HVLS Large Industrial Ceiling Fans Manufacturer

-----Performance----- 1. Large Coverage Blade length maximum24FT, Vansefans unique 3 degrees upward, 30% coverage rate. Effective coverage is more than 1,500 square meters. 2. Large Volume No Empty Recycle Vanse HVLS fans variable streamlined cross section–according to aerodynamics equal chord length theory ,the blade gradually narrowed and thinned from root to tip until the tail then widened, root to tail width is 29.8-19.2cm. Make sure the air uniform along the length direction, even cover middle area. 3. Comfortable Tridimensional Natural Wind The wind generated by Vanse large ceiling fan simulates the natural wind, three-dimensional air supply, covering the whole body to maximize the sweat evaporation. Make the body 4-7 degree temperature difference, forming similar nature breeze system. But traditional high speed fan blowing directly is very uncomfortable, not only the speed is too high, but also make the body temperature plummets, this will bring health problems. 4. Install Save Space Vanse industrial ceiling fans installed in the upper space 4.5 meters above the ground, fixed on the roof structure beam by clip. It will not affect any ground work, safe and reliable. 5. Economic Energy Saving Adopts aerodynamics principle, our industrial fan can cover more than 1500 square meters with only 1.5KW motor 6. Ten Security Guarantee Vansefan has unique ten security guarantees, effectively ensure the user safety. -----Configuration----- Ⅰ. Power: PSMS Motor 1. Small size: 1/3 of geared motor, applicable for more places. 2. Low noise: less 40% than geared motor. 3. Fully enclosed, maintenance free. Ⅱ. Controller: Vector Converter 1. Start steady: Motor vector algorithm and current suppression to achieve. 2. No noise: up to 16KHZ, no noise during speed up, slow down, and running. 3. Failure protection: 25fail-safe protections (over current,over voltage,under voltage phase loss,overload,etc.) Ⅲ. Fan Blade *patent: Variable Cross-section Streamlined Blade 1. 5 pieces of 1.5mm thick 5052 aero-grade aluminum plate are adopted, which can withstand more than 3 tons of tension and will not crack when impact. 2. Variable cross-section streamlined blade: fan blade gradually narrows from root to tip and thins to the tail then widens,wind resistance is small, air volume is more uniform. Ⅳ. Connection *patent: Structural Connection System 1. Petiole and chassis are connected by trapezoidal ladder clamping groove, and the structure is stressed as a whole without the risk of bolt fracture. 2. Petiole and blade adopt flexible shock absorber to release high-frequency vibration and ensure that the bolts are not impacted. Ⅴ. Chassis Assembly: Integrated chassis 7075 aero-grade aluminum material is made by CNC lathe machining with precision process, the shape remains totally same, well appearance to ensure the best mechanical performance of chassis.
