Oil-Free Scroll Compressors for Aerospace
Scroll Technology for On-Board Oxygen Generation Systems

Scroll compressor solutions from Air Squared are compact, efficient, and used on several commercial and military airframes - ideal for airborne oxygen generation.

On-board oxygen generation systems (OBOGS) eliminate the heavy steel bottles required by liquid oxygen systems, and in turn, significantly reduce weight, risk, and maintenance. An air compressor is a key part of the pressure swing adsorption process used to generate oxygen, providing pilots an unlimited source of oxygen-enriched breathable air.

When compared to piston compressors, oil-free scroll compressors are reliable, durable, and efficient, making them ideal for aerospace applications. Additionally, Air Squared can design around unique packaging and weight requirements, so your device can be as compact and lightweight as possible.

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.
