Oil-free turbo compressors with gas bearings

Ultra-high-speed oil-free turbocompressors with gas bearings offer solutions for applications that require the following features:

  • Compact
  • Long service life
  • low weight
  • high efficiency

Compared to standard speed compressors, our systems are up to 100 times lighter, smaller and yet highly efficient.

The turbo compressor product family covers a wide range of pressure ratios, pressure differentials, mass flows and volume flows.
The turbo compressors can be operated with a wide variety of fluids and used for different inlet conditions, e.g. positive or negative pressure. Due to the non-contact gas bearing, 100% oil- and lubricant-free compression of air, refrigerant, inert and noble gases, e.g. argon (Ar) or helium (He), is possible.

We will be happy to calculate the characteristic curves for your specific application and offer you both a standard and a customized solution.

Optimal results are achieved by combining the compressors with our range of converters.
