AirHorse BPM Series PM VSD Screw Air Compressor – Permanent Magnet Variable Speed Rotary Screw Compressor
Short Description:
AirHorse BPM series PM VSD screw air compressor is a high-efficiency permanent magnet variable speed rotary screw compressor designed for energy-saving industrial compressed air supply. Equipped with a high-efficiency PM motor, direct coaxial drive, closed-loop vector control and PID constant-pressure control, it achieves ±0.01 MPa pressure accuracy and saves 33–35% energy compared with fixed-speed screw air compressors. Available from 3 kW to 75 kW, with 0.8 MPa and 1.0 MPa working pressure options.
Product Overview:
AirHorse BPM series PM VSD screw air compressor adopts advanced variable frequency speed control to match air demand precisely. It eliminates the energy loss caused by traditional inlet valve throttling and repeated loading/unloading. The system provides the required air volume at the required pressure through high-accuracy constant-pressure control.
The BPM series features an intelligent HMI human-machine interface, simple touch-screen operation, fault display, energy-saving mode, remote operation and timer/alternate running functions. It is ideal for factories and industrial users looking for stable pressure, low noise, high reliability and fast return on investment.

Energy-Saving Comparison:
When purchasing an air compressor, traditional cost (purchase cost + maintenance cost) accounts for only 25% of total cost, while energy consumption accounts for 75%.
Ordinary VSD screw air compressor saves 10–20% energy compared with fixed-speed screw air compressor.
AirHorse PM VSD screw air compressor saves 33–35% energy compared with fixed-speed screw air compressor.
Example:
A 75 kW standard screw air compressor runs 8,000 hours per year. Electricity price: ¥0.62/kWh. Annual electricity cost: 75 kW × 8,000 h × 0.62 = ¥372,000.
AirHorse 75 kW PM VSD screw air compressor saves about 35% energy per year: ¥372,000 × 35% = ¥130,200.
Return on investment (ROI): about 1 year.
