Here is how it works: Scroll compressors compress a specific amount of air into a continuously decreasing volume. They consist of stator spiral that is fixed in a housing and a motor-driven eccentric, orbiting spiral.
These spirals form air pockets with a gradually varying volume, which means that the air pockets they form increase when air enters them and then decrease to generate compressed air. The alignment of the screws provides the scroll elements with radial stability.
The process minimizes leakage because the pressure difference in the air pockets is lower than that between the inlet and the outlet.
A compression cycle takes 2.5 turns, which virtually guarantees a constant and pulsation-free air flow. That is also the reason why scroll compressors are relatively silent.
There is an abundance of applications for quiet and energy-efficient compressors that produce absolutely clean air.
Take the SF series from Atlas Copco, which has been a leader in this field for more than 60 years.
Its unique characteristics make it ideal for many manufacturing processes for which clean, oil-free compressed air is a prerequisite. That is why the SF is the preferred choice for sensitive indoor environments, like hospitals but also labs, breweries, bakeries, dairy farms, electronics manufacturing, and even lens production.
