10+ years ago hospitals, laboratories and other fabricators with critical air uses purchased oilless piston compressors. Piston compressors were loud, created vibration and didn’t last long, even with proper maintenance. Once these oilless scroll compressor were introduced, they became a natural replacement for loud piston compressors.
Advantages with Oilless Scroll Compressors
The biggest advantage using a oilless scroll compressors over a piston compressor would be the duty cycle and the noise level. Oilless Scroll Compressors are rated for 100% duty cycle (oilless piston compressors are rated for 50-70%). The scroll technology is also much quieter (57 dBA vs. 70-85 dBA).
- Medical Air
- Air Brakes
Oilless Scroll Compressors can be supplied as bare pumps, base plate, tank mounted (simplex, duplex and triplex) and stack mounted versions with and without sound enclosures. Mounting multiple scroll compressors can also be a very efficient way of supplying oilless air as each compressor can alternate and turn on/off based on the demand.
More and more fabricators are manufacturing oilless scroll compressors, some of the known brands are: Powerex, Inc., Atlas Copco and Coaire,
