High Efficiency Big HVLS Fans Large Industrial Outdoor Ceiling Fan Restaurant

Product Description High Efficiency Industrial Hvls Big Large Industrial Outdoor Ceiling Fan Restaurant A high-volume low-speed fan is a type of mechanical fan greater than 7 feet in diameter.HVLS fans are generally ceiling fans although some are pole mounted.HVLS fans move slowly and distribute large amounts of air at low rotational speed-hence the name "high volume,low speed." Suitable place: Widely used in industrial plants,logistics and warehousing,public places and other high is a perfect solution for high space ventilation and cooling. Advantage: - High efficient air blowing - Low cost and free maintenance - Large application area - 5-Blade design produce more CFM at a Lower RPM - Provide a cool breeze in summer and bring down hear in the winter.  Technical parameters  Model D-500S D-500A D-500B D-700D D-700E Diameters 3.61 meter 4.3 meter 5 meter 6.6 meter 7.1 meter Maximum rev 120RPM 95RPM 80RPM 65RPM 60RPM Maximum power 700 watt 700 watt 700 watt 1500 watt 1500 watt Total weight 16kg 17kg 18kg 47kg 49kg Wind covering space 200㎡-350㎡ 200㎡-350㎡ 200㎡-350㎡ 500㎡-650㎡ 500㎡-650㎡ Mounting height 4-10meter 4-10meter 4-10meter 6-25meter 6-25meter Air volume 10000m³/min 10000m³/min 10000m³/min 18000m³/min 18000m³/min Mounting I-beams / Bar joists / Solid beams Moter type BLDC Brush Less Direct Current Voltage 220V, 50Hz Motor finish Aluminium alloy case Blade numbers 5 blades Applications Factories / Warehouses / Dining halls / Churches / Gyms / Stations / Farms ​ How does it work  The principle behind the extra large ceiling fan is to move a very large amount of air by using large-diameter fan blades rotating at a low speed to break up the stratified air layer. The low speed of the fan makes it more efficient to convert electrical energy into useful laminar flow, rather than generating wasteful turbulence and resistance at higher speeds-which ultimately only generates unwanted heat. These large blades move more air than their smaller ceiling fans, usually 5-20 times, and have the same cooling effect. No other cooling system can be as energy-efficient as a system using HVLS industrial fans. In fact, research shows that companies can reduce or even completely eliminate the use of expensive air conditioning systems through optimized extra large ceiling fan solutions. Some extra large ceiling fan vendors provide 3D thermodynamic models of customer rooms, which proves the effectiveness of extra large ceiling fan as a cost-effective air cooling system.  Features  ※Energy saving: The maximum power of D-500B Big HVLS Fan is 700 watts. ※Big wind: D-500B has a maximum wind volume of 10000m³/min. ※Natural airflow: D-500B Big HVLS Fan can form wind like natural airflow. ※Lightweight fan main body: The total weight of D-500B (main body) is 49kg. ※Built-in PMSM motor: D-500B adopts no PMSM motor and gear box. ※Stepless speed regulation: Our controller is perfectly matched with the fan, and the fan speed can be adjusted steplessly.  Details   Application spaces  Our high efficiency PMSM HVLS fans can applicate in many different spaces: Industial spaces: Manufacturing plants/work shops/warehouses Public spaces: Stations/airports/schools/gyms Commercial spaces: Exhibition halls/malls/hotels/cafes Other spaces:Churchs/health clubs/livestock farms ​ Installations   We can provide a variety of installation methods  according to the building structure of the installation site, whether it is steel structure, concrete structure or truss structure, our high efficiency PMSM HVLS fans can be easily and safely mounted on.
