LGGPM-380 Air-cooled permanent magnet two-stage variable-frequency screw air compressor

LGGPM-380 Air-cooled permanent magnet two-stage variable-frequency screw air compressor 

The LGGPM-380 delivers an ultra-high exhaust capacity of 62 m³/min at 280 kW power, specifically designed for heavy-duty industries such as energy, chemical, and metallurgy. Its dual-stage compression unit works in synergy with a high-efficiency permanent magnet motor, while the IP55 protection rating ensures reliable long-term operation in dusty industrial environments.

1. A 280 kW permanent magnet motor with IP55 protection rating, offering excellent dust and moisture resistance for harsh operating environments such as dusty or high-humidity conditions.

2. The dual-stage design flexibly accommodates both power-frequency and variable-frequency operation, with a compression process that closely resembles isothermal compression, achieving approximately 35% energy savings compared to single-stage oil-injected screw compressors.

3. The variable-frequency fan automatically adjusts its rotational speed based on ambient temperature, reducing thermal stress on the cooler and extending the radiator's service life.

4. The high-efficiency oil separator features a vertical oil separation design, providing ample maintenance space and enabling quick and easy replacement of the oil separation core.

5. Airlink IoT's employee permission management enables multiple users to view and manage enterprise devices in a hierarchical manner, facilitating collaborative operations and maintenance.
