»
Silencer supplied with motor.
»
Motor is reversible.
»
Maximum temperature -20°C to +60°C
(-4°F to +140°F).
»
Maximum temperature for non ATEX
applications: -20°C to +80°C (-4°F to
+176°F).
Airsupply lubrication and filtration:
Use 64 micron filtration or better. Choose a
lubricator suitable for the flow required. Prior to
initial startup, inject oil into the inlet port.
Lubricator drop rate 4-5 drop / minute
continuous operations
Lubricator drop rate 9-12 drop / minute
intermittent operation.
Maximum speed 4000 rpm
Life time depends highly on operational speed
and air pressure.

TORQUE - PRESSURE
W hen designing for applications where the
minimum start torque requirement is equal to
the running torque (as for example on hoists),
the motor should be operated in the area below
the min starting torque. This will ensure that the
motor will always have adequate starting torque

AIRLINE FILTRATION AND LUBRICATION
Use 64 micron filtration or better. Choose a lubricator
suitable for the flow required. Prior to initial start-up,
inject oil into the inlet port.
Lubricator drop rate 4-5 drops/minute continuous operation.
Lubricator drop rate 9-12 drops/minute intermittent operation.
Max. Overhung Force on motor shaft 170 N (40 lbf.).
Axial loads should be kept to a minimum.
Attitude: The motor can be operated in all positions.
Maximum temperature -20°C to +80°C (-4°F to +176°F).
Muffler supplied with motor.
Motor is reversible.
A pressure regulator should be used to control the
air pressure to the motor, to limit the maximum
output torque applied to the driven assembly.
