| 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. |
