15.
Small amounts of lubricant may be present in the condensate and must be disposed of properly. A wet
(control) air receiver can also perform the moisture removal function provided the compressed air flows
through the receiver. Additional air treatment may be needed for your application to meet the
requirements for higher quality air. Air dryers, filters and receivers are available. Contact the factory for
further information.
2.10
Package Discharge Service Valve
A customer supplied package discharge service valve must be installed immediately following the
compressor assembly or moisture separator (if supplied) and before connection to downstream air
treatment devices, air receiver and compressed air system header. This valve will provide maximum
safety and flexibility for servicing the air compressor. The valve should be a full port design to reduce
pressure loss during operation.
2.11
Air Piping
WARNING
DO NOT use plastic pipe or rubber hose(s) in any part of the main air distribution system.
Doing so may result in serious injury to personnel and damage to equipment.
The maximum recommended CFM free air for schedule 40 steel pipe is tabulated below. This is based on
1/2 PSI pressure drop per 100 feet of pipe at 100 PSIG operating pressure.
Table 3. Maximum CFM for Schedule 40 Pipe.
Care must be taken to avoid placing a strain or bind in the piping when connecting to the compressor.
Flexible connections are strongly recommended when connecting to plant piping to minimize vibration
and avoid piping strain.
CAUTION
Failure to drain moisture away from the compressor may result in damage from contamination
of the lubricant. Contaminated lubricant can damage equipment and failure.
Air piping should be level with or have a drop in elevation at the package outlet in order to drain the
moisture in a tank or moisture separator. See the Compressor assembly drawing for additional
information.
