INSTALLATION AND OPERATING MANUAL
This manual covers all models of the VCX rotary claw vacuum pump. The model number is printed on the
nameplate with the unit’s serial number.
Please identify the model number and serial number when ordering parts.
1.0 INSTALLATION
1.1 General description
VCX pumps are dry, contactless machines enclosed in a fan-cooled, ventilated acoustic sound shield.
The modular construction consists of two compartments separated by labyrinth seals: a pumping
chamber and a gear chamber. In the pump chamber, two rotary claws rotate in opposite directions. The
gear chamber contains gears for synchronization of the claw rotation. An anti-suck back valve can be
installed in the inlet flange to prevent air from flowing back into the vacuum chamber after the pump is
shut down. The pump is directly driven by a flanged motor via a coupling.
1.2 Unpacking
Inspect the box and pump carefully for any signs of damage incurred in transit. Since all pumps are
ordinarily shipped F. O. B. from Airtech’s factory, such damage is the responsibility of the carrier and
should be reported to them.
The vacuum pump is bolted to the skid with studs that are connected through the rubber feet of the pump.
Remove the nuts from the underside of the crate and remove the unit from the skid. Unscrew the studs
from the rubber feet.
The inlet and exhaust of the vacuum pump are covered with plastic caps to prevent dirt and other foreign
substances from entering the unit. Leave these caps in place until you are ready to pipe the unit to your
equipment.
1.3 Location
Install the compressor in a horizontal position on a level surface in a well-ventilated area. Leave 8”-10” of
access around the pump to allow proper cooling. Allow access to the oil sight glass in order to inspect the
oil level regularly, and the oil fill and oil drain port for easy service.

1.4 Power Requirements
A schematic diagram for the electrical motor terminal connections is located in the junction box of the
motor or on the motor nameplate. Typical wirings for Three Phase Motors are as below:
The motor must be connected in accordance with electrical codes through a fused switch in order to
protect the motor against electrical or mechanical overload conditions. The overload of the motor starter
must be set at a level equal to the full load motor current listed on the motor nameplate.
If the pump is supplied with a motor starter, it should be preset at the according to customer
specifications. Please check that these settings are in line with the voltage at your location. If the voltage
is different, please contact Airtech for motor and starter information.
Correct direction of rotation is marked by an arrow on the motor fan housing and is counterclockwise
when looking at the motor from the motor's fan side.
After electrical connections have been made, the rotation of the motor should be checked. If it is
backwards, reverse any two of the three leads at the power connection.
Warning: Motors should only be installed by a qualified electrician, who has experience in wiring
three-phase motors. Improper electrical installation can cause injury or death.
Caution: VCX pumps must not be allowed to run backwards. The splash lubrication system is not
designed for backward operation and this may result in premature failure of the rotary claw
machine.
230V
460V

1.5 Vacuum Connections
Use a pipe size that is at least the size of the pump outlet connection. Smaller pipe lines result in reduced
pump capacity.
Pumps operating in parallel on a common main line should have a manual or automatic shut-off valve or
positive action check valve installed in the suction line adjacent to the pump suction flange. The built-in
anti-suck back valve should not be used as a shut-off valve for the vacuum system. Remove the plastic
protective cap from the inlet port prior to connection of pump to the system. Should process gas contain
dust or other foreign particles, a suitable in line (inlet) filter should be connected to the inlet port. Contact
Airtech for recommendations.
The following thread sizes are standard on the pumps (NPT thread is available upon request)

1.6 Oil Filling on Gear Box
After level installation and correct rotation has been established, fill the pump with the recommended
gear oil through the oil fill port if it is not shipped without oil. Oil level should be at the 3/4 position on the
oil sight glass, as shown:
We recommend using Airtech Part Number ATO-3000-01, which is supplied by Airtech.
The following table gives the approximate quantities of oil required for each model.
Pump Model Capacity (liter)
VCX 60 0.60
VCX 155 / VCX205 0.5
VCX 100 / VCX100B / VCX 150 / VCX150B 0.75
VCX 250 / VCX250B / VCX 300 / VCX300B 1.10
VCX 255 / VCX 305 0.90
VCX 400/ VCX 505 1.10
VCX 515 1.80
Do not add fill oil with pump running! Do not overfill.
Caution: Running the compressor before adding oil to the gearbox could result in severe damage
to the unit. Use of oil that does not meet the recommended specification could result in damage to
the unit and void the warranty.
1.7 Lubrication of the bearings (VCX 400/505 ONLY)
The bearings on the drive side of the pump must be lubricated by gear oil using a splash lubrication
principle. The bearings on the non-drive side need to be greased every 5,000 operating hours (see
Section 4.3 for the maintenance schedule). Airtech supplies grease specifically for this purpose: Airtech
Part Number ATG 5400.
2.0 SAFETY
Please read the following safety notices carefully before operating the pump.
2.1 General Notices
- Please read the entirety of this installation and operating manual before operating the vacuum pump.
- Airtech shall assume no liability for any accident or failure associated with a failure to comply with
instructions in this manual.
- Only a qualified technician should operate the pump
- If the pump is not operating correctly, it must be stopped immediately.

2.2 Warning labels and their explanations
Please check and make sure that the following warning labels are clearly visible on your VCX unit:
2.2.1 Read and Understand the manual:
Read and understand this manual before using this machine
2.2.2 Burn Hazard:
Hot surface. Do not touch.
2.2.3 Loud noise Hazard
Ear protection must be worn.
2.2.4 Hazardous Voltage:
Disconnect power before opening. Contact causes severe electrical shock
2.3 Location of the labels
The warning labels shown above should be affixed on the top of the pump’s sound shield, except the
“Hazardous Voltage”label, which should appear on the cover of motor’s terminal box.
3.0 OPERATION
3.1 Start-up
Check rotation of the motor as described in Section 1.4 (Power Requirements). Fill the pump with oil as
described in Section 1.5 (Oil Filling).
Start the pump with the inlet closed. Run the pump for a few minutes and then shut down. Check the
oil level again and make sure the oil level is over 3/4 position of oil sight glass as shown on the label.
Add oil though oil fill port if necessary. Pump oil should only be added when the pump is off.

3.2 Stopping the pump
To stop the pump, turn off the power. A built in anti-suck back valve installed in inlet flange will prevent air
from back flowing into the vacuum chamber after the pump is shutdown.
Caution: Do not use the anti-suck back valve as a check valve. Consult Airtech for
recommendations regarding check valves and other accessories.
Caution: The maximum number of motor starts per hour should not exceed 10 per hour.
Excessive starting of the motor can cause overheating and premature failure of the motor. A
minimum run timer should be used with a control panel to regulate starting and stopping of the
pump.
Caution: In applications, where the quantity of water vapor is moderate, it is recommended to run
the pump for 10 minutes at least with outside air prior to shut down to prevent the vapor from
condensing in the pump.
3.3 Operating Conditions
All VCX units are designed to run at the vacuum levels for continuous operation as stated in Section 6.0
(Technical Data). Operating above the maximum vacuum level may cause severe damage to the
machine. The vacuum regulator installed in inlet flange is set to the maximum allowable vacuum level at
the factory, and a desired vacuum level below the maximum level can be achieved by rotating the
adjustment knob.
Standard VCX units are for use of dry air only, and should not be used for hazardous areas. Handling of
humid air or gases containing aggressive chemicals is possible only with specially configures units.
Consult Airtech for assistance.
Excessive back pressure on the unit may result in excessive current draw. Do not operate the vacuum
pump over 2 psi back pressure.
For operating personnel working near the pump, ear protection is recommended. If noise below the
typical dBA is required, an external sound enclosure can be added to the system, provided adequate
ventilation is provided. Please consult Airtech for recommendations.
The ambient and suction air temperature must be between 41° F (5° C) and 104° F (40° C).
Caution: Failure to ensure proper operating conditions may lead to severe injury to persons and
damage to the pump.

4.0 MAINTENANCE
VCX-Series vacuum pumps require very little maintenance. To ensure optimum performance, the
following maintenance steps should be followed:
4.1 Gear Box Lube Oil
4.1.1 Gear Oil Level
Check the oil level on monthly basis. Under normal circumstances it should not be necessary to add oil
between oil changes. A significant drop in oil level could indicate an oil leak. If the pump is leaking oil,
please check the o-rings, drain plug or oil sight glass.
Check the oil level only when the pump is shut off. Replenish oil if it drops below bottom position of the oil
sight glass.
Caution: Do not add oil while the pump is running. Hot oil can escape from the oil fill port.
4.1.2 Gear Oil Type and Quantity
Oil level should be at the 3/4 position on the oil sight glass. We recommend using Airtech Part Number
ATO-3000-01, which is supplied by Airtech. The following table gives the approximate quantities of oil
required for each model.
Pump Model Capacity (liter)
VCX 60 0.60
VCX 155 / VCX205 0.5
VCX 100 / VCX100B / VCX 150 / VCX150B 0.75
VCX 250 / VCX250B / VCX 300 / VCX300B 1.10
VCX 255 / VCX 305 0.90
VCX 400/ VCX 505 1.10
VCX 515 1.80
Do not add fill oil with pump running! Do not overfill.
4.1.3 Gear Oil Change
Under normal ambient conditions with proper gear oil, oil needs to be changed every 5,000 operating
hours. We recommend performing the first oil change after 500 - 1,000 operating hours.
Caution: If different brand of oil is being filled, the old oil must be drained completely from the
gear box.
4.1.4 Grease Supply on the bearings (Applies only to VCX 400/500)
Apply fresh grease (Airtech Part Number ATG 5400) to the bearings every 5000 operating hours, but
check the condition of grease more frequently if the pump is operating in an environment with an ambient
temperature over 68° F (20° C) and add grease when necessary. Do not over-grease. About 30 grams of
grease should be applied to each bearing. The grease can be applied with a grease gun by opening the
front cover.
Caution: The interval of lubrication stated above is based on ambient temperature of 68° F (20°C).
At 104° F (40°C) ambient temperature, the interval may be reduced to 2,500 operating hours.

4.2 Inline (Inlet) Filter
Check inline (inlet) filter on a weekly basis. The filter cartridge should be cleaned or replaced if it is dirty.
Consult Airtech for replacement elements.
Caution: Depending on the mounting position of the filter, be careful not to allow accumulated
foreign material to fall in the pump suction inlet when removing the filter cartridge. Horizontal
filter installation is recommended to prevent this.
4.3 Maintenance Chart

5.0 Troubleshooting
Problem
Probable Cause
Remedy
Motor Starter Trips
Incorrect voltage (lower than
required).
Check voltage at the motor and
correct any sources of voltage drop
in the system. Check wiring to
ensure it is properly sized according
to National Electrical Code
requirements.
Incorrect wiring of the motor.
Ensure the motor is wired according
to the instructions contained in the
motor junction box. Correct
placement of the bridges is
necessary to configure your motor
for the proper voltage.
Motor starter is not set correctly or
is too small for the application.
Check to ensure the motor starter is
set for the full load amps at the
operating voltage as indicated on
the
motor nameplate. Be sure to
multiply the full load amperage by
any service factor that appears on
the motor. If the current required is
outside the range of adjustability of
the starter, replace the starter with a
properly sized starter.
Motor starter trips too fast.
A motor starter with a high current
trip delay should be used to avoid
nuisance trips on startup.
Insufficient Capacity
Blocked inlet mesh
Check and clean mesh as
necessary. Replace damaged
mesh.
Do not run the machine without the
inlet mesh in place, as even small
solids entering the pumping
chamber
can cause the unit to fail.
Leaks in the vacuum piping
Check process piping for leaks. To
confirm the leaks are in the piping,
run the pump isolated from the
piping and confirm pump reaches
ultimate vacuum per the data
sheets. If the pump does meet the
ultimate vacuum, then there is a
problem in the piping that must be
corrected. A rate of rise test can be
run to determine the leakage rate.
Leaks can be found by a soapy
water or smoke test..

Problem
Probable Cause
Remedy
Insufficient Capacity (cont’d)
Improperly operating relief valve
Check the adjustment of the relief
valve. Under normal conditions, the
VCX should not have air flowing into
the relief valve if operating in the
standard range of pressures. If air is
detected entering the relief valve
(place a cardboard scrap near the
suction of the relief valve and see if
vacuum is detected –if the scrap is
held to the relief valve by the
vacuum, then the relief valve is
active). If the relief valve is active,
adjust it so that no flow is detected
at
the operating pressure, which must
be in the range of operation shown
on the data sheet.
Insufficient Vacuum
Blocked inlet mesh
(See blocked inlet mesh above)
Improperly operating relief valve
See Improperly operating relief
valve, above.
Bad gauge
Replace the gauge with a good
quality vacuum or pressure gauge.
Leaks in the system piping.
See Leaks in the vacuum piping for
VCX operation or leaks in the air
piping for PCX operation above.
Improperly sized piping.
Check the pressure at the pump
and
at the process with the same gauge.
If the pressure drop exceeds the
design value (rule of thumb is 10
percent of the operating pressure,
maximum) then the piping is too
small. Change the piping between
the pump and the process to a
larger
size.
Pump does not achieve ultimate
vacuum
Leak on the suction side
Check the piping for leaks as noted
above.
Relief valve set incorrectly.
Reset the relief valve as necessary.
Bad gauge
Replace the gauge with a better
quality vacuum gauge.

Problem
Probable Cause
Remedy
Operating Temperature too High
Ambient temperature too high
Provide adequate ventilation for
the installation area so that the
ambient temperature never is
above 104° F.
Dirty or Blocked Mesh
(See blocked inlet mesh above)
Pump runs over set pressure.
Vacuum regulator set over the
set point or is out of order.
Set the point again or replace it
with new one.
Pump making excessive noise
Contamination of the claws
Clean the pumping chamber
and rotary claws.
Coupling insert is worn.
Replace coupling insert in
motor/pump coupling.
Pump will not operate (seized
up).
Rotary Claws, Bearings or
Gears stuck
