How to adjust the blade angle of an air-cooled fan
Thread Content
As the temperature rises, the temperature of the air-cooled fan doesn’t drop; I want to increase the angle of the fan blades, but I’m not sure what tool to use for measuring and making the adjustment.
To adjust the angle of the blades of an air-cooled fan, an angle gauge is required. A reference point is marked on the blade, and by using the angle gauge, the blade angle can be adjusted. After making the adjustment, it is important to monitor the motor’s operating current to ensure that it does not operate above its rated current.
Ask the after-sales staff of the manufacturer to adjust the angle.
There are specialized tools available, or it’s simple to create one yourself – it’s just an angle gauge, and the principle behind it is very simple
Adjust it using an angle gauge; however, the blade angle of cooling tower fans generally should not exceed 13 degrees
