Custom Scroll Design

Contact Air Squared to learn how custom scroll design can support fuel cell applications with the most advanced compressor and vacuum pump solution available.

Advanced Custom Design Capability for Fuel Cell Applications

For over twenty-five years, Air Squared has continuously challenged the limits of possibility with scroll technology. With an ever-expanding range of custom design capability, put our long history of innovation to work in your next fuel cell application.

Oil-Free Scroll Design

Orbiting scroll technology offers a quiet oil-free alternative to traditional technology like piston, diaphragm, and vain.


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.

Compact Footprint

Unique staged configurations allow scroll compressors and vacuum pumps to fit in small space envelope without sacrificing performance.

Elevated Temperatures

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


With patented liquid-cooled scroll technology, scroll compressors can now be designed for pressure ratios that were previously unattainable.
