The PR02-88 is optionally equipped with an air connection. At the rear of the motor, above the electrical
connectors, there is a pneumatic push-in fitting (external hexagon M5) for a Ø 4 mm hose. Inside the motor,
a Ø 4 mm air hose is laid along the rotating shaft. This enables the user to implement pneumatic applications
with an operating pressure of max. 6 bar.
Depending on the ordering situation (pneumatic connection or "pusher" application), 1 or 2 plug-in
connections can be pre-assembled. The user also has the option of mounting a pneumatic push-in fitting at
the front of the shaft. A G1/4 (10 mm deep) and a M5 (4 mm deep) are available to the user in axial direction.
The through bore-hole in the rotating shaft is Ø 4 mm.
In the case of vacuum application, it is recommended to use a unit with sufficient power, as experience has
shown that all air coupling points generate small losses.
