Our company has eight types of machine numbers
NO3.55,4,4.5,5,5.6,6,63.7.1

This fan can be made into two types:right-handed and left-handed.The impellerr otates clockwise and is called a rnght cyclone.Represented by "night',the impeller rotates counterclockwise and iscalleda left cgydone, roprosanted by 'lgft.

The outet posihon of the fan isrepresented by theoutet angle of the casing.and is made into a directional angle.

The transmission mode of the fan is type A.

CHARACTERISTICS

This fan mainly consists of an impaller,casing,air inlet,frame (B3 or B35 modelb),and other components oquipped with a direct connected motor.

Impller:composedof 16 blades with anti oil design,curved front disc and flat rear disc.After dynamic balance correction and aerodynamic performance,it has the characteristics of balanced operation,low wbration,highefficiency,and long service life.

Shell:Welded with steel plates to form a woluteshapedshell.

Air inlet:Made into a whole (al molded),installed on the side of the fan, parallel to the axial direction,The cross-soction of the impeller is in a curved shape,which allows gas to smoothy enter the impeller with minimalloss.

Applicable scenarios

The CF4-82 products are all A type transmission,and the motor is fixed on the side plate of the casing.The suspended bracket or floor bracket design is compact instructure,easytoinstall and place,neat and beautful,and eaay to adjust the outlet。 It adopts flatblades,which can effectively reduce stains on the blades and facilitate deaning and maintenance.The air inlet has a noise reduction device.Ths product is designed specificaly for kitchen smoke eshaust and can also be used for regular ventilation and ventilation.
