Product description

AIR END

AIR END

1. Adopts the intermational top-level third-generation asymmetric wire twin-screw air end, adheres to the exquisite manufacturing process, adopts the peak high eficiency low pressure, high-fficiency tooth shape and the axial air inlet design.
2. Optimized flow channel design, with a large rotor, low speed and high eficiency. Increased energy eficiency by 5% -15% compared to the second generation.
3. Uses Swedish SKF heavy-duty bearings, doubl-lip lip shaft seal, durable and reliable. The bearing design life is 80,000-100,000 hours and the air end design life is about 200,000 hours.

MOTOR

1. The motor uses high-performance motors of well-known brands. Permanent magnet synchronous motors (PM motors) use high-performance NdFeB permanentmagnets which will not lose magnetism under 200. and its service life reaches as long as 15 years.
2. The stator coil uses the frequency converter special halo proof enameled wire, theinsulation is outstanding and the service life is longer.
3. The motor has the function of temperature protection. It also has a wide range of motor speed regulation, high precision and wide range of volume regulation. The reliability is significantly improved with small size, low noise and large excess current.
4. Protection grade IP55, insulation grade F, efectively protects the motor and increases the serice life of the motor, the eficiency is 5% 7% higher than similar products.

MOTOR
INTAKE VALVE

INTAKE VALVE

1. Intake valve is the core component to control the air intake of the air compressor.
2. Adopting the world famous brand air intake valve, it can automatically adjust theair volume by 0-100% according to the requirement of the system air quantity. It promises small pressure loss, stable action and long life consequently reduced operating costs.

HEAT EXHANGER

1. The heat exchanger uses high-quality raw materials and a unique intemal channel design, which increases the heat exchange area and can effectively dissipate heat for the air compressor.
2. The inner wall of the heat exchanger is treated with corrosion protection to increase the service life of the heat exchanger and increase the heat transfer effect.
3. The radiator has passed the strict factory test, and the quality is reliable, which efetively prevents the high temperature of the air compressor and increases the service life of the machine.
