SECTION 4 – SYSTEM DESCRIPTION
General
The CM air compressors are semi-packaged, air cooled units designed for power take-off applications.
Each unit is designed to operate at ambient temperatures from - 10°F to 125°F (-23.3°C to 51.7°C). For the
actual delivery of each unit at its rated operating pressure, refer to the typical General Data Decal supplied
with each unit, and to the table in Section 5.
The unit includes an oil flooded, rotary, screw-type air compressor, a compressor inlet system, a capacity
control system, a compressor lubricating oil system, a compressor discharge system as well as basic
instrumentation. The compressor inlet system includes an air intake cleaner with a service indicator. The
capacity control system includes a pressure regulator linked to a compressor inlet unloader valve. The
compressor lubricating oil system includes an air-cooled type oil cooler, an oil filter, and oil control valve and
an oil separator tank and air receiver. The oil cooler is of the fin and tube-type construction that requires
forced draft cooling air. Basic instrumentation includes compressor discharge air pressure and temperature
gauges, and air cleaner restriction indicator.
The enclosure cabinet, in which most of the components are mounted, is of heavy gauge sheet steel and is
equipped with easy opening access panels for performing routine maintenance functions. Most routine
service can be performed without removing any panels.
Compression in the screw-type air compressor is created by the meshing of two sets of helical rotors (male
and female) on parallel shafts enclosed in a heavy-duty cast iron housing with air inlet and outlet ports
located at opposite ends. The male rotor has four lobes, 90 degrees apart and the female rotor has six
grooves 60 degrees apart. The grooves of the female rotor mesh with and are driven by the male rotor.
Thrust taper roller bearings at the rear of the air end prevent longitudinal movement of the rotors. As
rotation of the compressor occurs, the rotors unmesh and free air is drawn into the cavities or pockets
between the male rotor lobes and the grooves of the female rotor. The air is trapped in these pockets and
follows the direction of rotation of each rotor. As soon as the inlet port is closed, the compression cycle
begins and the trapped air is directed to the opposite or discharge side of the rotor housing. As the rotors
mesh, the normal free volume of air is decreased and the pressure increased until the closing pocket
reaches the discharge port. Cooled lubricating oil is admitted to the compressor by being injected, in
metered amounts, directly into the rotor housing so that it passes on with the air being compressed. This
removes the heat of compression to a large degree and results in a relatively low, final discharge air
temperature.
Since the CM Series compressor is of the positive displacement type, an air flow control system must be
provided to regulate the volume of air passing through the compressor to match the amount of service air
required by the customer.
Constant speed control unloads the compressor at a predetermined pressure while the driving unit continues
to operate at full speed. This is accomplished by an air operated regulator closing off the intake to the
compressor in an infinitely variable or stepless manner through the inlet unloader valve.
The discharge air pressure can be controlled between 77 and 200 psig (531 to 1379 kPa) by simple
readjustment of the speed and pressure regulator adjusting screw.

Manual - vhp300cm - 17 06/20/00
SECTION 5 - INSTALLATION
Location
After the type of drive is determined, satisfactory installation depends upon the ability of the installer. Refer
to the appropriate foundation plan for the dimensions of the compressor package and the appropriate
separator foundation plan for the dimensions of the combination primary oil separator tank-air receiver and
the secondary separator tank (hereafter called the receiver separator).
Choose a clean, relatively cool location for the compressor package, and provide ample space around the
unit for general accessibility and to ensure effective heat dissipation. Extreme care must be taken in
locating an air-cooled unit of this type so there is an unrestricted supply of air to the cooling fan, which pulls
air over the oil cooler core. The fan discharge air must flow away from the unit so that it may be readily
dissipated to atmosphere without recirculating hot air to the fan intake. Any recirculation of the cooling air
may result in an excessively high compressor operating temperature. The compressor package must be
located so the compressor discharge temperature gauge and the air cleaner service indicator will be fully
visible. Included with the compressor package is a compressor discharge pressure gauge and a discharge
temperature gauge.
For the installation of the receiver separator, choose a location that is on the same level as or lower than the
compressor package. Ample space must be provided around the receiver to ensure the proper installation
of all piping connections. In addition, the receiver separator must be located so that the separator element
may be removed for inspection and service. Refer to the appropriate separator foundation plan.
A condensate drain valve is factory supplied with the receiver separator. When installing the receiver
separator, provision should be made for easy access to this drain valve as it will be necessary to drain the
condensate daily before starting the unit.
NOTE
The condensate drain valve and line must be
located as the lowest point in the lubricating
and cooling oil system for proper condensate
removal.
The valve may also be used as a service valve for draining the lubricating and cooling oil at periodic change
intervals.
Exact level is not absolutely necessary, but it is recommended the unit be leveled with a sight glass or a
carpenter’s level set on the compressor housing. Leveling may be accomplished by shimming the unit near
the unit’s bolting holes. Be sure to use steel shims. Mounting holes are provided on the bottom of the base
and weld nuts are provided on the sides of the frame. Either may be used for mounting.
Inlet Piping
Each unit is supplied with standard air cleaners to protect the compressor from normal air-borne dust and
dirt. If necessary, the air cleaners may be removed and remotely mounted for ease in accessibility.

Manual - vhp300cm - 18 06/20/00
PIPING
General
As CM 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:
LOCATION SIZE HOSE TYPE
Compressor Module to Oil Temp
Bypass Valve Outlet (Filter) -12 JIC Parker-Hannifin 213, or Aeroquip FC350, or equivalent
Compressor Module to Hydraulic
Supply -12 JIC Parker-Hannifin 301 or equivalent

Airend Discharge to
Receiver/Separator Inlet -32 JIC Parker-Hannifin 213, or Aeroquip FC350, or equivalent
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.

Manual - vhp300cm - 19 06/20/00
Receiver separator Discharge Piping
The receiver separator discharge piping must be furnished by the customer. Refer to the appropriate
separator fitting location for a typical piping arrangement for these units. A minimum pressure valve and a
manual shut-off valve is supplied with each unit and must be piped into the customer’s system as indicated.
The minimum pressure valve is supplied to maintain approximately 77 pisg (531 kPa) in the air receiver tank
to ensure proper oil circulation and also to prevent excessive oil carryover into the customer’s air service
system. The manual shut-off valve must be installed between the minimum pressure valve and the
customer’s air service system to serve as an isolation valve.
In addition, whenever this unit is connected to a high volume customer’s service air system, a terminal
check valve must also be installed downstream of the minimum pressure valve and the isolation valve to
prevent air from the system from bleeding back into the compressor system on shutdown.
Wiring
The compressor is protected against overheating by a thermal-type discharge air temperature switch located
in the compressor discharge piping. A “normally-closed” type thermal switch, factory set at 248°F (120°C),
is supplied as standard equipment on these units. This switch is supplied for 12/24 volt DC. As an option,
this switch may be supplied for 125 volt AC. A thermal sensor switch, also set at 248°F (120°C), normally
closed, is provided as extra protection in the receiver separator. It is to be wired in series with the airend
temperature switch by the user. This switch is supplied for 12/24 volts DC, with optional AC switches
available as an option.
Driver
The installation of a CM Series Compressor with any drive such as a power take-off drive or a hydraulic
motor drive is very flexible. The proper rotation of the compressor is clockwise when viewed from the driver
end.
NOTE
Because the compressor is of the axial
screw type, the rotation cannot be changed.

This unit is normally driven be a hydraulic motor directly mounted to the SAE adapter attached to the airend.
The standard interface is for 1.75”, 13 tooth, 8-16 DP/30°splined shaft. Mounting flange is SAE “D”.
Alternatively, SAE “C” is available.
A drive shaft from the source of power take-off can alternatively be used to drive the compressor. It is
extremely important that the angularity of the drive shaft, including the universal joints, be within the limits
specified by the manufacturer. The power take-off shaft and the compressor rotor drive shaft must always
be parallel. This gives the same angle at each universal joint and prevents excessive wear. The forks of
the universal joint on the drive end must be installed parallel to the forks on the driven and universal. There
are many types of universal joints that can be used. However, a constant velocity universal joint as
previously described will reduce the possibility of torsional vibration. If a slip joint or spline is used on the
drive system, it should be placed between the two universal joints for best results.

Manual - vhp300cm - 20 06/20/00
Regulation
The standard regulation system supplied with CM Series Compressors is designed to provide capacity
control for the compressor only. Variable speed control of a driver engine is possible with additional
equipment. Consult Ingersoll-Rand Company, Specialty Products Department for technical assistance for
these applications.
The adjustment and operation of the standard regulation system is described in Section 6, Operating
Instructions.
