Answer» Exhaust fans work by sucking hot or humid air out of a small, localised area, allowing fresh air to enter from elsewhere (perhaps a doorway or vent) in order to replace it. The warm air that's drawn out using an exhaust fan is then pulled through a ducting system and expelled outside. How effective are exhaust fans: As these fans are only really effective in smaller rooms, one that is capable of moving approximately 2 cubic metres per second usually provides sufficient ventilation. For larger areas, a larger ventilation system may be more appropriate. Installation of exhaust fan: 1. Drill a reference hole and mark the ceiling. 2. Cut the intake-port hole. 3. Put the fan in position 4. Secure the fan to the joists 5. Find a suitable exit point for the duct pipe 6. Attach the vent cap 7. Wire the connections in the housing unit. 8. Attach the grille |
