Atlas Copco Air End 1616679281-1616747281 O.F.S. I 41 By Air Compressors Parts China Genuine Supplier

1. Using the standard Atlas Copco profile (SAP), the rotor adopts a 4/6 tooth combination, and the rotor diameters are equal. Compared with the 5/6 tooth (Sigma) or 4/5 tooth (Cyclon) combination, the female rotor has higher stiffness , so it is not easy to deform and the internal leakage loss is small.

2. SAP profile: due to compression force, it contacts the trailing edge of the tooth side. The gap between the rotor seal lines is small. The air outlet hole at the exhaust end is small (the leakage triangle is small). Small internal leaks and losses. Higher internal pressure ratio (10bar). Improved efficiency, especially in 10 and 13 bar models, with larger rotor diameter and low tip-speed.

3. Effective, reliable and long-life oil seals and air seals that have been continuously improved and tested by time for more than 40 years. It is composed of an oil seal C with a reverse thread and a second stainless steel air seal B. These oil seals and air seals maintain a small gap but do not contact the shaft. Their sealing efficiency, reliability and lifespan are far better than ordinary labyrinth seals or mechanical seals. A.C. There is a leakage hole E between the oil seal and the air seal, which can still provide compressed air in case the seal is damaged.

4. Gearbox: It can reduce more energy consumption and cost. The axial force generated by the gear offsets the axial force acting on the male rotor. Direct drive does not have this advantage.
