Feature

• Air motor for one-way rotation only. Rated speed is 1800rpm and can be used in the same way as an electric motor.
• The dimensions of the output shaft and mounting flange are the same as those of the motor equivalent to the rated output.
• You can change the direction of rotation by rearranging the components.
• It can also be used vertically.
• Mounting methods include face, flange, and base.

Structure

• The rotor is eccentrically installed in the casing, and vanes that slide in the circumferential direction are inserted into the rotor.
• Air pressure is applied to the bottom of the vane to seal the tip of the vane and the casing.
• Compressed air entering from the air supply port pushes up the vanes and rotates the rotor.
• Air that has done its job is exhausted through the other exhaust port..

Note

• Please specify the direction of rotation. Connect the air supply to the port marked IN.
• Be sure to install an air filter and a lubricator (line oiler) in the air supply line.
• Avoid long-term operation at the rated speed or higher as it may cause trouble.
• The minimum practical rpm is 800r.pm. If using below this, select the one with a reduction gear.
• It is not possible to control the exhaust flow rate (meter-out control).
