the arrows cast on the body. See Figure 3.
Figure. 3 - Rotation
4. Mount the compressor in a position where it is protec-
ted from dirt, debris and road spray. The mounting
location should allow for regular inspection, cleaning
and maintenance. The inlet filter should be positioned
to draw in clean, cool air, and should be mounted
away from any engine heat and exhaust. See Figure 4.
Figure 4
3.2 Drive systems
Avariety of drive options are available for the compres-
sor, including vehicle mounted, drive shaft, hydraulic
motor and flexible coupling. CAREFULLY follow all the
recommendations provided here for your application. In
ALL cases, the drive shaft MUST be capable of provi-
ding for a constant compressor speed and MUST NOT
subject the compressor to excessive start-up torques.
Driver - Vehicle mounted
1. Speed governors are required.
2. Power Take-off (PTO) MUST provide for the correct
compressor operating speed.If PTO gear box has a
“High/Low” range, ensure that the correct range is
selected.
COOLING
The compressor is cooled by two fans, drawing in cool air through
the cowls, and blowing hot air across the body.
NOTE
At least 7.85” (200 mm) must be left around the cowls to ensure
the compressor does not overheat.
Airflow
Install inlet filter away from road
spray, engine exhaust and any
hot air coming off the engine.

Figure 5
1. Square slip joints are NOT recommended.
2. Drive shaft length should be as short as possible and
the drive shaft MUST be balanced.
3. The drive shaft and compressor shaft MUST be paral-
lel within 1° and have a maximum of 10°compound
misalignment. See Table :
4. Universal joints MUST be in phase, with the drive
shaft slip joint at mid-position. Use an even number of
universal joints.
5. If the drive shaft is fitted to a PTO, a torque limiting
device MUST be fitted to prevent damage due to pos-
sible compressor failure/seizure.
3.4 Hydraulic drive
1. If the compressor is to be driven hydraulically,
MOUVEX can supply a standard Drive Kit for direct
mounting of the hydraulic motor or hydraulic pump.
MOUVEX can also supply the hydraulic motor ; See
figure 6.
Figure 6
2. Ensure the motor is installed and piped to give the
correct rotation. If required, a drain line, returning to
hydraulic reservoir tank, should also be installed.
3. If the couplings are aligned correctly, the outer plastic
sleeve should have 0.19 inch (5 mm) axial play
through 360° rotation. This can be checked by remo-
ving the inspection plate ; See figure 6.
THE DISCHARGE PIPE OF THE COMPRESSOR (THE TEM-
PERATURE CAN BE OVER 200°C) CAN NOT GO CLOSE TO
THE COUPLING SUCTION PORTS. IF NOT POSSIBLE TO AVOID
IT, INSTALL A DEFLECTOR TO PROTECT THE COUPLING
FROM SUCKING HOT AIR.
Base mounted direct drive
Flexible coupling
When base mounted and coupled to a drive (i.e.: electric
motor), use a flexible coupling.
1. Coupling angular and parallel alignment MUST be
maintained in accordance with coupling manufactu-
rer’s instructions ; See figure 7.
Figure 7- Coupling alignment
NOTICE :
USE OF EXCESSIVE FORCE WHEN FITTING THE COUPLING
FLANGE TO THE COMPRESSOR SHAFT CAN CAUSE BEA-

3.5 Piping
1. Piping MUST be at least as large as the compressor
suction and discharge connections.
ALL piping MUST be adequately supported to prevent
any piping loads from being placed on the compressor.
2. The suction side of the compressor MUST be fitted
with an adequately sized air filter, which MUST be pro-
tected from water, road spray, or other debris. This fil-
ter is available from MOUVEX. Use of wrong filter will
void warranty. The compressor is delivered with an
inlet connection kit which is installed as follows :
Composition of the kit :
Assembling procedure :
• To cut the hose to the length requested.
• To fold back the end of the wire inside.
• To screw home the humps at the 2 ends.
• Result :
• To pass a heat-shrinkable sleeve on an end and to
center it on the end of the hump. To retract gradually by
means of a heat gun. Attention not to point the gun
towards the hose not covered, risk of perforation.
To proceed in the same way at the other end.
• To check the hose is perfectly clean inside, and to remove
the protections caps on the compressor.

to tighten the clamp : aluminium flange.
Example with B200 :
• To proceed in the same way with the air filter.
• To then suspend the hose while taking care to protect
it from any friction and the potentially hot bodies such
as muffler.
3. The compressor MUST have an adequately sized
pressure relief valve installed approximately 30 inches
after the compressor discharge ; See figure 8.
Figure 8 - Typical compressor installation
4. If a backflow is possible, an adequately sized check
valve MUST also be installed in the discharge piping.
This check valve MUST NOT be mounted in a way
that broken pieces could fall into the compressor.
ENTERPRISE combination relief/check valves are
supplied with all Enterprise compressors and MUST
be used.
5. Ensure that ALL components are capable of operation
at the maximum system pressure limits and that all
vessels are adequately protected by SEPARATE relief
valves.

from sideplate. Remove circlip (5) ; See figure 17.
Figure 17
5. Tap out lip seal (4) using a drift. USE CARE not to
damage sideplate when removing seals.
6. Thoroughly clean sideplate and bearings. If either side-
plate or bearings show any damage or wear, they must
be replaced or serviced. Slight damage or scoring to
the sideplate may be carefully filed off.
5.7 Sideplate assembly
1. Before starting, place the sideplate (1) face down on
a flat, clean surface. Take care not to scratch or dama-
ge the sideplate.
2. Using a properly sized seal punch, tap in a new wiper
seal with the lip down, facing the rotor, to the full depth
of the recess ; See figure 18.
Figure 18
3. Using a circlip pliers, install the circlip (5) into the side-
plate ; See figure 19.
Figure 19
4. Lightly grease a new sideplate oil seal (6). Using a
properly sized seal punch, insert into bearing recess
with lip up, facing the bearing. Ensure the seal is flush
with the bottom of the recess ; See figure 20.

5. From the rotor side, push in the distance sleeve (3),
through both seals, until it is flush with the face of the
sideplate ; See figure 21.
6. Lightly grease a new bearing cap oil seal (8). Using a
properly sized seal punch, install the oil seal into the
bearing cap with le lip up, so that it will face the bearing ;
See figure 22.
Figure 22
7. Pack the bearing with Mobil SHC Polyrex™ 462 grease,
or equivalent, and insert into sideplate.
8. Install a new bearing cap O-ring, plus any shims, and
attach the bearing cap to the sideplate with three M10
capscrews (11). Tighten the capscrews to 26 lbs ft (35 N.m) ;
See figure 23.
Figure 23
5.8 Setting sideplate clearance
1. Prior to attaching the sideplate to the compressor
body, check the end clearance between the rotor and
sideplate using two feeler gauge strips. Ensure the
rotor is seated in the sideplate. Use a rubber mallet to
tap on free end if necessary.
2. With a feeler gauge on each side of the rotor shaft, as
shown on Figure 24, check the clearance.
Allowable Clearance :
0.004” to 0.005” (0.100 mm to 0.125 mm)
Figure 24
3. The sideplate clearance can be adjusted by changing
the thickness of the bearing cap shim used.
4. Mark each sideplate “CW” (clockwise) or “CCW”
(Counterclockwise) to identify which end of the rotor
the clearances were set to.
NOTICE :
BE SURE TO MATCH THE CORRECT SIDEPLATE WITH THE
CORRECT END OF THE ROTOR.

5. MAINTENANCE (continued)
5.9 Compressor assembly
1. Stand the compressor body, ports down, on “V” blocks
or packing as shown in Figure 25. Use care during the
assembly process to avoid any contamination. All
internal surfaces of the body, rotor, blades and side-
plates MUST be free of all debris or grease.
Figure 25
2. With the new sideplate O-ring installed, attach the
clockwise (CW) sideplate to the clockwise (CW) end
of the body. Ensure the sideplate surface is free of all
grease. Install three M10 capscrews (7), torquing to
26 lbs ft (35 N.m) and one M8 shoulder screw (9), tor-
quing to 7 lbs ft (10 N.m).
3. Slide the correct end of the rotor into the body, being
careful to keep all components clean and to avoid
damaging the plating on the rotor and body.
IMPORTANT :
Match arrows on rotor with arrows on compressor
body. If the arrows do not match rotation, the sideplate
or rotor must be changed to match ; See figure 26.
Figure 26
4. With blades and hands free from oil or grease, slide
blades into rotor slots, ensuring that the angle of the
blade tip matches the arrow cast on body bore, as
shown below.
5. Install second sideplate assembly as instructed in step 2
above. See figure 27.
Figure 27
6. Attach the fans (11) and split sleeves (4) with the M8
set screws (10) coated with Loctite®* 243. Torque the
set screws to 11 lbs ft (15 N.m). See figure 28.
Figure 28
7. Install both cowls (12 and 13) over the fans with the
M10 cowl screws (8). Torque cowl screws to 26 lbs ft
(35 N.m). See figure 29.
