Plastic Auxiliary Equipment
A constant-frequency screw air compressor engineered for stable output, efficient direct transmission and dependable long-term industrial service.
Performance Characteristics
Advanced air-end geometry, low-speed operation and a direct-coupled drivetrain deliver reliable compressed air with reduced transmission losses.
The constant-frequency screw air compressor adopts an industry-leading air end with high efficiency and low rotational speed. It uses a third-generation rotor profile with advanced geometric design, ensuring stable performance, high reliability, energy savings, and long service life.
It is equipped with a low-speed motor, offering high stability and 3–5% higher efficiency than similar products. The direct-coupled transmission structure provides 100% transmission efficiency without loss, reduces maintenance costs, allows easy disassembly, and greatly minimizes downtime.
The coaxial integrated structure reduces the use of wear parts while maintaining full transmission efficiency. A low-speed cooling fan is used to extend service life, and the cooler and fan can be disassembled separately for easier maintenance.
Technical Specification
Nine constant-frequency models cover motor powers from 90 to 315 kW and multiple working-pressure options.
