Short Description

The Airend (screw air end) is the heart of rotary screw air compressors. The entire air compression process takes place inside the airend. Precision-meshed male and female rotors rotate continuously to complete air intake, compression and discharge, delivering steady compressed air. Replace your old airend once it suffers rotor wear, reduced air output, oil leakage, abnormal noise or overheating. No need to buy a whole new compressor, greatly cutting maintenance cost and downtime. Compatible with stationary and portable screw compressors of Atlas Copco, Sullair, Ingersoll Rand and other major brands. Available for aftermarket replacement and OEM assembly.

Key Features

✅ Precisely CNC machined male & female rotors with optimized profile to reduce internal backflow and air leakage. Higher volumetric efficiency, more air output under same power consumption and lower energy cost in long-term operation ✅ Heavy-duty bearings and high-performance shaft seals, anti-fatigue and high-temperature resistant, effectively reduce oil leakage risk, suitable for 24/7 continuous industrial operation ✅ High-strength cast iron housing, stable structure, low vibration and quiet operation, works reliably in factories, mines, construction sites and other harsh environments ✅ Full factory testing: each airend passes air tightness test, pressure test, no-load and full-load running inspection before delivery ✅ Multiple drive options: belt-driven or gear-driven. Covers power range from 7.5kW to 315kW. Oil-injected as standard, oil-free type available on request ✅ Standard mounting interface, direct replacement for original airend, less on-site modification and shorter maintenance downtime

Applications

Replacement for rotary screw air compressors and OEM compressor assembly. Widely used in machinery manufacturing, mining, textile, packaging, chemical industry, road construction, tunnel engineering and other industries requiring continuous stable compressed air.
