Your benefits

Protection guaranteed
These drive components – and thus the entire gearmotor – are ATEX-compliant.

Utilize limited space
Our F..EDR.. parallel-shaft helical gearmotors have a compact design and efficiently utilize available space.

Optimize power
The modular design enables a number of different combinations of EDR.. motors and parallel-shaft helical gear units.

R..EDR.. explosion-proof helical gearmotors

Protection and compact design – all in one component

Looking for a compact and safe drive solution for potentially explosive areas? The F..EDR.. parallel-shaft helical gearmotors are ATEX-compliant, ensuring you're always on the safe side.

Due to their design, the standard parallel-shaft helical gear units from the F series save installation space. Combined with the EDR.. motors, the result is a complete ATEX-compliant gearmotor in accordance with equipment group II in categories 2GD or 3GD.

Our explosion-proof F..EDR.. parallel-shaft helical gearmotors can thus be used without any difficulty for all your applications in sensitive gas zones 1 and 2, as well as dust zones 21 and 22. You won't have to compromise with these gearmotors – instead, you get continuous protection and compact drive power.

To ensure maximum power variation, 10 different motor sizes deliver a power range from 0.12 kW to 45 kW. The modular design of the F parallel-shaft helical gear unit offers you a vast spectrum of variation and customized configuration options.

This way, you'll always find the right solution for your materials handling technology and process engineering systems, particularly if you're looking for high performance within a small area.
