1. This series of ventilators is designed based on the three-dimensional flow theory of impeller mechanics, with meticulously engineered test data ensuring excellent aerodynamic performance. They feature low noise, high efficiency, minimal vibration, and low energy consumption.
2. The product consists of an explosion-proof motor, impeller, air duct, protective cover, rain cover, gravity-type check valve, and insect screen.
3. Rain covers are available in 45°, 60°, or 90° configurations. Gravity-operated check valves ensure workshop isolation from outdoor air when the fan is off.
4. Installation type: Wall-mounted.
5. Cable or steel pipe wiring.
