Description

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.

Key Advantages:
1. More Efficient
High-efficiency air end with German technology

Technology innovation

More efficient

Low noise

Low vibration

Long life

2. More Comfortable
Lower noise

Variable frequency supplies energy according to gas demand without excessive energy loss

Low motor running frequency reduces mechanical rotation noise

No repeated loading/unloading, reducing switching noise

Continuous pressure reduces noise from unstable pressure

3. More Stable
Variable frequency regulation for stable supply pressure

Constant pressure control with pressure variation within ±0.01 MPa

Provides the necessary air volume at the necessary pressure

Set pressure accuracy of 0.01 MPa for maximum energy saving

One-touch switch for changing control pressure settings

Timer operation and alternate operation functions save energy and labor

4. Intelligent Control
Microcomputer control touch screen, simple and convenient operation

Newly developed operation panel, simple and easy to understand

Energy-saving mode and remote operation conversion directly on the panel

Fault display for quick troubleshooting

LED display for compressor status and various settings

AirHorse unique in-line vector control and PID control for fast response, safety and reliability

Exhaust pressure ±0.01 MPa control system with superior load following and safety

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.
