Tiny New Scroll Compressor Designed for Artillery Piece Delivers Big Blast of Air for Tight-Fitting Applications in Medical Equipment, Fuel Cells and Gas Boosters
Compressor provides 12 CFM @ 130 psig from package measuring just 9" x 9.4" x 12.3"
December 2002 - Air Squared's tiny P18H36 high-pressure scroll air compressor lives up to its design roots in an artillery piece by delivering a big shot of air - 12 CFM at 130 psig - from a compact package. Originally created to clean a laser window for the Army's Crusader mobile howitzer, the new oil-free unit offers designers a clean, quiet and reliable source of compressed air for medical equipment, fuel cells and natural gas boosters.
"The Defense Department approached us for a design because our technology is inherently vibration-free and completely oil-free," said Air Squared President Robert Shaffer. "This eliminated need for isolation mounts and oil removal, further reducing space requirements."
The P18H36 scroll compressor uses a pancake-type, brushless DC motor which is only 144 mm long, resulting in an overall size for the unit of just 9" x 9.4" x 12.3".
A unique liquid cooling technique used by Air Squared eliminates the need for an aftercooler - which saved space on the cannon - and allows a temperature rise of just 125°F.
The ins and outs of scroll technology
With only one moving part, scroll compressors are exceptionally reliable and durable, usually lasting the lifetime of the equipment into which they are integrated. The core of the revolutionary pump consists of two identical meshed scrolls (involute spirals), each attached on its "out" side to a flat base. One scroll is fixed, the other connected to an electrically driven eccentric. Indexed 180 degrees to each other so their spirals mesh, the scrolls fit together to form two halves of a chamber.
The indexing motion creates crescent-shaped pockets between the involutes of the meshed scrolls and the base plates. Air entering the pump gets trapped in these pockets. As the moving scroll orbits the fixed one, the pockets follow the spiral inward, getting progressively smaller and compressing the air. Finally the air is exhausted through an outlet at the center of the scrolls. Air Squared's website at www.airsquared.com has a moving graphic that clearly demonstrates scroll motion.
