What is a Fan ?

- Any device that produces a current of air by the movement of broad surfaces can be called a fan.
- Fans fall under the general classification of Fans fall under the general classification of “turbomachinery” and have a rotating impeller at least partially encased in a stationary housing.
- Fans are similar in many respects to pumps. Both are turbomachines that transfer energy to a flowing fluid. It is easy to distinguish between fans and pumps: pumps handle liquids; fans handle gasses.
- Broadly speaking, the function of a fan is to propel, displace, or move air or gas.

       
  Orientation of Fan and Motor
       
  industrial fan motor positions
  The drawing above illustrates the Amca motor position standards for arrangement 1 and 3 fans (arrangement 1 shown). The location of the blower motor is determined by facing the drive side of the fan and designating the motor position by letters w,x,y, or z, in accordance with the diagram show above.
  industrial fan blower rotation and discharge
  Direction of rotation is determined from drive side of the fan.
on single inlet fans, the drive side is always considered the side opposite the fan inlet.
the direction of discharge is determined in accordance with the diagrams shown above. the angle of discharge references the vertical axis of the fan and is designated in degrees above or below that reference axis.
on fans inverted for ceiling suspension or side-wall mounging, the discharge is determined when the fan is testing on the floor.
