Fuel Cell Compressors
Our Fuel Cell Compressor Range
High-Speed, Oil-Free Centrifugal Compressors for Clean Energy Applications
Neo Air Systems’ fuel cell compressors are engineered for precision, reliability, and zero oil contamination. Designed specifically for hydrogen and clean energy systems, these compact, high-speed centrifugal units deliver the controlled airflow that modern fuel cell stacks demand — without the risk of oil contamination that can permanently damage membrane electrode assemblies (MEAs).
Our compressors operate on air bearings, eliminating the need for lubrication entirely. Combined with high-speed brushless DC motors and liquid cooling, they offer exceptional power density in a compact, lightweight package — ideal for automotive, stationary power, and marine fuel cell applications where space and weight are at a premium.
From development-stage prototypes to production volumes of up to 50,000 units per year, Neo Air Systems can support your programme at every stage. Our engineering team works closely with customers to match compressor specification to stack operating conditions — flow rate, pressure ratio, inlet temperature, and control interface.
