Rotary Screw Air Compressor Types
An overview of the rotary screw compressor types OPPAIR builds, arranged so the differences are visible rather than buried in a specification sheet: single-stage and two-stage, oil-injected and oil-free water-lubricated, fixed-speed and permanent-magnet variable-speed, air-cooled and water-cooled. Two-stage machines split compression across two rotors for better efficiency at higher pressures, while PM VSD units vary speed to follow demand. Reading across this group is the quickest way to decide which architecture suits your plant before looking at individual models. Tell us your working pressure, required flow and how much your demand varies, and we will recommend the type rather than the nearest catalogue number.
For selection criteria, service points and site requirements, read our fixed-speed vs PM VSD screw air compressors.
