Product Features: ① green: no electricity, energy efficient continuous operation, no noise, no spark, with explosion-proof. ② weatherproof features: between the arc-shaped blades, each blade and blade gap, complement each other when the rotating blades of this gap to fill this position, a lot of rain along the section line thrown round, then a small amount of rain along the blade living roof , will not flow in the turbine, while the rotation of the turbine blades of the air gap by flowing, blocking rain from entering. ③ operated device: high-tech standards of ball bearings, which bearing is completely closed, and never self-lubricating, so that it can rotate at a speed of less than 3.2Km breeze. ④ Dust: turbine exhaust fan is 24 hours non-stop forwarding, dust easy attachment, even if the need is also very easy to clean. ⑤ maintenance: Rotary exhaust exhaust no maintenance, no need to replace parts, providing absolute quality, so choose without turbo blower motor is the best protection for investors. ⑥ Lightweight: exhaust turbine installed on the roof of the base even be considered a total weight of about 15Kg / seat, very light, in the design of steel load, you can without consideration. ⑦ lighting: the gap between the blade and the blade into the interior light will thus be increased by 5-10% savings in electricity illumination. ⑧ life: the general life of more than 15 years. ⑨ wide range of applications: just wind speed 0.2m / s in the breeze, or more than 0.5 ℃ indoor and outdoor temperature that can rotate continuously, not only for the flat (oblique) roof, will be adjusted for vertical axis turbines.
