WebVariable pitch fan operators used in air coolers can be described in general terms as very similar to diaphragm operated, spring return valves. Instead of moving a valve stem up and down the operator controls fan blade pitch. A force diagram is shown in Fig. 4. As the blade moves the air, the aerodynamic moment (CW) tries to feather the blade ... Web7 feb. 2024 · The minimum distance between the ceiling and fan blades should be 8 inches. This distance provides sufficient space for air to move above the fan blades and get pushed down. What is mentioned above is the minimum distance. Any distance above this will not adversely affect the airflow of the fan.

The motor is likely an induction type, which by design, "slips." So the more load placed on it, the slower it will spin. Which means, if you increase the blade pitch angle, this will produce more load for the motor, resulting in lower RPM, and probably a very similar amount of airflow overall.
