Rotrex air compressors are built on a fundamentally different technology: a patented planetary traction drive that sets them apart in industrial and fuel cell applications. Unlike traditional gear- or belt-driven compressors, the Rotrex system uses a toothless, friction-based drive that enables exceptional reliability, efficiency, and scalability.

Built for Demanding Environments

The compact traction drive eliminates backlash and reduces mechanical wear, making the system highly resistant to external shocks, vibrations, and air contaminants. This ensures reliable operation in industrial and automotive environments where uptime and durability are critical.

High Efficiency at Any Scale

By combining a low-speed PMSM (Permanent Magnet Synchronous Motor) with the traction drive, Rotrex compressors achieve impeller speeds up to 240,000 rpm — delivering aerodynamic efficiencies of up to 80%. This design allows for quiet, compact, and energy-efficient operation across a wide performance range.

Scalable Power, Custom Integration

Rotrex compressors are fully scalable for systems up to and beyond 200 kW. Thanks to in-house design and manufacturing, each unit can be tailored to meet specific customer needs — whether for fuel cell stacks, industrial systems, or custom OEM integration.
