Although the theory for a screw jack china scroll compressor has been around for over a century, the technology is actually pretty recent as 40 years ago. As the market continues to advance, so is the dependence on reliable, clean and oil-free compressed atmosphere. Scroll compressors are ideal in industrial applications that include: medical, pharmaceutical, food, laboratory, textile, electronic devices, and production facilities.
Anywhere quiet, climate is necessary, a heavy-duty scroll compressor is the only way to go. They come in a wide variety of sizes, up to 30 HP, which can produce as much as 86 CFM! Scroll compressors 
utilize a very innovative (spiral) style that compresses air quietly with fewer moving parts and less required maintenance.
Scroll air compressors use two spiral-shaped scroll pieces to compress air. One scroll is definitely stationary, meaning it’s fixed set up and doesn’t move, and the other fits in the stationary scroll and is usually moved in a tight circular movement without rotating. The moving scroll presses against the inside of the stationary scroll in such a way that, as it techniques in a circular motion, it pushes and traps air flow into small pockets between the two.
The pockets of air remain moved through the spiral toward the guts. As the air movements further toward the guts of the spirals, the surroundings pockets become smaller, and the surroundings in those pockets gets compressed.
