Single-unit permanent magnet variable frequency tunnel fan
The series of single-unit permanent magnet variable frequency energy-saving tunnel fans adopt European imported aviation aluminum alloy impellers and permanent magnet variable frequency energy-saving motors. Each fan meets the first-level energy efficiency. Reliable structural design and modular design concept can achieve large flow and ultra-high pressure long-distance ventilation, with significant energy-saving effect. After field practice testing, the fan flow can be accurately adjusted between 1% and 100%, with a steady-state accuracy of 1%, and the output power modularization makes the fan power consumption more accurate.
