air motors/gearmotors known industry wide for their rugged construction and reliability, gast air motors and air powered gearmotors are available in lubricated or oilless models. lubricated air motors come in seven basic models up to 9.5 hp (7,1 kw); motor speeds are variable from 300 to 10,000 rpm. oilless versions, which require absolutely no lubrication, come in three basic models r anging from .18 to .82 hp (0,13 to 0,61 kw) and with motor speeds up to 4,000 rpm. choose from hub, foot, face, nema c-flange, or metric d series interface mountings and clockwise, counter-clockwise, or reversible rotations; four and eight vane models are also available. air powered gearmotors are available in right-angle and in-line models offering a maximum torque range of 73 to 5,200 lb. in. (8 to 587 nm) and gear ratios from 10:1 to 60:1 single reduction gear reducers. a full line of recom- mended accessories is also available. compressed air into an air motor forces the sliding vanes out of the eccentric-mounted rotor. an extended shaft on the rotor spins to perform the work. performance b up to 9.5 hp (7,1 kw) b variable speeds to 10,000 rpm b gearmotor maximum torque to 5200 lb. in.
