We import American Airlines' AA7075 super-hard alloy, along with Japanese precision high-pressure forging technology (sigma B 600 mpa), T6 heat treatment, CNC precision machining as well as a dynamic balance check;
The Industrial HVLS fan hub is built by a Japanese senior corporation, which has focused on the precision forging of aluminum alloy for 60 years. Hub and motor cover are put together. The product quality is guaranteed. Ensure the product's tolerance and dynamic balance are as accurate and reliable as the hub of a car.
Chongqing Julai Ventilation Equipment Co., Ltd. is the previous company in China to adopt the combination device of anti-falling disk and top hub cover; that is to ensure we are the outstanding factory that combines upper and lower chassis with fixed fan wing to solve the safety problem (at present, the other manufacturers mostly use the single chassis to reduce cost). At the same time, this reduces the weight of the whole big industrial ceiling fan and improves the motor's efficiency to realize a perfect combination.
The anti-falling disk adopts the lower part, closely connecting with the hub. This improves the current market situation of connecting the anti-falling disk with the frame, with a certain risk of operating.
