Product Description HXHM16 Piston air motor Powered by compressed air,piston air motor converts the pressure energy into rotary mechanical energy. Compared to blade air motor,it has lager size and weight,lower speed and more complex structure as per power unit,but has higher starting torque,well performance in low speed and longer life span. Features: Flameproof by design.Inherently spark resistant. Positive starting torque Variable speed control Superior reliability in harsh environments Precision spotting control at low speed Standard design temperature range is 0°C through 60°C CE certification
