How a scroll works.

A scroll compressor has only one moving part -the rotating scroll.

The rotating scroll is moved in an elliptical pattern by the electric motor output shaft inside of a corresponding stationary scroll. The elliptical movement pulls air in from the outer edges and efficiently compressor the air charge toward the center of the scroll. This constant displacement pump design reaches 100% volumetric efficiency and ultra-quiet operation with minimal components.

A piston compressor utilizes many components to drive a position in reciprocating motion up and down in the cylinder. As the piston moves down in the cylinder a valve is displaced and allows air to enter, the piston then changes direction and compresses the air charge and expels the majority but not all the charge out the exhaust valve. In theory, the piston compressor can never reach 100 % volumetric efficiency as there will always be a small amount of air left in the cylinder as the piston can never touch the top of the cylinder to due mechanical interference.

The constant change in piston direction, rotating crankshaft, metal on metal of the piston rings and cylinder wall and intake valve fluctuations all contribute to the annoying load compressor noise we are too familiar with.

Why is a scroll better than a piston?

A scroll compressor is truly 100% volumetrically efficient meaning all the air that is pulled into the intake side is compressed and moved through the exhaust side into the tank. The scroll has only one moving part eliminating the constant wear and blow by associated with piston compressors. The scroll rotates in one direction and is designed to run at 100% duty cycle very efficiently and the reason it only requires a 3.3HP motor to drive the scroll to 12 cfm and the best part…. The lack of noise!
