The important components of the compressed air system are:
-
Inlet Filter: Removes particles from the air entering the compressor.
-
Compressor: Compresses air to a smaller volume, increasing the pressure.
-
Motor: Drives the compressor.
-
Compressor Controller: Directs the compressor’s output. It may be microprocessor, electromechanical or pneumatically based. Advanced controllers include machine protection and information management.
-
Aftercooler: Compression leaves the air hot and wet. The aftercooler lowers the temperature of the air, thus condensing and removing the water.
-
Separator: Removes liquids from the compressed air. These are generally installed in compressor after the aftercooler.
-
Receiver: Stores a large reserve of compressed air to maintain a smooth flow to the plant.
-
Air line Filter: Removes solids and liquids from the compressed air stream. Filters can be placed throughout the system.
-
Dryer: Helps to eliminate any remaining moisture in the compressed air by using either a refrigerated condenser or a desiccant. Refrigerated condensers cool the air to condense water vapor into a liquid that is then drained from the system. Desiccants are powders or gels that remove water by absorbing it.
-
Condensate Trap: Collects and discharges liquid that condenses out of the air stream. Integral part of after coolers, dryers and separators
-
Distribution Piping: Links the components. It distributes the air from a main header to branch lines and sub headers to drop points connected to individual tools.
-
Pressure regulator: Controls air pressure and flow at individual points of use.
