Refurbished Screw Element Zr90 Zr110zr132 Zr160 Zr250 Zr315 Zr355 Ze4 Ze5

Refurbished Screw Element Zr90 Zr110zr132 Zr160 Zr250 Zr315 Zr355 Ze4 Ze5. Fully disassembled&thoroughly cleaned, with brand-new bearings and seals replaced, rotor clearance precisely reset. Optional rotor recoating service for oil-free airend, repair peeling and worn rotor coating. Dynamic balance calibrated to reduce running vibration and abnormal noise. 100% performance running-test before delivery, meet airflow & pressure requirement, ready-to-install. Great cost-saving versus brand-new airend, shorter lead time. Rotor recoating available to restore rotor surface for oil-free type. Solve common faults: insufficient air output, abnormal noise, internal air leakage. Strict running test after overhaul, stable continuous operation.
