Ceiling Exhaust Fans
Guide To Ceiling Mount Exhaust Fans
Ceiling mounted exhaust fans are the most popular choice for domestic bathroom / toilet ventilation in Australia. At Fansonline we have a large range of ceiling mounted ventilation fans, including ductable and non-ductable models. There are a few basic rules to picking a domestic ceiling mounted fan:
- Is the fan a new installation or are you replacing an old fan? If you are replacing an old fan you will need to completely remove the old fan and measure the hole size. For a new installation the hole size is less of an issue, as you will need to cut a hole in the plasterboard regardless.
- Do you wish to duct the fan? The majority of ceiling exhaust fans are now being ducted outside, however if you have a well ventilated roof space you may wish to vent into the cavity. If you are ducting the fan its best to keep the duct run as short and direct as possible.

How do I calculate which exhaust fan I need?
Fan suitability is usually determined by your room size and application. Generally we recommend aiming to achieve 15 air changes per hour for a bathroom, maybe 10 for a toilet. This is easily calculated, simply work out the size of your room in m3 (length x width x height in meters). You can then multiply this figure by 15 to give you an approximate capacity rating required for the fan. For your convenience all fans are measured in m3/hr. Please note 15 is our general recommendation, rooms prone to condensation may require 20-30 air changes.
