Known industry-wide for their rugged construction and reliability, the Gast Group’s range of compact, lightweight air motors are now available with II 2 GDc T4 +1ºC < Ta < +40ºC ATEX approval, which means they will work in ambient temperatures up to 40ºC. The motors are also classed as intrinsically-safe in hazardous environments, which reduces the possibility of explosion from the ignition of flammable gases.

The air motors can be used in a variety of industrial and manufacturing sectors such as food and beverage; medical, healthcare and laboratory; and environmental, with typical applications including mixing equipment; pump and conveyor drives; food and pharmaceutical packaging; and hoists and winches.

Gast’s non-lubricated air motors are available in four basic models from 0.13 to 1.86 kW (0.18 to 2.5 HP), with motor speeds up to 4,000 RPM. Oil-lubricated versions are available in seven basic models from 0.33 to 7.1 kW (0.45 to 9.5 HP) with motor speeds variable from 300 to 10,000 RPM. A range of recommended accessories is also available and bespoke versions can be manufactured to special order for OEM quantities.

Air motors can be mounted in almost any position and users can choose from hub, foot, face, NEMA C-Flange or Metric D Series interface mountings, and clockwise, counterclockwise or reversible rotations. Four vane models are available as standard, with eight vane models available for smoother running and better control for short-run applications including winches, hoists and hose reels.
