PIPING
General
As CMH Series compressors are comprised of two modules (compressor and separator), there is
necessarily interconnecting piping between the two. These hoses are not provided with the units, as the
required lengths of the hoses are dependent on the relative location of the two modules in their installed
location. It is left to the installer to obtain hoses of the correct type and length for each installation.
The following hoses will be needed:

FC300, or equivalent
Airend Discharge to
Receiver/Separator Inlet
-32 JIC
Parker-Hannifin 206, or Aeroquip

NOTES:
1. All hoses terminate at marked bulkhead fittings on drive end of machine, except oil cooler
connections, which are on the cooler side of the compressor module.
2. All hoses terminate in Type I (SAE J516 female swivel straight), 37
°
JIC flare fittings on each end.
3. Ports “B” and “C” on oil temperature bypass valve can be connected to either port on the oil cooler.
Oil cooler performance is not sensitive to flow direction.
4. 2 inch NPT to –32 JIC adapter and fitting for airend discharge pipe is customer supplied.
Compressor Discharge Piping
The connection between the compressor package and the receiver separator must be furnished by the
customer. It is recommended the customer use a flexible line with an inside diameter of the same size, or
larger than the compressor package discharge connection. All piping must be certified safe for the
pressures and temperatures involved.
