AirHorse EPM Series Permanent Magnet Inverter Screw Air Compressor
Short Description:
AirHorse EPM series permanent magnet inverter screw air compressor is a high-efficiency, energy-saving VSD air compressor equipped with IE5 permanent magnet synchronous motor (PMSM), advanced vector control and PID constant-pressure control. It delivers ±0.01 MPa precise pressure control, reduces energy consumption by 33–35% compared with ordinary fixed-speed compressors, and ensures stable, low-noise and reliable operation. Widely exported to over 100 countries and regions.
Product Overview:
Energy saving and environmental protection are new technological challenges for today’s industrial products and have become a major mission of the air compressor industry in the 21st century. To meet the needs of the times and lead its peers, Guangzhou AirHorse Compressor takes meeting customers’ demands as the core of technology development and continuously develops advanced leading screw compressors.
AirHorse EPM series permanent magnet inverter screw air compressors are exported to more than 100 countries and regions. They offer reliable operation, low noise, long life, high efficiency and outstanding energy savings.
The EPM series uses variable frequency speed control to supply energy according to actual air demand, avoiding excessive energy loss. The motor runs at low frequency, reducing mechanical rotation noise. Because the inverter adjusts motor speed, there is no repeated loading and unloading, which reduces noise caused by frequent switching and maintains continuous pressure to minimize pressure fluctuation noise.

5. AirHorse Permanent Magnet Synchronous Motor
Super-level energy efficiency, more energy efficient
PMSM tested by national energy efficiency laboratory, exceeding national first-class energy efficiency standards
High protection grade design: IP54, preventing failures caused by bad environments
Compared with asynchronous induction motor, PMSM maintains over 95% efficiency and higher power factor at different speeds
At low speed, PMSM efficiency is 20% higher than traditional asynchronous motor
Energy-Saving Effect Comparison:
When buying an air compressor, traditional costs (purchase cost + maintenance cost) account for only 25% of total cost, while energy consumption accounts for 75%.
Ordinary (inverter) screw air compressor saves 10–20% energy compared with ordinary (power frequency) screw air compressor.
AirHorse EPM frequency conversion screw air compressor saves 33–35% energy compared with ordinary (power frequency) screw air compressor.
Example:
A 75 kW ordinary screw air compressor runs 8,000 hours a year, electricity price ¥0.62/kWh. Annual electricity cost: 75 kW × 8,000 h × 0.62 = ¥372,000.
AirHorse EPM 75 kW screw air compressor saves about 35% energy per year: ¥372,000 × 35% = ¥130,200.
Return on investment (ROI): about 1 year.
