Evaporator fan blade or blower It is the driving force for the movement of the wind. by getting power from an electric motor Small particles of dust emanating from the trapping of some of the air filters. It will catch on the fan blade, causing the fan blade’s wind lap groove to be clogged, unable to fully scoop the wind.

The occurrence in this manner will cause the amount of cold air. that goes out of the evaporator drop Therefore, it takes longer to run the air conditioner. in order to get the same room temperature which resulted in an increase in the cost of electricity In addition to the dust that sticks on the fan blades, it will cause the fan to send less cool air. may cause
Loud noise that the evaporator unit can rise Because the dust that is caught will add weight to the propeller. causing the propeller to lose its own balance And when the motor rotates, it will vibrate from the centrifugal force and cause noise.
