Building Pneumatic Control Air
Building pneumatic control air, is supplied by a compressor, which provides the required 20 psi signal for the building pneumatic temperature controls.
This type of system still exists in many of today's older buildings, but is being phased out. Air compressor control though is still a function of many buildings operations.
Explain Compressor Components
This information will consist of:
Compressor:
The compressor provides high pressure air to the receiver tank. The receiver tank is equipped with pressure sensing controls which control the compressor operation.
Receiver tank:
The receiver tank holds the compressed air under pressure. The compressor operates to maintain this air at a given preset pressure. It provides capacity for the system.
Oil Filter Station:
The filter station removes oil from the compressed air, which is supplied to the building controls. Oil in the compressed air will cause problems for the controls.
Refrigerated After Drier:
The refrigerated after drier removes moisture from the compressed air. Moisture in the compressed air will cause problems with the controls.
Pressure Reducing Station:
The pressure reducing station allows the high pressure compressed air to be reduced to that level as required by the building pneumatic controls. This pressure should be a little higher, than required to compensate for losses in the system.
