4. 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.

5. 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%.

6. All imported quality bearings are used.

Specialized motor for air compressor

1. Large starting torque.

2. Specialized motor for air compressor, imported quality bearings.

3. IE3 high energy efficiency motor, reduce your using cost.

4. Motor design is designed according to 1.2 coefficient.

5. Protection grade IP54, insulation grade F.

Permanent magnetic synchronous motor

1. IP54 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 ceramic plated bearings to completely eliminate the effect of shaft current on bearings.

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

Customized vector inverter

1. Professional customization, perfect match with motor.

2. Fully monitor the parameters of the motor, including the motor temperature, to reduce the risk of the high temperature of the motor.

3. Independent air duct design, strong environmental adaptability.

4. Quick response, the response time is less than 50mS.

5. Large low frequency torque, can output 180% rated torque.

Silent centrifugal fan

1. The whole series adopts centrifugal fan, which is more efficient and more energy-saving.

2. Compared with axial fans, centrifugal fans have higher air pressure, lower noise and more energy saving.

3. Controlled by frequency conversion fan, the oil temperature is constant and the service life of lubricating oil is greatly extended.

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

Three filters

Air filter: the filter area exceeds 150% of the normal requirement, low the inlet pressure loss , and high energy efficiency.

Oil filter: The design of the imported oil filter with enlarged glass fiber material is adopted. The rated processing capacity of the oil filter is ≥1.3 times of the circulating oil volume. The filtering accuracy is high and the durability is good.

Oil separator: imported glass fiber material oil core, good filtration effect, low oil core pressure loss.

Inlet valve

Inlet valve: low flow speed test, low pressure loss, reduce energy consumption.

Minimum pressure check valve: low pressure loss, precise control, ultra-fast repositioning to ensure that the user's air does not return.

Temperature control valve: Mixed flow temperature control valve: The unit is equipped with a mixed flow temperature control valve to ensure that the unit is more convenient to start in a low temperature environment, and to ensure the unit is in the best performance state by controlling the oil supply temperature of the air end.
