Ventilation is to prevent accidents resulting in greater damage to persons or property in a large number of harmful gases when the production equipment workshop fortuitous accident or malfunction occurs, may suddenly diffuse or explosive gases and set the exhaust system. Roof ventilation applications necessary measures to ensure that key safety and security of workers in the life of production safety accident Ventilation. Ventilation is to prevent accidents resulting in greater damage to persons or property in a large number of harmful gases when the production equipment workshop fortuitous accident or malfunction occurs, may suddenly diffuse or explosive gases and set the exhaust system. Roof ventilation applications necessary measures to ensure that key safety and security of workers in the life of production safety accident Ventilation. 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, Suqian cowl, 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. 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 generated by air flowing one way, without power roof ventilation cap, so no power drive, roof ventilation cap , 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. 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. No power roof ventilation cap, Flextronics ventilators (certification), the Liaocheng Suqian ventilation cap Ventilation Equipment Co., Ltd. Flextronics. Liaocheng Flextronics ventilation equipment (www.lcwctf.com) (www.lcwctf.com) is an industry leader in Shandong Liaocheng, fans, ventilation equipment, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Flextronics ventilation in leadership with the staff warmly welcome all inquiries negotiations to create Flextronics ventilation a better future.
