Can high pressure fan inlet and outlet be reduced?
It can be reduced and reduced, but be careful not to become too small, usually not less than one-half of the cross-sectional area of the fan itself.
Because the inlet and outlet of the high-pressure fan itself is fixed, it is necessary to use reducing pipe fittings to change its caliber size.
After the inlet or outlet of the fan is changed, the pressure will increase a lot, and the flow rate will increase. Usually, it is used more in hot air drying.
You can also use a tee or a tee, and it is also possible to divide a few more thin tubes, but the cross-sectional area needs to be calculated, and it should not be too small, causing the motor load.
In addition, the fan is not allowed to block the inlet or outlet operation for a long time, otherwise the wind machine will be very hot, and the worst degree is to burn the machine, which can be operated in a short time.
