Ventilation Exhaust Fan for Greenhouse and Poultry Farms

ventilation exhaust fan for greenhouse and poultry farms
1. Structure and principle HY series High class fan is mainly made up of blade , Centrifugal Opening Device,motor ,outer frame, protecting nets, supporting frames, shutters . It is made based on aerodynamic, effectively reduce the wind resistance. The major parts are made of galvanized steel sheets and stainless steel sheets. All the products are widely used in various types of buildings as farms ,greenhouses, factory building.Model

Fan blade are advanced through the computer dynamic balance measuring instrument calibration,dynamic balance control in 1g.The fan runningsmoothly,the blower to smooth running,small vibration,low noise,enhances the stability of the whole machine.Fan blade materials are stainless steel,galvanized plate,aluminumalloy three kinds of optional material.
Fan blade is made of Krupp stainless steel by punch forming,no dust,attractive and durable.Special blades shapedesign ensure large air volume,no deformation,no broken,keep air volume same all the way.Thickness 1.2mm,surface finish BA grade.
Moter have domestic brand motor and Siemens motor can be chosen.Motor volatage and frequency can be frequency can be customized Domestic brand motor joining open phase protection device,When the lack of power,can carry out their own power to control;Motor protection grade IP55,insulation class:F.
Centrifugal type open mechanism can guaranteethat the shutters completely open and close,make the shutters opened to reduce resistance,increase the air flow;Close tight,can effectively prevent the outdoor wind,light and dust from entering the house;The first use of high-quality nylon PA66 material,to ensure the servile life of the open mechanism;Centrifugal type open parts are connected,use cooper rivets link,wear resistance,no rust,good flexibility,reduces friction coefficient;Guide rod made of 304 stainless steel,plus special material,ensure the intensity,not rusty,greatly improving the servile life.
Using imported belt,to ensure the servile life.,free maintenance;change the belt type to B instead of A, the service time much longer
In order to facilitate handing,fan on both sides of the fuselage design of the recessed plastic handle,convenient transportation,improvetransport efficiency,and reasonabledesign,beautiful appearance,not to hurt the hand,not easy to damage.
