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%

4. All imported quality bearings are used.

Permanent magnetic synchronous motor

Permanent magnetic synchronous motor

1. IP65 protection level, more stable and reliable than IP23 in harsh environments;

2. Oil-cooled design, use lubricating oil to cool the motor, the operating temperature of the motor is more stable, the life is longer, there is no motor axial fan, so there is no loss of energy efficiency of the axial fan;

3. Coaxial design with the main rotor of the air end, without coupling, loss of energy efficiency of the gearbox;

4. Using 38UH magnetic steel material, temperature resistance 180 ℃

Inner rotor fan

Inner rotor fan

1. IP44 cooling fan, Class F insulation;

2. Compared with the outer rotor fan, the inner rotor fan has higher air pressure, more air volume, and better cooling effect;

3. Due to high wind pressure, the cooler and filter are less likely to be blocked
