Rotrex Fuel Cell Compressor
The Rotrex Fuel Cell compressor (”EK10AA”) is a combination of a low speed PMSM motor, coupled directly together with the patented Rotrex traction drive spinning a high efficient centrifugal compressor. The result is a class leading compressor, designed specifically for fuel cell applications, with an unsurpassed combination of efficiency, robustness/durability and high operational speed.
- Low NVH due to smooth running surfaces in the traction drive
- Robust and durable design – based on proven technology
- Clean Oil-free, linear and non-pulsing air supply
- Automotive design – high resistance to shock/impacts
- High speed shaft supported by rollers – no bearings
- Ultra-compact and flexible integration
- Class-leading efficiency

(**) With current impeller design. Dedicated impeller design is possible to match customer requirements.
Dedicated impeller geometries for maximization of aerodynamic efficiency. Compressor maps are created on our own in-house SAE flow rigs.
The EK10AA is designed for a system life of 20.000 Hours, with preventive maintenance each 5.000 Hours*.
Maintenance procedures should be able to be performed quick and safely, ensuring lowest possible downtime of the Fuel Cell. Therefore, through almost a decade of experience with the Fuel Cell industry, we have incorporated into the design, the most simple maintenance procedure to date.
The EK10AA is currently offered as B-Sample prototypes made on customer request, intended for testing/evaluation and smaller series production. Rotrex strive to offer highest level of flexibility, hence the EK10AA can be tailored to specific application requirements. Please contact us for more information.

Why Rotrex and Fuel Cells?
Rotrex has existed for more than 20 years and develops, produces and markets centrifugal superchargers for a wide range of industries based on patented traction technology for OEM, OES, and aftermarket companies worldwide.
The EK10AA is a completely new product to our product portfolio and our acknowledgement to take part of the all important, green energy transition. The air compressor for Fuel Cells is a key component; hence our aim is to assist towards a quick and safe shift from fossil fuels to zero-emission propulsion, ensuring a healthy environment for our future generations.
For the past decade, fuel cell applications has been part of our business, with references to the majority of global Fuel Cell companies.
Although the product is completely new, it is based on our patented traction drive, which has evolved and improved over more than twenty years. With the help from InnoBooster (Article, in Danish) and customer’s projects, the EK10AA is now a reality which we are very proud of!
