Although the idea for a scroll compressor has been around for over 100 years, the technology is actually pretty recent as 40 years ago. As industry continues to advance, so is the need for reliable, clean and oil-free compressed air.
Scroll compressors are ideal in commercial applications that include: medical, pharmaceutical, food, laboratory, textile, electronics, and production facilities. Anywhere quiet, clean air is required, a heavy-duty scroll compressor is the 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) design that compresses air quietly with fewer moving parts and less required maintenance.
How Does a Scroll Compressor Work?
Scroll air compressors use two spiral-shaped scroll pieces to compress air. One scroll is stationary, meaning it's fixed in place and doesn't move, and the other fits inside the stationary scroll and is moved in a tight circular motion without rotating.
The moving scroll presses against the inside of the stationary scroll in such a way that, as it moves in a circular motion, it pushes and traps air into small pockets between the two. The pockets of air continue being moved through the spiral toward the center. As the air moves further toward the center of the spirals, the air pockets become smaller, and the air in those pockets gets compressed.
