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 bearing no power turbine ventilators, lubrication-free turbine ventilation, 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. Bottom: 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 to produce a way of air flow, so no power-driven, can save costs 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, do 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. Indoor and outdoor pressure difference caused by the large roof turbine ventilation so that the air flow. Third, the impact of high and low temperatures also contributed to the air flow and causes exchange. Window ventilation: external structure attached to the building wall and door between (doors, windows, walls) or on, a certain wind pressure, watertight, airtight, acoustic and other properties in working condition, and to achieve Controlled ventilation means for indoor and outdoor. Can be installed in any window type and location, can be mounted on the window frame, can also be mounted on the sash can also be mounted as the lower part of the windowsills throughout the sill. Window ventilation can be mounted horizontally, vertically mounted; can be installed in the upper portion of the glass to be installed in the lower part of the glass. 800 turbine ventilators | Jincheng turbine ventilation | ventilation consists of Liaocheng Flextronics Flextronics ventilation equipment provided.
