1. Large air volume design, ventilation capacity 43000-44500m3/h Motor 0.75kw only low-energy, low operating costs.
2. Special motor die cast aluminum housing, protection class reached its highest level IP5.4, F class insulation, both overloadand phase loss protection.
3. Shell is made of FRP material, light weight, insulation, no rust, no aging, moisture, acid, durable, long service life. Use of the unique shape of the flow channel design, waterproof, rainproof. Oil heating mold machine pressed fiberglass shell, highstrength, corrosion resistance, long life and metal excessive resonance.
4. Blades are made by thick FRP pressure molding machine, high strength, non-corrosive, never deformation. With anti-corrosion and low noise characteristics.
5. Special motor, direct-type structure (different from the traditional belt drive) offers features that simplify configuration and reduce maintenance costs.
6. Air downstream principle shutters, no power, no switch, and can effectively prevent rainwater intrusion, specification installation does not occupy space, without air duct, it can be installed in any place.
7, Fasteners: All screws are made of stainless steel to prevent corrosion and loosening.
