Installation Locations
It is not recommended that Exhaust Vents be installed in ceiling
above 2.4m, as it can limit the effectiveness of the extraction of
moisture and steam.
Specification
Please read before beginning installation:
The manufacturers warranty will not be covered if the product is installed in a room with systems or structures which do not

Sizing Your Ventilation System
Step 1
Select your required application:
-
Bathroom (15 minimum air changes per hour)
-
Toilet (10 minimum air changes per hour)
“Air Changes per Hour” means an airflow rate sufficient enough to remove/replace the total volume of air in a given room at a
specified number of times per hour

Step 2
Calculate room volume:
To calculate the volume of the room in cubic meters (m
3
) _ multiply the length x width x height. Eg:
2.2m x 2.5m x 2.4m = 13.2m

Step 3
Calculate fan performance requirement:
To calculate the exhaust fan performance requirements multiply the room volume by the
maximum recommended air changes (bathroom = 15).
Eg: 13.2m3 x 15 = 198m3/hr
Step 4
Determine ventilation requirements:
Using the provided Performance Curve Chart identify your exhaust vent performance
requirements.
