protect and monitor the pump. It features:
- Easy to set Runaway Control (That actually works dependably)
- Pump diagnostics that advise when to maintain the pump
- Resettable Batch Counter that tracks material usage and maintenance schedule
Data Trak can be used to monitor paint volumes used on a particular job for process control, or to count pump cycles and schedule preventatve maintenance.
Data Trak has been introduced on a number of Graco's Pump Product Platforms such as:
- Merkur Fine Finish Pumps
- Husky 1050 air operated Diaphragm Pumps
- Warm and Hot Melt Pumps
- Hydra Clean Pumps
- Supply Pumps
- Circulation pumps
- NXT Contractor Airless Pumps

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

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

Straight talk on HVLP Spray Guns and Transfer Efficiency.
In 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.

Which Electrostatic Gun? When? Why?
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?

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.

Flat Line Finishing Systems. Not just for the Big Guys anymore.

In our world, a flat line finishing system is an automated process that manufacturers use to apply a finish coating on typically linear or flat stock such as trim, flooring, moldings, paneling or even kitchen cabinet doors. In fact, our partner manufacturer Dubois Equipment Company has used a flat line concept UV Sprayer to finish Pet Cremains Urns. (Of all things).
The advantage of Flat Line Finishing is that the process can tightly control many of the finishing variables and produce high quality finished goods with little labor, little coatings usage or waste and at very high production rates. While it would be common on finish coats to use many of the same types of spray equipment used in manual production lines (Like air spray, HVLP or Air Assisted Airless Guns) a flat line finishing system could use any of the following kinds of coaters:
- Roll Coater
- Curtain Coaters
- Laminators
- X-Y Reciprocators
- Rotary Sprayers
- Vacuum Coaters
- Portable Molding Sprayers (Check out my prior post on the SP-12)
- UV " Mist Coaters"
Proper gun maintenance and cleaning saves money and down time

- DO... Remove air cap if using and HVLP spray gun or air assisted airless spray gun
- DO... Use small brushes or needles to clean all air cap holes
- It's okay to leave air caps and tips submerged in solvent over night
- DON'T... One thing I see a lot, is guns completely submerged in a can or bucket of solvent. This is not recommended practice. By placing the entire gun in solvent you are actually making the gun more dirty as dirty solvent will coat the inside of the air passageways and when it dries you can have paint and dirt flakes come out of those passageways and onto your part. Not Good.
- DON'T... Another thing soaking the entire gun in solvent can do is erode any o-rings in the gun and if using an HVLP spray gun you can ruin the plastic air valve that opens when the trigger is pulled.
- DO... Use small soft bristled brushed or tip cleaning needles to clean or unplug any debris in your airless or air assisted airless spray gun.
- DO... It is okay to clean or wipe down the outside of your gun with solvent.

Graco and Binks HVLP Spray Guns. How do I set them up?
Did you ever wonder just what pressures you were supposed to use when setting up an HVLP (High Volume Low Pressure Spray Gun? In order for the gun to function as it was designed; the setup is actually quite different than when setting up an air spray gun. For purposes of this post we will talk about setting up a pressure feed HVLP Gun (Pressure Cup or Tank); which you would commonly see in more of an industrial application.
The first thing to remember is that while an air spray and HVLP gun may look alike and share many common features; the HVLP gun will not provide the coatings savings and reduced overspray if set up just like an air spray gun.
As a rule; fluid; pressures to the HVLP gun will be significantly lower than those supplied to an air spray gun. The reason for this is that we need to maximize the time the coating is in front of the air cap in order for the HVLP Gun to properly atomize the coating. The HVLP Gun only has so much atomization energy compared to a conventional air spray gun and simple physics will prevent the coating from atomizing properly if the fluid pressure is to high.
To demonstrate; turn the atomization air to the paint gun off. Set your tank pressure to 25 PSI. Watch how far the paint travels when the gun is triggered. Depending on the paint viscosity, I'd bet it would shoot clear to the paint filters. Liken it to if the paint coming out of the gun at 25 MPH. Now readjust the tank regulator so that the pressure is 10 PSI (or 10 MPH.) That lower fluid pressure (slower coating speed) allows the coating to remain in the atomization zone for microseconds longer- giving the HVLP gun a chance to do it's job.
Rule of thumb; again depending on paint viscosity; the coating coming out of the gun should travel straight 6-8" before falling off downwards. (Again- no atomization air) Whatever your gauge says when that distance is achieved is the correct pressure. It would commonly be in the 5-10 PSI range. At that point; add atomization air until you get a well defined and well atomized spray pattern. The newer industrial HVLP guns will commonly need 20-40 PSI or so of atomization air. Again; only the minimum air required to achieve a satisfactory degree of atomization should be used. Any more is wasteful.If you can't keep up with production speeds with the gun setup this way, you gun bump up to the next largest fluid nozzle. Still can't keep up? Consider an Electrostatic or Air Assisted Airless Gun. HVLP guns are great for certain applications but are not a panacea.
When your HVLP spray finishing equipment is properly set up; it will give you a great paint job and provide the desired economic benefits that it is designed to do.

An Electronic Paint Proportioner in a Paint Booth? What will they think of next?
That's right. Computers have actually made it into the Paint Booth. They're everywhere else, so why not in a messy, solvent laden painting environment?
The reason why electronic paint proportioners have made it into the spray booth is because finishers are demanding simple, accurate ways to insure proper mix ratios and are tired of scrap, rework and wasting paint and solvent due to off ratio paint conditions from "hot potting".
Graco's Pro Mix Easy is a simple, inexpensive, intrinsically safe method to provide on ratio paint to a variety of air assisted airless, air spray, HVLP, airless and electrostatic spray guns. The coating resin and catalyst are supplied separately to a gear meter based proportioner and mixed in their proper amounts through a patented integrator and static mixer assembly. Only the mixed paint in the fluid hose must be flushed at the end of the shift.
Graco's patented "Pro" Technology allows the unit to operate in a Class I Division I environment with no need for an external power source. Built in, configurable alarms help avoid any off ratio conditions. Paint and solvent savings as well as a reduction in scrap and rework provide a very quick return on investment.
