Why Use An Exhaust Fan?

There are 3 main reasons as to use exhaust fans:

  1. To remove impurities in the air (moisture, smells, smoke, heat etc)
  2. To encourage air circulation within an area
  3. To transfer tempered (warm/cool) air from one place to another

These factors play a part in determining which exhaust fan will be suitable for the desired application. It can also be used to help eliminate condensation and mould in moisture exposed spaces.

This is a general guide to the majority of exhaust fans. If you have any questions regarding your own exhaust solution, please feel free to email us.

The steps required in picking out the correct exhaust fan are:

  • Determine what variant of exhaust is required and how it will be mounted (eg wall, ceiling, window etc)
  • calculate the area being exhausted (Length x Width x Height). This will give you a figure in m3 (cubic meters)
  • multiply this with the number of air-changes required (8 for a subfloor/meeting area, 13-15 for a bathroom or toilet , 15+ for smoke exhaust). If you like to have long, hot showers or are concerned about steaming up the bathroom then please use a figure of 20 – 30 air changes per hour
  • determine whether to duct directly into the roof space, duct out through the roof or through a wall/eve
