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.
