What is principle of operation of exhaust fan? Explain the installation of exhaust fan in details.

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
