Poultryhouse exhaust fan

Series 9FJ-A/B agriculture and animal husbandry fan is made up of frame,wind set,fan blade,motor,drive mechanism,bracing frame,shutter,protective net etc. the motor drives the fan blade,air flow exhausts the air in the house and puts fresh air into the house and then ventilates the air in the house.when the fan is running,the shutter opens,when the fan stops working,the shutter closes itself,which prevents the dusts going into the fan and avoids the detrimental of rain,snow or wind.If automatic temperature control system is assembled, the products will be operated automatically. Series 9FJ-A/B agriculture and animal husbandry fan on the bases of the fully complied with type 9FJ-A,the overall performance is much better,the structure is more reasonable. Utilizing centrifugal principle made shutter open-close system can ensure the shutter open up.then make the fan running at high efficiency all the time,then it reduced the consumption of energy and enhanceed the air flow, when the fan stoped, the shutter closes more closely at the control of steel spring, which prevents any air leak, the motor is seted in the top of the fan, which is more safe and convenient to maintain and clean. Series 9FJ-B products with its unique design makes the running efficiency and air flow much higher than other like products.
