ventilation fan:
9A Series of ventilation fan is made up of frame,wind set,fan blade,motor,
drive mechanism,bracing frame,shutter,protective net etc.The motor drives the fan blades,
air flow exhaust the air in the house and puts fresh air into the house and then ventilates the air in the house .
When the fan stops working ,the shutter close 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.
9
series of ventilation fan ,the overall performance is much better,the structure is more reasonable .
Utilizing centrifugal principle and hammer made shutter open
,close system can ensure the shutter open up ,
then make the fan running at high efficiency all the time .Then it reduces the consumption of energy and enhanced the air flow .
When the fan stopped, 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 easy to maintain..
9FJ/B series of products with its unique design makes the running efficiency
and air flow much higher than other like products.
