Description

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.

Key Advantages:
More Stable
Variable frequency regulation for stable supply pressure

High-accuracy constant-pressure control within ±0.01 MPa

Provides the necessary air volume at the necessary pressure

Set pressure accuracy of 0.01 MPa for maximum energy saving

Reduces pressure fluctuation and improves production stability

More Convenient
Intelligent HMI human-machine interaction interface

Clear status display, simple and convenient operation

Energy-saving mode and remote operation can be switched directly on the display

Fault content displayed on screen for quick troubleshooting

Pressure control mode can be set and changed by touching the screen

Timer operation and alternate operation functions save energy and labor

More Energy Efficient
AirHorse PM VSD screw air compressor saves 33–35% energy compared with ordinary fixed-speed screw air compressors

Standard VSD screw air compressor saves only 10–20%

Energy consumption accounts for about 75% of total life-cycle cost

Fast ROI: in a typical 75 kW example, investment payback is about 1 year

High-Efficiency Permanent Magnet Motor
High-efficiency permanent magnet motor directly connected to the screw male rotor

Direct coaxial integrated transmission structure, transmission rate up to 100%

No gearbox, no coupling, no transmission efficiency loss

NdFeB magnetic material, long service life over 15 years

Polyimide enameled wire, H-class insulation

Allowable temperature rise over 180°C

VFD start: no impulse current, reduced voltage fluctuation, less impact on power grid, longer motor life

Technical Features:
Direct Coaxial Drive
The high-efficiency permanent magnet motor and screw male rotor adopt a direct-driven coaxial integrated transmission structure. Transmission rate reaches 100%. No gearbox, no coupling, no transmission loss.

Advanced Permanent Magnet Motor
NdFeB magnetic material ensures stable magnetic performance and long service life over 15 years. Stator coil uses polyimide enameled wire with H-class insulation. Excellent performance allows temperature rise above 180°C. VFD start reduces impulse current and extends motor life.

High-Efficiency Rotor Profile
Adopts the most advanced 5:6 tooth rotor profile in the industry. Less leakage, large displacement, low speed and low noise.

Compact Motor Design
High-efficiency PM motor maintains high efficiency even at low frequency and low speed. Motor volume is approximately 1/3 of a standard motor.

Reliable Sealing
Specially designed seal structure prevents oil leakage 100%, eliminating oil leakage problems.

Independent Cooling
IC411 motor uses independent air cooling and does not rely on the compressor cooling system. Operation is more stable. IP23 and IP54 protection grades are available.

Intelligent Control System
AirHorse unique closed-loop vector control and PID control

Fast response, safety and reliability

Constant-pressure control system accurate to 0.01 MPa

Superior load tracking and safety

Touch screen for pressure control setting and change

Energy-saving pressure control mode can be easily changed on the display

Timer operation, alternate operation and other energy-saving functions

Compressor running status and various settings can be confirmed on the display

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.
