Axial fan is to promote the use of nature's natural wind speed rotation of the turbine fan 500 without power ventilation, and the use of indoor and outdoor air convection principle, any parallel to the direction of air flow, speed and into the vertical air flow from the bottom up to improve indoor ventilation effect of a device. The fan does not use electricity without power ventilation, no impatient tone, long-term operation. Based on air flow and air flow principles of natural law, is set at the top of the roof of rationalization can quickly exhaust gas indoor hot and dirty, improve the indoor environment. Is the use of natural wind turbine fan and indoor and outdoor temperature difference caused by air convection, rotation of the turbine and thus promote the use of centrifugal force and negative effects of the indoor stale hot air out. Roof ventilators main components: Bracket: made of steel bars imported from Japan, it has a light weight, flexible, does not rust and other properties. Variable angle tube neck: You can change depending on the roof slope angle of the neck, keep in rotation without power ventilators much money, greatly improving efficiency. Bottom: a waterproof substrate stamping turbine head: the wavy blade circular turbo head design is the best result of scientific computing through. Axis: Stainless steel bottom bracket: The United States closed ubc without power roof ventilators bearings, lubrication-free, long life. Axial Fan Installation program, methods and technical measures (1) preparation of construction drawings are familiar with the construction process the arrival of the diffusion tube fan, muffler arrival foundation construction control cabinet position to confirm the detection power supply terminal to confirm the detection handling (2) operating points 1) fan Handling Due to the large equipment, steel size and weight, the application of 8 tons limousine transportation, with 12 tons truck crane for loading and unloading vehicles. In the tunnel according to the actual situation of the tunnel, can pour chain hoist, roll bar and other tools to handle. 500 without power ventilators, Flextronics ventilators (certified), Hubei without power ventilators from Liaocheng Flextronics ventilation equipment Limited.
