Why Do You Need a Bathroom Exhaust Fan?
There are 3 main reasons as to use exhaust fans:
- To remove impurities in the air, eg: moisture, smells, heat etc.
- To encourage air circulation in bathroom or closed space.
- To transfer tempered (warm/cool) air from one place to another.
Exhaust Fans also help keep your bathroom clean and healthy by helping eliminate condensation and mould.
1. Ceiling Exhaust Fans
How it works
Ceiling Exhaust Fans expel air upwards through the ceiling and can be exhausted into the roof cavity or ducted to be exhausted outside.
Determine the airflow requirements
The fan’s extraction rate should match the room size to achieve the recommended number of air changes. This is easy to work out with your rooms measurements and our Exhaust Calculator.
If the fan is undersized, it won’t ventilate effectively; if oversized, it can waste energy and sometimes be noisier.

Replacement exhaust fans
The old unit will need to be removed. Measure the existing cutout to ensure the new fan fits.
New installations
Cut a hole in the plasterboard as required by the chosen model. An electrician may be required to install an electrical switch into the roof cavity if one is not available.
Do you want to duct the fan?
Modern homes typically duct the air outside. We recommend that the duct run is as short and direct as possible to improve your fans performance.
If your home has a well-ventilated roof space, you can vent into the cavity.
Warm steam can trigger condensation and drip from the exhaust fan fascia.
There are also safety risks if IP rated fans are not installed.
If above the shower is the only installation option, we recommend installing an inline fan or roof mounted fan.

2. Wall Exhaust Fans
When to use a wall exhaust fan
Wall exhaust fans are great solutions for when space in the roof is limited.
How it works
Most wall exhaust fans have an internal motor connected to an external vent via ducting or tubing.

Fan featured is the 150 Quiet 2 Speed Fan
What to do when buying a replacement exhaust fan
Remove the old fan and measure both the wall hole and wall depth before purchasing a replacement.
New installations
Ensure the unit suits your wall depth. Most exhaust fans come with a template to help you accurately mark the hole size required.
Fan Styles and Capacity
Choose between models with the motor inside the room or mounted externally. Options range from standard toilet fans to high-capacity units for larger spaces.

3. Inline Exhaust Fans
How an inline exhaust fan works
Inline fans are installed within the ceiling cavity, mounted between duct lengths. They’re ideal for areas that do not have clearance or roof space for a ceiling exhaust fan.
Inline fans are often quieter than ceiling exhaust fans or wall fans.

4. Window Exhaust Fans
Window exhaust fans applications
Window exhaust fans are ideal for apartments and units with limited roof space.
How they work
A window fan consists of two parts that fit together through a hole in the glass, creating a weatherproof seal while exhausting air directly outdoors.
Key consideration – hole size
The most important factor when purchasing a window fan is the hole diameter. When replacing an existing unit, remove it first to measure the hole accurately. For new installations, a glazier is required to cut the hole in the glass.
