Custom Compressors and Vacuum Pumps for Space Development and Flight
Scroll Technology for Life Support Systems

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

Life support systems (LSS) are a key part of space exploration, providing a safe and habitable environment for humans as we venture further into space. As the public and private sector race to address technology gaps that prevent LSS from being more reliable, efficient, compact, and lightweight, Air Squared is working in parallel to develop scroll technology that can help:

  • Liquid-Cooling Integrated in a Scroll Vacuum Pump for Urine Processing on the International Space Station
  • Staged Scroll Configurations to Support CO2 Collection and Oxygen Generator
  • Spinning Scroll Architecture for CO2 Removal
  • Oil-Free Scroll Refrigeration Design for Environmental Control

Air Squared can support next-generation life support systems with compressors and vacuum pumps that leverage over thirty years of oil-free scroll development experience and a passion for engineering that drives innovation.

Experience Matters

Air Squared has developed scroll solutions for applications in our atmosphere, the Martian atmosphere, and everything in between.

Show Mars2020

On April 20, 2021, a compact scroll compressor onboard the Perseverance rover helped NASA produce oxygen on another planet for the first time. The achievement represents the biggest milestone in Air Squared history, only made possible by an engineering team deeply rooted in innovation for over thirty years.

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.
