The COSMOS Air Compressor produces continuous, high quality oil-free, pre-dried air.

The COSMOS Air Compressor is the ideal solution for providing compressed air to a Zero Air and Nitrogen Generator, and for powering pneumatic valves or other applications in the lab.

The COSMOS Air Compressor can be stack to any stack COSMOS H2, Zero Air and Nitrogen generators, typically as the base unit – to give you a complete self-contained GC gas solution, even where no house supply is available.

Thanks to a unique compressor mounting system, the COSMOS Air Compressor also benefits from low noise and vibration making it relatively quiet in operation within a typical laboratory.
