This reversible stainless steel air motor produces a maximum output power of 0.3 kW at a controlled free speed of 450 rpm, making it an ideal pneumatic motor for applications where precise, low-speed torque is paramount. The robust stainless steel construction ensures outstanding corrosion resistance, while the ATEX certification qualifies this air motor for use in hazardous and potentially explosive atmospheres, meeting the stringent demands of petrochemical, pharmaceutical, and offshore industries. Performance specifications reinforce its suitability for heavy-duty tasks, with a minimum starting torque of 12.6 Nm and an impressive stall torque of 19.6 Nm, ensuring reliable engagement even under high-resistance load conditions. The reversible operation adds versatility to the unit, allowing directional control suited to a wide variety of drive and mixing applications. Unlike a conventional air powered die grinder focused on high-speed cutting, the MR39-450-KSL-ATEX is purpose-built for controlled torque delivery at reduced speeds, making it equally effective as a standalone pneumatic motor or integrated drive unit. Its stainless steel body resists wash-down and chemical exposure in food-grade and process environments. This Chicago Pneumatic air motor is the trusted choice for engineers specifying safe, durable pneumatic solutions in Zone 1 and Zone 2 classified hazardous locations.Product Feature: Designed with limited retention areas on the housing and double viton nose seals to prevent contamination risk Low friction and lubrication-free design of vanes for ruggedness. Sustain stall torque loading indefinitely. Short and compact planetary gear system for versatile solutions Long lasting efficiency with low air consumption design Strong starting torque for mobility during operation About MachineRefurb: MachineRefurb is an e-commerce platform specialising in replacement parts, spares and consumables for construction, agriculture and industrial machinery, serving customers across Ireland, the United Kingdom and Europe.
