    Delivering reliable, explosion-safe rotary power in the most demanding industrial environments, the Chicago Pneumatic M25-21500-KSL-ATEX reversible air motor is engineered for facilities where standard pneumatic equipment simply cannot be used. ATEX-certified for hazardous atmospheres, this compact pneumatic motor brings peace of mind to oil and gas, chemical processing, and other explosive-risk settings without compromising on performance. At the heart of this unit is a maximum free speed of 21,500 rpm and a peak output power of 0.3 kW, making it an ideal drive solution for precision rotary applications. Air consumption at load sits at a highly efficient 5.3 l/s, ensuring that compressed air resources are used intelligently across extended production runs. The reversible operation adds operational versatility, allowing engineers to adapt drive direction to suit specific tooling or process requirements on the fly. Built to Chicago Pneumatic's exacting standards, the M25-21500-KSL-ATEX shares the dependable engineering DNA found across the brand's trusted range of pneumatic motors and air tools. Its compact form factor makes integration into custom equipment, automated machinery, and bespoke rigs straightforward, while the KSL configuration ensures consistent torque delivery throughout the speed range. This air motor is the go-to choice for maintenance engineers, OEM equipment builders, and plant operators who need certified, high-speed rotary power embedded into hazardous-area machinery or specialist pneumatic drive assemblies. Product Features: 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.
