1. Direction of rotation is determined from drive side of fan.
2. On single inlet fans, drive side is always considered as the side opposite fan inlet.
3. On double inlet fans with drives on both sides, drive side is that with the higher powered drive unit.
4. Direction of discharge is determined in accordance with diagrams. Angle of discharge is referred to
the vertical axis of fan and designated in degrees from such standard reference axis. Angle of discharge may be any intermediate angle as required.
5. For fan inverted for ceiling suspension,or side wall mounting, direction of rotation and discharge is
determined when fan is resting of floor.
Note : The centre of the fan or suction opening of the measuring duct
should position 1 D or more apart from wall or floor.
D : the diameter of the fan suction opening or measuring duct.
