Spinning scroll technology provides aerospace applications the lightest compressor and vacuum pump solution available.

Oil-Free Design

Oil-free scroll technology offers a non-lubricated alternative to traditional technology like piston, diaphragm, and vane.

Compact Footprint

Unique staged and co-rotating scroll configurations allow scroll compressors and vacuum pumps to fit in small envelopes without sacrificing performance.


When minimal power consumption is critical, leverage the inherent efficiency advantage of orbiting and spinning scroll technology.

Gases Other Than Air

With several patented semi-hermetic configurations, scroll compressors and vacuum pumps can be used for far more than moving air.

Elevated Temperatures

Using patented liquid-cooled scroll technology and stainless steel or other alloys, solutions can be designed to withstand harsh temperatures and environmental conditions.
