45 kW – The latest-generation SED+ series permanent-magnet two-stage variable-frequency screw air compressor

The SED+ series 45 kW two-stage variable-frequency screw air compressor features an integrated intake control valve and an IE5 high-efficiency motor, delivering 35% higher energy efficiency compared to standard industrial-frequency models. Paired with Ultra-Web high-precision filters and AirLink IoT smart management, it serves as a reliable upgrade solution for air supply systems in small and medium-sized manufacturing enterprises.

 1. The integrated intake control valve automatically regulates the air supply volume, enabling real-time control during the machine's light-load startup, load operation, and unloading processes.

2. The IE5 high-efficiency motor features a two-stage compression architecture, delivering 35% higher power-saving efficiency compared to standard industrial-frequency motors and offering significant long-term operational cost advantages.

3. Ultra-Web high-precision air filter featuring imported polymer filter media, achieving a filtration accuracy of 99.99% and delivering clean compressed air.

4. The dual-inverter noise reduction technology, combined with an IP55 protection rating, ensures quiet operation at 72 dB and stable performance even in dusty or humid environments.

5. Integrated with the AirLink IoT smart platform, it delivers real-time fault warning alerts for early detection and resolution of issues.
