Roof axial fans are divided into several main components are a few: turbo head: the wavy circular turbine blade head design. Axis: High quality stainless steel bottom bracket: a fully enclosed ubc bearings, lubrication-free, long life. Bracket: made of imported steel bars. Variable angle tube neck: can change depending on the roof slope angle of the neck, to stay in the rotation, greatly improving efficiency. Floor: One way a metal forming machine waterproof board fire cabinet exhaust flow is based on the principles of the natural environment of the local pressure difference and gas generated by the flow of air no power turbine ventilators, so no power-driven, cost savings and Energy. Outdoor when no wind, rely on a stable temperature difference between indoor and outdoor air exchange flow is achieved. When a large outdoor natural wind velocity, time, will be able to rely on outside pressure to ensure the effective air exchange. Respiratory window or outside the window with building the perfect combination of roof turbine ventilators, does not affect the overall appearance. Fire cabinet ventilation exhaust fan in the same area which ventilation effect depends on the following factors: first, the size of indoor and outdoor temperature. To promote the flow of gas to drive air pressure flow. Second, natural wind outside the room size. Resulting in a large indoor and outdoor pressure differences, so that the air flow. Third, the impact of high and low temperatures also contributed to the air flow and causes exchange. Fire ventilator fan connection duct should have a separate import and export support, plus the weight of the pipe is not allowed on the blower parts, turbine installation should pay attention to the horizontal position of the automatic turbo fan ventilation, the fan and the foundation of the joint surface and connecting the air pipe should be adjusted so that the natural fit, not be forced to join.
