Oil-Free Scroll Compressors for Aerospace
Scroll Technology for Waveguide Pressurization Systems

Oil-free scroll technology from Air Squared is being adopted on military airframes for waveguide pressurization systems, providing efficient and reliable performance in a compact and lightweight design.

Waveguide pressurization systems require clean, dry, and deionized air to the waveguide chamber to reduce corrosion of the dielectric coating and reduce internal electrical arcing. An air compressor is the heart of the system and provides the necessary pressure differential to move ambient air through the desiccant dehydrator.

Oil-free scroll technology delivers clean and dry air while offering longer life and less maintenance than alternative compressor technologies. The positive displacement nature of a scroll design also allows for effective compression even at high altitudes.

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.
