The airend is the heart of a rotary screw air compressor, where a pair of precision-machined rotors compress incoming air. Because it runs continuously under load, the airend is a critical component, and a quality replacement or rebuilt unit can restore a compressor to full output without the cost of a new machine.

This collection covers replacement airends and related components for keeping your equipment productive. Learn more about the machines they power in our rotary screw air compressors category, and find additional service components in our compressor parts selection.
