What it means |
| |
|
| Aftercoolers |
Designed to reduce the temperature and liquefy condensate vapors |
| |
|
| Check Valve |
A device that allows fluid or air to flow in only one direction. |
| |
|
| Cubic Feet Per Minute (CFM) |
The volume of air that is able to pass through an opening in one minute. |
| |
|
| Dryer |
Compressor tanks are made of steel, when water gets into the tank,
the tank can rust thus reducing the life of the compressor. A dryer dries the air
in the tank, reducing the amount of water collected |
| |
|
| Dual Stage |
Compressors where air is compressed from initial pressure to an intermediate
pressure in one or more cylinders |
| |
|
| Filter housing |
Cover which protects the filter assembly |
| |
|
| Kick-in Pressure |
Factory set low pressure point of the pressure switch that starts the
compressor to re-pressurize the tank to a higher pressure |
| |
|
| Kick-out Pressure |
Factory set high pressure point of the pressure switch that stops the
compressor from increasing the pressure in the tank above a certain level |
| |
|
| Low oil shutoff |
A feature which shuts off the engine if it runs low on oil, preventing
damage or failure. |
| |
|
| Oil free compressor |
Air compressor that has no oil inserted into the compression chamber
for lubrication, cooling or sealing. Typically used in the medical and food processing
field |
| |
|
| Pneumatic |
Related to the movement of air |
| |
|
| Pneumatic power |
Compressed air power |
| |
|
| Pounds Per Square Inch (PSI) |
A unit of measurement referring to the pressure applied on one square
inch of an object's surface. |
| |
|
| Pressure Switch |
An instrument which senses a change in pressure and automatically adds
or decreases air in the tank. |
| |
|
| Purging |
The elimination of undesired gas or liquid from a system. |
| |
|
| Reciprocating Compressor |
A reciprocating compressor uses pistons driven by a crankshaft to deliver
air at high pressure |
| |
|
| Rotary Screw Compressor |
A compressor which utilizes two intermeshing helical rotors to trap
a volume of air, then compress it to a higher pressure. Rotary screw compressors can
be run at lower temperatures for 24 hours per day, 365 days a year. |
| |
|
| Safety valve |
A valve which limits fluid pressure by releasing some of the pressurized
liquid or gas |
| |
|
| Single Stage |
A compressor in which the air is compressed from initial pressure to
final pressure in one step. |
