The SpiralAIR series of oil‑free scroll compressors is designed to supply ISO Class 0 compressed air in applications where air quality and operational reliability are critical. Scroll compression works without oil, preventing contamination and reducing routine maintenance compared to lubricated technologies.
SpiralAIR units are engineered for efficient operation, combining IE3 motors with a design that avoids unnecessary energy use during unloaded cycles. Optional integrated dryers provide consistently dry compressed air, while low sound levels make these compressors suitable for installation close to the point of use.
For systems with variable air demand, multiscroll configurations adjust output automatically to match actual consumption. This ensures stable pressure control and avoids inefficient operation. The integrated intelligent controller supports performance monitoring, maintenance scheduling and coordinated management of multiple compressors, contributing to continuous and dependable operation.
