Durable, efficient and stable air end

Durable, efficient and stable air end

1. The design idea of "large rotor, large bearing, low speed" is adopted to reduce noise and vibration and increase the life and stability of the host.

2. The tooth surface is processed by the German KAPP rotor grinder to create a high-precision rotor, which is the first guarantee of high efficiency and stability of the air end.

3. Adopt a new type of 5: 6 asymmetric rotor tooth shape, high-precision three-coordinate measuring machine for comprehensive measurement, increase the air capacity by 5% -10%
