VAIREX Corporation - Fuel Cell Air Management Systems

VAIREX Corporation supplies fuel cell air management systems to stationary and mobile fuel cell system integrators worldwide. The integrated air systems include compressors, brushless DC motors, speed controls, manifolds, filters and other subsystem components as required.

The company's market leadership is based on internal R&D complimented by numerous DOE and industry supported development projects starting in 1995. The resulting technology and the products deriving from it form the basis for a range of high efficiency air management systems. We work with the fuel cell system integrator to optimize overall system performance.

VAIREX has developed a range of high performance, low cost air management systems to meet the needs of the emerging fuel cell industry and other related energy applications. These air systems are based on proprietary compressor technology. The range of capabilities includes the following product families:

REGENERATIVE AIR BLOWERS

Regenerative air blowers cover the range of pressure up to ratios of 1.3, with mass flow up to 16g/sec. This family of compact, motor driven air blowers is applicable to a wide range of stationary and mobile low pressure PEM and SOFC systems in the range of 1kW to 5 kW.

RESTRAINED VANE COMPRESSORS

Restrained vane compressors are designed for fuel cell systems operating at pressure ratios of 1.1 to 2.5 (2,500mbar) and requiring mass flows of up to 75g/sec. They provide high efficiency at low cost. The design is scalable over a wide range of mass flow requirements. The vane air systems are particularly suitable for PEM FC systems operating at medium pressures, such as stationary power systems, APUs and traction systems, operating in the range of 2kW to 75kW, or above.

For pressure ratios above 2.5, proprietary dry piston compressor configurations are available on inquiry to the factory.
