Characteristics and application scope of roof fans

1. Characteristics

① Environmental Protection: No need for electricity. Continuous operation with high efficiency and energy saving, no noise, no sparks, and no explosiveness.

② Wind and rain prevention features: arc-shaped blades, with gaps between each blade. When rotating, the blades complement each other to fill these gaps. A large amount of rainwater is thrown out along the circular pitch line, and a small amount of rainwater also flows onto the roof along the blades, without flowing into the turbine. At the same time, the rotating turbine allows air to flow out through the gaps between the blades, blocking rainwater from entering.

③ Operating device: High tech ball bearings are used, which are completely enclosed and always self-lubricating, allowing them to rotate at speeds below 3.2KW.

④ Dustproof: The turbo exhaust fan runs continuously for 24 hours, making it difficult for dust to adhere, and even if cleaning is required, it is very convenient.

⑤ Maintenance cost: The rotary exhaust fan does not require maintenance or replacement of parts, providing absolute excellent quality. Therefore, choosing a motorless turbine fan is the best guarantee for investors.

⑥ Lightweight: The total weight of the turbo exhaust fan, including the base, on the roof is about 15KG per seat, which is quite lightweight. When designing the steel structure load, it can be ignored.

⑦ Daylighting: There are gaps between the blades, allowing light to enter the room and increase illumination by 5-10%, which can save electricity costs to some extent. ⑧ Lifespan: The general service life is over 15 years.

⑨ Wide applicability: With a breeze speed of only 0.2mls and an indoor outdoor temperature difference of 0.5 ℃ or more, it can rotate continuously. It is not only suitable for flat roofs, but also can adjust the turbine axis to a vertical state on sloping roofs not exceeding 31.5 ℃.

2. Application

① Generate air convection and dissipate hot air.

② Reduce indoor temperature and increase indoor fresh air. Reduce air conditioning load and increase cooling efficiency.

④ Extract moisture, mold, and swallow air from the roof to keep it dry.

⑤ Replace heavy-duty electric exhaust fans, reduce procurement costs, save electricity bills, and minimize noise.

⑥ Suitable for ventilation and air exchange in factories, warehouses, rooftops of buildings, villas, courtyards, flower houses, livestock breeding, mining tunnels, and all roofs, as well as in places with acidic gases.
