Product description

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 adopts a well-known brand high-performance motor. The permanent magnet synchronous motor (PM motor) adopts high-performance permanent magnets, which do not lose magnetism under 200°, and have a service life of up to 15 years.
2. The stator coil adopts the special anti-halation enameled wire for frequency converter, which has excellent insulation performance and longer service life.
3. The motor has a temperature protection function, the motor has a wide range of speed regulation, high precision volume adjustment, and a wide range. Small size, low noise, large overcurrent, significantly improved reliability.
4. Protection class IP55, insulation class F, effectively protect the motor, increase the service life of the motor, and the efficiency is 5%-7% higher than similar products.

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.
