Notes

Refers to basic part number only. When ordering, the number of air inlets and type of connection must be specified.
10.00 degrees for elements with one air inlet. 5.00 degrees for elements with two or four air inlets.

1 Dynamic torque shown, static torque approximately 25% greater. Torque in each application is dependent upon air pressure and speed.
2 Maximum rpm is dependent upon operating conditions and varies for each application. Consult factory for applications exceeding these speeds.
3 Drum contact with worn shoes.
