Application

Screw Air Compressor

Material

Stainless Steel

This model represents one of Atlas Copco’s refined air end designs, emphasizing both energy efficiency and long-term reliability.

Precision Rotor Pairing: The male and female rotors are ground to micron-level accuracy, ensuring perfect meshing and low internal leakage.
Optimized Bearing System: The bearing configuration has been improved to better support axial and radial loads, extending service life even under continuous operation.
Thermal Stability: Constructed from high-grade alloy steel, the rotor housing offers excellent heat dissipation and deformation resistance, maintaining tight tolerances in all working conditions.
High Output Efficiency: Internal flow paths have been streamlined to reduce pressure losses, achieving higher air delivery rates at the same motor power level.

Material and Craftsmanship

The air end housing is machined from ductile cast iron using CNC precision boring and honing, ensuring internal surface smoothness and consistent compression efficiency. Each rotor undergoes dynamic balancing and nitriding treatment, improving surface hardness and wear resistance.

All assembly processes are performed under strict ISO-certified conditions, and each unit is subjected to noise, vibration, and air leakage tests before shipment to guarantee flawless performance.

Quality Inspection and Testing

Every KINTON replacement air end follows a multi-stage inspection protocol:

Rotor balance test – ensures smooth rotation and minimal vibration.
Bearing load verification – confirms pressure and load capacity.
Air delivery calibration – checks volumetric efficiency under rated pressure.
Noise and vibration analysis – aligns with Atlas Copco OEM benchmarks.
Final endurance run test – validates temperature and stability under full load.

Only units passing all quality gates are released for packaging and dispatch.
