»To check that the air motor is designed for use
in hazardous applications read the air motor
label:
»Hazardous zone
»Hazardous category
»Equipment group
»Temperature class
»Maximum surface temperatures
»Check the air motor before installation and
operation to see if it’s not damaged.
»Any products that are driven by the air motor
must meet appropriate ATEX approval as well
to be used in a hazardous area.
»The air motor should be connected to the
earth with a maximum earth resistance of
1Mohm. The motor can be earthed by con-
necting the motor to a base plate/gearbox
etc.
»The ambient temperature range of the motor
(-20°C to +60°C) should be observed at all
times.
»When mounting the engine on a construction
or when something is mounted on the shaft of
the air motor. Make sure that the alignment is
straight to prevent too much force on the shaft.
»An air filter should be placed in the airline
with at least 64 micron near the air motor.
»Clean surface of air motor unit thoroughly of
all dustproofing products, contaminants and
other impurities. Do this outside the hazardous
area or clean only with a damp cloth.
»A lubricator must be placed inside the main
airline near the motor. The lubricator unit
should have a bowl with enough oil for
operation and should allow the user to control
the amount of oil drop per minute going to
the motor.
»Check airline oil every time before starting.
Air motor should be supplied with oil of a
viscosity of 32. This type of oil is flammable at
a temperature of 218°C.
»Air supply to the motor should always be
taken from non-hazardous area.
»In case the motor is exposed to high vibrati-
ons during operation and when not in ope-
ration, please contact the manufacturer. High
vibrations might lead to increased inspection
interval of the bearings.
»It’s important that no dust or debris can accu-
mulate at the output shaft. This may damage
the shaft seal. If the motor is built in a closed
system or construction so that no dust or
debris can get in contact with the output shaft
the air motor can be used in any orientation.
If the motor is used is such way that the output
shaft is in contact with explosive environment
the mounting position is limited from horizon-
tal to vertical downwards. It is not allowed for
the shaft to point in any angle upwards.

Use a puller to remove pulleys, pinions and couplings. Check if the tension on the belt
pulley matches the specifications of the manufacture. Do not exceed the maximum
radial and axial forces on the shaft. If the motor shaft is connected to the part to be
driven without a coupling, check that the radial offset and axial force effect will not
cause problems.
Use only belts with <100 electrical leakage resistance to prevent static electrical
problems.
Mounting to construction
»Mount the unit to the construction. Care should be taken, when fitting drive components to the
shaft, that excessive force is not used. This will upset the shaft alignments which has been kept to a
minimum in order to give high motor performance.
»Use the proper sized fasteners.

oil of a viscosity of 32. This type of oil is
flammable at a temperature of 218°C.
»Air quality should meet ISO 8573-1:2010
class 4 for solid particles and ISO 8473-
1:2010 class 3 for water.
»For the most efficient power and control of
speed, all valves and the airlines should be
the same size as the air connections of the
motor. If the valves, airlines and other con-
nections have a longer distance than 2m (6
feet) of the motor we advise one size bigger.
»Before final connection to the motor, clean the
compressed air connection with low pressure
air to remove any dirt inside the line before
connecting to the ports of the air motor.
»A silencer is supplied with the motor. When
installed ensure that condensation cannot run
back into the motor port. Mount the air motor
with silencer pointed down or make extra
piping on the silencer.

Performance regulation
2. Air flow regulation
Air flow regulation is the best way to reduce
the output speed without the loss of torque.
The air flow can be regulated with a throttling
device. By throttling, the starting torque remains
essentially the same but the torque curve is
steeper. This means that under the same load
fluctuation, the speed fluctuation is smaller in
comparison with the pressure regulation. There
is a distinction made between the following
installation positions:
Exhaust air throttling
The exhaust air throttling is the less optimal
way of throttling relating to the durability
and the air consumption. The advantage of
this method is that the rotational speed can
be regulated constantly in the lower rotation
range. In the border area of the rotation range,
a combination of supply- and exhaust air
throttling should be used. The exhaust throttling
should be used for controlling low speed of
rotation.
Supply air throttling
The supply air throttling generates better
results in relation to the durability, the running
smoothness and the air consumption.
With the regulation of the inlet pressure and the flow rate, the performance can be adapted to the
individual application. This is done by pressure or air flow regulation or a combination of both.
The compressibility of the air generates a dampening effect in all ranges. This allows that the motor
also can be started, while it is loaded. With a load reduction, the motor reacts immediately with an
increase in speed.

1. Pressure regulation
With pressure regulation the output power
can be adjusted. When the supply pressure is
decreased, the torque and power is reduced
proportionally and the torque curve becomes
flatter. The forces inside the motor are also
reduced, which increases its durability.

Rebuild instructions
Vane motor maintenance instructions
These motors are made to precise tolerances and itisvital for
efficientoperation to achive minimum clearances throughout.
Every clearance represents an airleakage path from inlet to
exhaust, which will detract from the starting and running
characteristics.
The spacing of the rotor is of prime importance intwo ways:
1- rotor toend covers (sideclearance) (Cs)
nominally 0.050 mm (0.002")
2- rotor tobody casing (topclearance) (Ct)
nominally 0.050 mm (0.002")
To achieve the side clearance each repair kit has a series of
plastic shims, colour coded todifferent thicknesses.
Purple = 0.025 mm (0.001")
Blue = 0.050mm (0.002")
Green = 0.076 mm (0.003")
Orange orBrown = 0.102 mm (0.004")
This range of vane motors has three styles of rotor locations.
