[Sunshine] Jiangsu roof ventilation roof ventilation roof ventilation price production technology and construction: roof ventilators uses a unique variable angle diameter, as long as the angle between 0 and 22.5 civilian aspects of various industrial plants: roof ventilators for residents district flue outlet, solved due to high winds and low pressure air is sometimes caused by intrusion, avoid home filled with fumes and odors. According to the project examples prove even when the wind speed at 200 km / h, 200 mm rainfall in / hr, ventilators still intact operation, no water leakage Edit this paragraph 500, 600 construction 500, 600 automatic ventilator roof structure (1) Waterproof bottom: 500 ventilator waterproof floor size is 750mm * 750mm, 600-type ventilator waterproof floor size is 900mm * 900mm, thickness: stainless steel 0.6mm, color steel plate 0.8mm. (2) variable angle diameter : 500 ventilators variable angle diameter diameter 50cm, height 20cm; 600-type ventilators corner diameter diameter 60cm, height 25cm, 500-and 600 ventilator is as a basis for the classification. Stainless steel ventilation with variable angle diameter thickness of 0.6mm,, color steel ventilation with variable angle diameter of 0.8mm. (3) Turbine head: There are 32 turbine blade head composed of 500 ventilator blade width of 6.5cm, 600 Ventilation blades with a width of 8.31cm. Blade thickness: 500 ventilator blade thickness: stainless steel ventilation 0.31mm, color steel ventilators 0.4mm. (4) Bracket: 500 and 600 ventilator has two brackets, wherein the upper bracket is aluminum bracket, lower bracket nylon bracket. The thickness of the aluminum frame 4mm, with a strong anti-corrosion, high strength and flexibility, a person standing on the foot stand, step on constantly. (5) axis: ventilator power system, there are two main bearings, an iron pillar and a rotor component, is a closed structure, the ventilation in the case of maintenance-free use for many years.
