mining are driven by electric motors, although internal combustion engines may be employed, particularly as a standby on surface fans. Compressed air or water turbines may be used to drive small fans in abnormally gassy or hot conditions, or where an electrical power supply is unavailable. In Chapter 4, mine fans were classified in terms of their location, main fans handling all of the air ...

The use of "booster fans" sited underground and acting in series with the surface fan will become more common. While such strategies may be preferred they raise difficulties in relation to interlocking surface and underground fans, avoiding recirculation and separately ventilating underground fan motors to ensure gas-laden air does not pass over the motor(s).

AC-powered fans usually use mains voltage, while DC-powered fans use low voltage, typically 24V, 12V, or 5 V. Cooling fans for computer equipment always use brushless DC motors, which generate much less electromagnetic interference than other types.
What is a blower resistor? Blower resistors are resistors which are used to control the fan speed of automotive blowers. The fan speed can be changed either by switching the blower resistor resistance mechanically, using a rotating lever, or electronically by the air conditioning system.
