Product Features
1. This series of ventilators is designed based on the three-dimensional flow theory of impellers, with meticulously engineered test data to ensure excellent aerodynamic performance. They feature low noise, high efficiency, minimal vibration, and low energy consumption.
2. The ventilator comprises an explosion-proof motor, impeller, air duct, and protective cover.
3. Suitable for ventilation and exhaust applications; can also be installed in series within short exhaust ducts to increase duct pressure.
4. Cable wiring is standard. For steel pipe wiring, specify this requirement when placing an order.
