2021 Good Quality Screw Drive Compressor - Oil less Screw Air Compressor Machine For Sale – OPPAIR

Fixed Speed Screw Air Compressor

Permanent Magnet Frequency Conversion Series

Product description

1. The OPPAIR Oil less screw air compressor has high reliability, few parts, no wearing parts, reliable operation and long service life. Generally, the design life of the main screw head is 30 years.
2. The oil less screw air compressor is easy to operate and maintain, with a high degree of automation, and operators can achieve unattended operation without long-term professional training.
3. The power balance is good, there is no unbalanced inertial force, the high-speed operation is stable, and the basic operation is realized.
4. Strong adaptability, with the characteristics of forced gas transmission, the volume flow is almost not affected by the exhaust pressure, and it can maintain high efficiency under a wide range of working conditions. It is suitable for a variety of working conditions, so it is easy to finalize mass production.
5. In the multi-phase hybrid transmission, there is actually a gap between the rotor tooth surfaces, so it can withstand liquid impact, and can pressurize liquid gas, dust gas, easily polymerized gas, etc.
6. The flow rate of the slide valve is adjusted without backflow, which can effectively reduce energy consumption.

SMART CONTROLLER

1. Adopts PLC multilanguage control system, beautiful and intuitive interface, easy to operate function, operators can quickly and easily adjust the compressor.
2. 14 protection functions such as overload protection, short circuit protection, reverse protection, low temperature protection, high voltage protection, etc. to fully protect the unit.
3. The advanced microcomputer control drive system realizes itelligent control, air volume variable speed control, automatic adjustment of load start and soft start. Inelligent dynamic control, dynamic display of the working status of each component of the compressor, visual pressure, temperature, current working curve, etc.
4. Large memory and equipped with printer interface; It can use computer remote monitoring or multiple linkage control between air compressors.

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.

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.
