Inlet Expansion Joint
Cooper Turbocompressor recommends the use of the Inlet Expansion Joint option (which consists of a
rubber sleeve with stainless steel clamps) as a means of joining the inlet air pipe to the compressor.
(See Figure A—5.) When making this connection, do not use pipe smaller than the recommended pipe
size; larger pipe is in fact preferable, since the increased volume will reduce both noise and pressure
loss.
Inlet Air Startup Screen
The inlet piping must be designed to prevent any solids from entering the compressor inlet. When long
runs of inlet piping are required, or when visual/physical inspection of the finished piping is difficult,
the temporary conical Inlet Air Startup Screen option serves to filter substances from the intake air
supply before they can reach the compressor and damage internal components. In such instances, it is
important to locate the screen as close as possible to the compressor inlet. The Inlet Air Startup Screen
is shown in Figure A—6.

CAUTION:
Be certain to remove the Inlet Air Startup Screen after approximately 40-50 hours of
compressor operation. If it is not removed, the pressure loss across the screen can significantly
reduce overall compressor performance.

Inlet Filter/Silencer
The Inlet Filter/Silencer option will remove airborne particles that would otherwise erode aerodynamic
components, foul heat exchangers and tend to accumulate within the air flow passages. The silencer
feature of this component will reduce compressor noise that travels through the inlet air piping. The
inlet filter/silencer is a permanently installed component.
