Air Cooling and Ventilation Fucntion with Pmsm Motor Hvls Ceiling Fan

BIG INDUSTRIAL CEILING FANSProduct descriptionThe wind blown from large industrial ceiling fan feels like natural breeze system,the wind speed is just the best cool feeling of human skin. Personnel can feel the temperature difference 5-8 degree, provide personnel a suitable working environment in hot summer,therefore improve the production efficiency. Function of the fan:1-ventilationThe fan improve air exchange in an entire space, it's perfect streamlined design can produces 2-3m/s speed three-dimensional wind, and makes you feel like enjoying the natural breeze system.It promotes the dispersion of smoke, moisture, carbon dioxide and poor air with high specific gravity.So as to improve the quality of working area, create healthy, dry and safe working environment, improve working efficiency.2-convenienceIt is convenience to be operated, control system adopts the latest poleless frequency converter control system.besides of convenience operation, the humanized operation interface also allows you enjoy the beauty of electronic and mechanic achieve the life.3-DehumidificationBecause it can produce large air volume, effectively promote air circulation, so that the moisture is well dispersed, greatly reducing the probability of problems such as bedbugs, fungi and so on.4)beautiful and durableAfter complex surface treatment,the product can avoid the pain of period cleaning,the cost-performance ratio is the highest,the life of each fan can reach more than10 years.4-energy savingThe rated power of the motor on the fan is 1.5KW,each fan can cover 1000 square meter working area,8 hours per day, is just 10 degree power energy consumption,compared to typical small fans and high power consumption air condition, large industrial ceiling fan can be called model of energy saving, can greatly reduce your operation cost.Working principle :Large ceiling fan is a series of products special developed for energy saving,working environment improvement. As we all know,refrigeration is not the only way to achieve the effect of cooling and comfort. The area of a fan could blow is determined by the diameter dimension of it, but has nothing to do with its speed.therefore, the industrial fan with large diameter and low speed combines all these characteristics . After years deeply research and exploration,by integrating oversea advanced aeronautic technology,we Dai sen developed a kind of propeller blades with outstanding performance,it conforms continuous and silent breeze by slowly rotation.The large volume of airflow generated by its unique and high efficient blades push down,thus a nearly perfect propeller exhaust is constructed.      It pushes large volume of airflow to the ground,and constructed certain high level airflow moving horizontally,thus generates a overall air circulation.The advantage is overall ground coverage and three-dimensional circulation of air. The speed of wind generated by"Large industrial ceiling fan"is about 1-3m/s,completely calculated according to the best feeling of cooling when the airflow pass through human skin.too strong airflow makes people feel irritable,a sense of being blown directly,too high speed of airflow also makes people dizzy,only the through the evaporation of skin combines of breeze speed,can beautifies people's feeling of cooling.JUNYI PRODUCT CATALOG AS BELOW:  SeriesModelNumbers of the bladesVoltagePowerDiameterDrive modeMax speedMax air volumeMax coverage area(m²)Fit for installation height(m)Noise levelNet weightFengshen series  (Gearbox motor)DS-7.36220V/380V1.5KW7.3M (24FT)Gearbox motor drive50RPM888000m3/h12007~18≤60db156kgDS-6.76220V/380V1.5KW6.7M (22FT)Gearbox motor drive52RPM822000m3/h10006~15≤60db152kgDS-6.16220V/380V1.5KW6.1M (20FT)Gearbox motor drive55RPM774000m3/h8006~13≤60db147kgDS-5.56220V/380V1.5KW5.5M (18FT)Gearbox motor drive60RPM732000m3/h6005~11≤60db143kgDS-5.06220V/380V1.5KW5.0M (16FT)Gearbox motor drive65RPM690000m3/h4505~9≤60db140kgFengxing series  (PMSM motor)DX-7.36220V1.5KW7.3M (24FT) brushless direct drive50RPM888000m3/h12007~18≤38db106kgDX-6.76220V1.2KW6.7M (22FT) brushless direct drive55RPM822000m3/h10006~15≤38db100kgDX-6.16220V1.0KW6.1M (20FT) brushless direct drive60RPM774000m3/h8006~13≤38db94kgDX-5.56220V0.75KW5.5M (18FT) brushless direct drive65RPM732000m3/h6005~11≤38db72kgDX-5.06220V0.7KW5.0M (16FT) brushless direct drive68RPM690000m3/h4505~9≤38db68kgDX-4.25220V0.6KW4.2M (14FT) brushless direct drive75RPM636000m3/h3004~7≤38db64kgDX-3.65220V0.3KW3.6M (12FT) brushless direct drive90RPM393600m3/h2504~6≤45db42kgDX-3.05220V0.2KW3.0M (10FT) brushless direct drive100RPM331800m3/h2004~5≤45db38kgDX-2.45220V0.15KW2.4M (8FT) brushless direct drive100RPM273000m3/h2004~5≤45db34kg   DS SERIES FANS    DX SERIES FANS  Key component configuration★drive device •Fengshen series fan adopts Taiwan/German gearbox motor•Fengxing series adopts the industry's first non carbon brush, large torque, DC drive motor, replacing the traditional motor speed reducer, realizing high inte
