The type 4-72 centrifugal fan is a kind of high efficiency and energy saving centrifugal fan. The airfoil blade, curved impeller front plate and
The cone-shaped curved inlet collector gives the fan excellent aerodynamic performance. It's been used in China's economy for years
IC structure.
In the 4-72 fan, the 2.8 ~ 6A fan is mainly composed of the impeller, the housing, the air intake and the motor. No 8-10c and D fans also have dri
VE group, pulley or coupling.
The rotation direction of 4-72 fan can be divided into right turn and left turn. From the front view of the motor end, im
Peller spins clockwise. It is called a right rotating fan, denoted by "right". A counter-clockwise rotation is called a left-rotating fan, i.e
Denote by "left". The rotation direction of the fan should be indicated in the order form.
4-72 The exit position of the fan is indicated by the exit Angle of the housing. No 2.8 ~ 6A all made one when leaving
The factory. The user can install according to the desired outlet position. No need to specify when ordering. adjust
2.8 The position of No. 1 air outlet is 0°~225°, and the interval is 45°. The adjustment range for the position of air outlet 3.2-6A is 0
° to 225° with an interval of 22.5°. The exit positions of numbers L8 to 12 are 0° to 225°, the interval is 45°, and should be marked
When ed. The position of No. 16-20 air outlet has three fixed angles of 0°, 90°, and 180°, which cannot be adjusted during air intake
tallation, and indicate it when ordering.
The 4-72 fan has four driving modes: A, B, C and D. Type A is a direct drive between the impeller and the motor, type B is a belt drive,
The belt pulley is located in the middle of the two bearings, type C is a belt drive, the belt pulley is cantilevered outside the bearing, and type D is
It is driven between the impeller and the motor by a coupling. No. 2.8 ~ 5 adopts Type A transmission, and type A, C and D transmission adopts
TED is No. 6, and No. 8-12 uses type C and D drives.
F4-72 fan is a derivative series of 4-72 fan, is a corrosion resistant fan. It's made of fiberglass,
And all metal parts are covered with anti-corrosion coating, which can effectively prevent all parts of the fan from being corroded.
B4-72 fan is also a derivative series of 4-72 fan, which is a special fan for explosion-proof occasions. explosion-proof
The motor and key components are covered with anti-static surfaces or non-ferrous metal materials, which can effectively prevent friction
Electrostatic discharge and spark leakage of electrical components.
The f4-72 fan has the same performance, selected parts and base size as the 4-72 fan. Performance, sele
The CTED parts and basic dimensions of the B4-72 fan are the same as those of the 4-72 fan, and the structure is basically the same. Type B35
No. 2.8 ~ 6a uses motors with flanges and feet, and No. 6 ~ 12C and No. D uses Yb series 3 motors corresponding to the Y series.
