Product features

1. Extremely High Energy Efficiency (Core Advantage)

Permanent Magnet Motor

The rotor is inherently magnetic, requiring no excitation current. The motor achieves IE4/IE5 efficiency, inherently saving energy.

Variable Frequency Drive

Automatically adjusts motor speed based on actual gas usage, achieving "gas production based on gas consumption," completely eliminating energy waste during unloading of power-frequency motors. Overall energy savings typically reach 20%-40%.

2. Stable Operation and Constant Air Pressure

Maintains outlet pressure fluctuations within a very small range (e.g., ±0.1 bar), preventing pressure fluctuations from impacting production processes and equipment and significantly improving air quality.

3. Smooth, Shock-Free Startup

Utilizing variable frequency soft-start, the starting current is less than twice the rated current, minimizing impact on the power grid and electrical system, extending equipment life.

4. Lower Noise

At low gas usage, the motor speed decreases, significantly reducing operating noise and improving the working environment.

5. Higher Reliability

Avoiding frequent loading/unloading cycles reduces impact on the motor, screw element, and solenoid valve, resulting in less wear.
