An exhaust can be useful in a bathroom or laundry, or any
room where there might be excess steam and moisture in the air. This will
prevent mould and mildew from building up in the room and potentially damaging
your home.
The first thing to figure out is how strong you need the
exhaust fan to be in order to extract all the moisture in the air is to measure
your room. You will need to measure the length, width and height of your room
and then multiply those numbers together (L X W X H). Then you want to take this
number and times it by 15, which is the average number of air changes needed
per hour. For example an average sized bathroom which is 2m X 3m X 2.7m =
16.2m3 X 15 = 243. This simply means you want an exhaust fan with a minimum
airflow of 243m3 per hour. Anything with a higher airflow will be even better
in your room. This is just a very rough calculation, talk to your electrician
or call us for more information.
