■ Descriptions
Exhaust fan is the use of air convection,negative pressure ventilation to achieve the purpose of cooling.It inhale fresh air, and then put the hot gas is mandatory to outside.It make indoor keep well ventilated.Cooling ventilation effect can reach 90%-97%.
►Product advantage
1) Energy saving
Take 54 inch type of fan for example, the power of general type of fan is 1100w or 1500w, but our fan is 750w. So if you take use of it, you just need pay half of the cost.
2) Large air output
Take 54 inch type of fan for example, the measured air volume of better quality type of fan is about 40000 cubic meters, but our fan can reach to 64990 cubic meters.
3) Lower noise
Our perfect design concept and material decrease the noise, and it can work steady.
4) Long lifetime
The fan casing and motor stents were produced by the material of glass fiber reinforced plastic which resists corrosion and airslake. The material of shutter is PVC, also resists corrosion and airslake. Fan blade is made of nylon and fiber material, and has better sturdiness and flexibility.
5) Low failure rate
Because of the electric motor and fan blade connected directly, it has no belts, belt pulley, bearing and other damageable rotating components. And the rotation speed of our motor is just 450rpm, so its failure rate is very low. However, the rotation speed of conventional motor always need 1450rpm for same air volume output.
