How to determine the direction of centrifugal fan?
When the impeller is counterclockwise rotation and the fan outlet in the lower right to obliquely above 45 degrees blowing gas called the left 45 degrees
When the impeller is clockwise and the fan outlet is in the left to the vertical 90 degrees above the vertical blown gas called the right 90 degrees when the impeller is counterclockwise rotation and the fan outlet in the lower right to the horizontal direction when the gas is called left 0 degrees
When the impeller is clockwise rotation and fan outlet in the lower left to oblique above 45 degrees blowing gas, said the right 45 degrees
When the impeller is clockwise rotation and the fan outlet in the lower left to the horizontal direction when the gas is called the right 0 degrees
Determine the direction of the centrifugal fan first in accordance with the location of the station is located on the other side of the fan inlet is the bearing side to watch the fan when the impeller is clockwise rotation called the right-hand wheel is counterclockwise rotation called the left
