Forced air cooling should be used only when natural cooling is not adequate.
Exhaust and recirculating fans and blowers should be driven by ac brushless motors or by properly shielded dc motors.

Fan Notes

CFM stands for Cubic Feet per Minute.
Fans are divided into either AC or DC type fans;

Brushless DC fans are available at three nominal voltages: 12V, 24V and 48V. The speed and airflow of a typical DC fan is proportional to the voltage supplied. The life expectancy of a DC fan is higher than that of a comparable AC fan, independent of the type of bearing system employed, since DC fans are up to five times as efficient. How ever DC fans have much higher starting torque than AC fans.
Both ball bearings and sintered sleeve bearings are employed in fans, each sufficiently lubricated for the intended service life. In general, ball bearings provide a higher life expectancy than normal sleeve bearings. Fans configurations are listed below:

Axial fans are used where high air flow under low pressure is needed. Sub-classification according to impeller type;
.....Propeller fans: Most economical and least efficient
.....Tubeaxial fans: Consists of an impeller rotating within a cylindrical housing, more efficient than a Propeller alone
.....Vaneaxial fans: A Tubeaxial fan with guide vanes making it more efficient
.....Multi-Stage axial blowers: Two or more Vaneaxial fans mounted on a common shaft

Radial fans produce lower air flow than axial types, but under higher pressure.

An AC induction capacitance fan uses a capacitor which is connected to an auxiliary winding to assist in starting the fan. The capacitor is added to the circuit via induction, but both the inductor and capacitor are removed from the circuit by a centrifugal switch [once the fan gets moving].

Fan Speed Laws; CFM varies directly with rpm. Static Pressure varies as the square of rpm. Horsepower varies as the cube of rpm.

Fans may have a number of leads, including; Power, Ground, Tach or PWM. The Tach or tachometer signal measures the speed of the fan.
The Pulse Width Modulation lead is used to change the speed of the fan. Also refer to an example Fan Pin-out on an ATX Mother-board.

Suction type fans are fans that draw air into an enclosure. Exhaust type fans force air out of an enclosure.
