Notes：

• 1HP=0.735KW

• The above specifications for piston air motors are for performance at ambient temperature of 20°C. The viscosity of the grease inside air motor housing will change if surrounding temperature decreases, the speed will also decrease.

• The performance specifications of the pneumatic motors refers to the value when the exhaust side pressure is normal atmospheric.

Features

· High Starting Torque: Excels in applications requiring high starting torque and the ability to handle sudden load increases, often performing better than electric motors of similar size under stall conditions.

· Variable Speed & Reversibility: Speed is easily controlled by adjusting the air flow (via a throttle valve), and direction is instantly reversed by switching the inlet and exhaust ports, typically using a 4/2 or 5/3 directional control valve.

· Intrinsically Safe & Explosion-Proof: As it does not generate sparks or risk of electrical overload, it is ideal for hazardous environments with flammable gases, vapors, or dust (e.g., mining, chemical plants, painting booths).

· Overload Capability & Robustness: Can be stalled indefinitely without damage from overheating (unlike electric motors). It is generally robust, durable, and resistant to harsh conditions including moisture, dust, and extreme temperatures.

· Simple & Reliable Design: Requires minimal maintenance-mainly lubrication and air filtration. It is compact and offers a high power-to-weight ratio.

Working fluid: compressed air
