Ingersoll Rand 7809-B Reversible Air Power Motor is engineered to provide dependable pneumatic rotary power for industrial machinery requiring high output torque with bidirectional operation. As part of the 2200 Series, this air motor delivers 0.70 HP while operating at a free speed of 850 RPM. Equipped with a double gear reduction and a reversible configuration, the 7809-B is well suited for OEM machinery, material handling systems, automated production equipment, industrial processing applications, and other pneumatic drive systems where controlled speed and reverse rotation are required.
The 7809-B develops a 15.50 lb-ft stall torque, representing the maximum torque produced when the output shaft is prevented from rotating. Its reversible design enables both clockwise and counterclockwise operation, while the double-stage gear reduction efficiently lowers output speed and significantly increases available torque for demanding industrial applications.
