    The Chicago Pneumatic M3901-70-SQ delivers reliable, consistent rotational power for demanding industrial applications where precision and durability are non-negotiable. Engineered as a robust non-reversible vane air motor, this 390 W pneumatic motor provides smooth, controlled output that keeps production lines moving efficiently without the complications of electrical power sources. Designed for straightforward integration into automated or semi-automated machinery, the M3901-70-SQ operates at 70 RPM with a stall torque of 220 Nm and a minimum starting torque of 200 Nm, ensuring dependable startup performance even under load. The 12.7 mm output spindle size makes it compatible with a broad range of drive configurations, while the compact 2.6 kg frame allows installation in space-constrained environments without compromising structural integrity. As a quality air motor from Chicago Pneumatic, it benefits from the brand's decades of engineering expertise in pneumatic motor technology, translating to extended service life and reduced maintenance intervals. The non-reversible vane design suits applications requiring unidirectional torque delivery, offering consistent mechanical output that variable-speed electrical alternatives struggle to match at this torque range. This air powered solution is ideally suited for conveyor drive systems, industrial mixing equipment, packaging machinery, and any process application requiring steady low-speed torque from a compact pneumatic drive unit. Professionals specifying air tools for heavy-duty automated systems will find the M3901-70-SQ a dependable, performance-driven choice.Product Feature: 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.
