Custom Compressors and Vacuum Pumps for Space Development and Flight
Scroll Technology for In-Situ Resource Utilization

Scroll technology from Air Squared can support ISRU processes that bring us one step closer to calling space “home.”

In-Situ resource utilization (ISRU) refers to the process of using local materials on other planets (or moons, asteroids, etc.) to generate resources instead of transporting them from Earth. ISRU provides a critical pathway for humans to live and work for extended periods of time in deep space, drastically reducing payload and in turn, launch cost.

The production of O2 and H2O are generally considered the most important ISRU processes for lunar and martian exploration. On April 20, 2021, a compact scroll compressor from Air Squared on board the Perseverance rover helped NASA produce oxygen on another planet for the first time. This important milestone demonstrated the potential of ISRU and the viability of scroll technology to support it.

Looking forward, Air Squared is already developing a larger-scale scroll compressor for CO2 collection and applying over thirty years of scroll design experience to develop technology that will support future ISRU processes.

Air Squared has a long track record of developing innovative scroll solutions that reduce the size and weight in advanced exploration systems.

Spinning scroll technology provides space 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.
