Line
Features: 1. Outline adopt scientific bell design to achieve low noise, strong wind, strong effects of ventilation; 2. Shutter introduce the principles of air downstream and synthetic PVC blinds, antioxidant, light weight, no deformation, flexible open and anti-air back; 3. High strength aliminum magnesium alloy hub, it's light weight, high strength and good tensile; 4. Using the imported bearing, high strength, low noise and durable; 5. High performance energy saving fan motor located in the center of fan, small wind resistance, the structure is more reasonable;
1.Unique push-pull opening system. The push-pull system make sure the shutters could open and close completely. Minimize the wind resistance and greatly improve the operating efficiency. With extended cone design to guarantee that it can achieve high wind pressure, low energy consumption and big air flow in tunnel ventilation condition.
2.Fan blade is special designed for the highest efficiency volume which made of special stainless steel blades punching forming. Large air volume, no deformation, no broken, no dust, attractive and durable.
