You don’t hear much about air compressors but they are an indispensable part of air duct cleaning.  You need an air compressor to do air washing, air whipping, and run pneumatic tools.  Air washing and air whipping are a primary cleaning method for many contractors.  To maximize their effectiveness and work properly air washing/whipping tools consume lots of air and that’s where the air compressor comes in.  To maximize your productivity, you don’t want to stop working while you wait for your air compressor to catch up.  Let’s look at the following air compressor features:

  • PSI = pounds per square inch of air.  This means the force of the air being delivered to the air washing or air whipping tool.  More is better.
  • CFM = cubic feet per minute of air.  This means the volume of the air being delivered to the air washing or air whipping tool.  More is better.
  • Receiver tank is a holding tank for the air that pumps creates.  20 -30 gallon sizes are found on most systems and 60-80 gallons tanks are found on the big truck units.
  • Receiver tank certification.  An ASME certified receiver tank means that that tank was taken off the production line and individually tested to verify it meets pressure vessel safety standards.  Not all tanks are certified which could be a safety issue and a possible violation of OSHA standards.
  • Inline water filter is an option that takes the moisture out of the air before it goes to the air wash/whipping tool and pneumatic tools.  It’s important to keep moisture out of pneumatic tools so the internal components don’t rust.
  • Dual air line hook-up is an option that allows you to use two air lines on the job.  Usually found on units with a minimum of 175 PSI/16 CFM of air.
  • Gas vs electric – gas units sit outside while electric units can be used indoors.  Residential projects can use either gas or electric units while commercial projects tend to use more electric units.  
  • Typical potable systems
    • 1.5 hp electric air compressor generates 140 to 150 PSI and 6-8 CFM of air, 9 gallon (two 4.5 gallon) or 20 gallon tank, requires a 110 volt/60 Hz/20 amp circuit.
    • 5 hp electric air compressor generates up to 175 PSI and 17 CFM of air, 20 gallon tank, requires a 220volt/60 Hz/30 amp circuit.
    • 9hp gas air compressor generates up to 175 PSI and 19 CFM of air, 20 gallon tank.
  • Typical mounted system
    • 13hp gas air compressor generates up to 200 PSI and 23 CFM of air, 30 gallon tank.    
  • Typical packaged system (uses a gas engine to power both the fan and the compressor)
    • Generates up to 175 PSI and 23 CFM of air, 30 gallon tank.  
  • Typical big truck packaged system (uses a gas engine to power both the fan and the compressor)
    • Generates up to 200 PSI and 36 CFM of air, 60 gallon tank.
