75KW VSD Rotary Screw Air Compressor

This world-class screw air-end features high efficiency and low speed. Its rotor utilizes a third-generation 5:6 tooth profile, the world's most optimized tooth profile. It is characterized by a compact footprint, low noise (only 67 decibels), low energy consumption, low maintenance costs, and excellent reliability and availability. The permanent magnet motor and compressor main motor utilize an integrated, direct-shaft connection for a more compact design and 100% transmission efficiency. The motor is bearingless, and the permanent magnet rotor is mounted directly on the convex shaft of the convex rotor, eliminating motor bearing failure points.

This high-efficiency permanent magnet motor uses magnetic fields and the magnetic force generated by the AC voltage and stator coils to drive the rotor, achieving low speed and high efficiency. Compared to traditional frequency-controlled motors, it offers even better energy savings.

The permanent magnet synchronous motor utilizes high-performance neodymium iron boron permanent magnets, which resist demagnetization even at temperatures of 120°C.

The stator coil utilizes corona-resistant enameled wire specifically designed for inverters, offering excellent insulation and a longer service life.

The synchronous motor has fast response and excellent exhaust response speed.

Soft-start is enabled, preventing the motor current from exceeding full load during operation, significantly reducing impact on power grid equipment and preventing damage to power-consuming devices.

The advanced microcomputer-controlled drive system provides intelligent control, variable speed control, automatic air flow adjustment, load start, and soft start functions, eliminating current spikes and extending component life, significantly improving system stability and reliability.

The rotary oil filter utilizes high-end aviation-grade materials, boasting 20% higher efficiency than traditional filter elements, effectively extending the normal service life of the main unit.

Featuring a high dust holding capacity and low flow resistance design, it removes up to 99.5% of fine solid particles from the air, ensuring the proper operation and economical service life of all system components.

The design features an extra-large heat exchange area to improve cooling efficiency and effectively prevent overheating. The interior is treated with an anti-corrosion treatment to withstand harsh operating conditions and extend service life.
