Permanent Magnet Variable Frequency - Two-Stage Compression - Screw Air Compressor
Equipped with a two-stage compression structure and an energy-grade-1 permanent magnet variable frequency motor, it delivers superior energy savings compared to standard single-stage air compressors. With a wide power range across the entire series, it ensures stable, durable air supply tailored for long-term continuous production in industrial settings.
Product Details
The magnetic variable-frequency two-stage screw air compressor integrates a two-stage compression host and an energy-efficient permanent magnet synchronous variable-frequency motor—two core technologies for energy savings. It is the preferred upgrade solution for high-energy-consumption factories.
Air undergoes primary compression and intercooling before entering the second stage. By optimizing the pressure ratio, internal rotor leakage is significantly reduced, bringing the compression process closer to isothermal conditions and lowering energy consumption at the source. Equipped with a high-efficiency permanent magnet synchronous motor and an intelligent variable frequency drive system, it automatically adjusts speed based on real-time air demand in the workshop, eliminating no-load waste. Compared to traditional single-stage fixed-frequency compressors, this solution delivers comprehensive energy savings of 15%-30%.
The host features a high-precision, optimized two-stage rotor design. It operates at low speeds, reducing bearing load and exhaust temperature to significantly extend service life. The unit runs quietly with stable air supply pressure and minimal pressure fluctuation. Equipped with an intelligent touch-control system, it monitors pressure, temperature, fuel consumption, and runtime in real time, includes built-in fault warnings, and supports remote monitoring.
Available in air-cooled or water-cooled models with full power coverage. Widely used in continuous production industries such as machining, automotive parts, building materials, chemicals, plastics, textiles, and metallurgy. Designed for uninterrupted operation to help reduce compressor energy costs and achieve energy savings and carbon reduction.
