Oil-Less Scroll Airend

Oil-free Scroll Air End

Our Oil-free Scroll Air Ends are more than just components; they are guardians of air quality and reliability, serving critical industrial needs. Whether your focus is on maintaining the utmost air purity for sensitive processes or adhering to stringent environmental standards, Scala's Oil-free Scroll Air Ends stand as paragons of excellence.

Our Oil-free Scroll Air Ends are not just products, but solutions sculpted for industries where oil-free and untainted air is non-negotiable. Available in power variations of 2.2kW, 3.0kW, 3.7kW, 5.5kW and 7.5kW, they assure unwavering performance under both 8 and 10 bar pressures.

Applications

Oil-free scroll air-end technology is widely used in applications where clean, contaminant-free compressed air is critical. Since oil-free scroll compressors do not use oil for lubrication or sealing, they are ideal for industries that require high air purity. The key applications of oil-free scroll air-end technology includes Medical and Healthcare, Food and Beverage, Pharmaceuticals, Electronics and Semiconductor Manufacturing, Chemical and Petrochemical, Aerospace, Environmental and Water Treatment, etc.

Structure of Scroll Airend

Scroll air-end consists of several critical parts that work together to compress gas efficiently. Below is a detailed breakdown of Scala brand airend.
Structure of Scroll Airend

Working Principle

Basic Principle:
A scroll air-end consists of two spiral-shaped scrolls: one fixed scroll (stationary) and one orbiting scroll (movable). The orbiting scroll moves in a small circular motion (without rotating) relative to the fixed scroll, creating a series of gas pockets between the two scrolls. As the orbiting scroll moves, these pockets progressively decrease in volume, compressing the gas trapped inside.

Compression Process:
Intake Phase: Gas enters the outer pockets of the scrolls through the intake port.
Compression Phase: The gas pockets move toward the center of the scrolls, reducing in volume and increasing in pressure.
Discharge Phase: The compressed gas is discharged through the center outlet port.
