ATEX motor

Certified by TÜV Süd with ATEX certificate II 2 G Ex h IIC T5 Gb X, II 2 D Ex h IIIC T100°C Db X, our ATEX motors are applicable in all explosive areas of ATEX zone 1. The purely mechanical construction avoids the development of heat or sparks during operation, which could inflame flammable substances such as alcohol, solvents or dusty or dust-producing substances. Furthermore, the motor does not need an additional electricity supply.

The motors are operable in anti-clockwise and clockwise rotation and are resilient to standstill. Of course, they are oil- and silicone-free as standard. As they are IP67 waterproof, they can also be applied in humid or dusty applications.

Extremely efficient and high-performance, our radial piston motors provide high torques while consuming only a minimum of compressed air, making it the pioneering drive technology for the future. Our motors save energy and costs of up to 90% compared to other drives such as the vane motor.
