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
