Fonctionnement

Single-screw water-lubricated oil-free compression: the compressor's own pressure differential continuously injects purified water into the compression chamber and bearings during compression. Water forms a film between the rotor, star wheel, and casing, providing simultaneous lubrication, gas sealing, and cooling. The star wheel is directly driven by the main rotor. Lubricating water absorbs compression heat, keeping main-unit running temperature ≤ 50°C. The system automatically flushes with fresh water every 200 hours to maintain minimum calcium content and prevent scale. A variable-frequency drive modulates rotor speed according to air demand; direct coupling eliminates mechanical transmission losses.
