Product Description
Product Application
Roof ventilator when ventilation can prevent rain and snow, insects, noise, roof ventilator sand into the interior; Ventilation is not restricted by time, season, even if without, sleep indoors can be at ease use, there will be no thieves, string hall wind invasion; Deflection up can't make into indoor air flow way the wind blows and items; Compared with a window ventilated, can reduce indoor heat loss, because of no power (electric) drive, energy saving; Due to the structure design more reasonable roof ventilator, its quality is also made of steel, so the basic don't need any repairs, its life and door window is the same.

Main Features
1.Weather-proof features: circular blades, each leaf and leaf there is gap between, when rotating blades complement each other to fill this gap, throw a lot of rain delay with round section line, small leaves and the rain was delayed in the piece on the roof, not into the turbine, at the same time, rotating turbine make the air by the blade clearance flow, keep the rain out.
2.Running device: using high technology level of ball bearing, the bearing is completely closed, and will never self lubrication, enable it to rotate under below 3.2 Km per hour breezes.
3.Dust: turbine exhaust fan is 24 hours don't halt, dust adhesion not easily, even if is also easy to clean.
4.Does not need maintenance: rotary exhaust exhaust maintenance free, also do not need to change parts, provide very good quality, so no motor turbine fan is the best choice.
5.Light weight: the turbine exhaust even the base shall be installed on the roof to calculate the total weight about 15 kg/seat, fairly light, in the design of steel structure under load, can need not consider.
6.Daylighting is good: a gap between blade and blade light will enter indoor, can increase the illuminance is 5-10% in power savings.
7.Long life: general life in more than 15 years.
