Tech Tips: Helpful Hints

If this section doesn't quite address what you want to know, feel free to email us or call us at any of our three, convenient locations for assistance. Our expert staff and technicians welcome the opportunity to help you keep your system operating at peak performance.

The following is a good start for basic maintenance of your air compressor.

  • Pressure/Flow – Pressure (psi) and flow (cfm) are inversely proportional. As pressure goes up, air flow goes down.
  • CFM – 5 CFM per horsepower on a 100 psi air compressor
  • Pressure Drop – Each psi pressure drop equals 0.5% in horsepower.
  • Piping – Bypass piping and valving on compressed air system components (dryer, filter, drop legs, etc.) allows periodic inspection, maintenance and repair without interrupting air supply to the complete system.
  • Heat Load – The heat load on an air-cooled compressor is hp x 2545 BTU/hour.
  • Dryers – 65 percent of condensate is removed by the aftercooler; 96 percent can be removed by a refrigerated dryer.
  • Moisture – Every 10-degree increase in discharge temperature doubles moisture content.
  • Slope – Slope main lines about 1.16" per foot away from the air compressor. Install drop legs for condensate removal.
  • Pneumatic Tools – If a pneumatic tool immediately slows down when trigger is pulled, check fittings to ensure there is not a restriction in air flow.
  • Air Supply Shut Off – Before making or breaking any air connection, always turn off air supply. Use a ball valve to turn off the air supply. Never kink a hose as a shortcut - you could damage or even rupture the air hose.
  • Air Hoses – Protect air hoses from damage - move them out of the way of vehicles so they are not run over. Be sure not to drag hoses or expose them to sharp corners.
