Features of Non-Driven Roof Ventilator
① Environmental Protection: No electricity required, no noise, no sparks, explosion-proof.
② Wind and Rainproof Features: The curved blades have gaps between each one. As they rotate, the blades overlap to fill these gaps, allowing most rain to be thrown out along the circular joints. A small amount of rain flows down the blades to the roof, preventing it from entering the turbine. Simultaneously, the rotating turbine pushes air out through the blade gaps, blocking rain from entering.
③ Operation Unit: Equipped with high-precision ball bearings, these bearings are fully enclosed and self-lubricating, allowing them to rotate even in gentle winds below 3.2 km/h.
④ Dustproof: The turbo exhaust fan runs 24/7, making it difficult for dust to adhere, and cleaning is convenient even when necessary.
⑤ Maintenance Fee: The rotating exhaust fan does not require maintenance or part replacement, offering superior quality.
⑥ Lightweight: The turbo exhaust unit, including the base, weighs approximately 15Kg per unit, making it quite light, which can be disregarded when designing the steel structure's load-bearing capacity.
Lighting: There are gaps between the leaves, allowing light to enter the room, which can increase lighting by 5-10% and save electricity costs.
⑧ Lifespan: Generally, the lifespan exceeds 15 years.
Wide application range: Can continuously rotate with a breeze of only 0.2m/s or a temperature difference of over 0.5℃ between indoor and outdoor, suitable for flat roofs and can adjust the turbine axis to a vertical position on slopes up to 31.5°.
