Product catalogue «Domestic fans»

Domestic fans are intended to ensure forced mechanical supply and extraction of air in houses and flats.

The fans are installed directly into ventilation shaft openings or integrated into systems of air ducts and ventilation ducts.

As a rule, domestic fans are installed in spaces with the highest air contamination and moisture levels such as toilets, bathrooms and kitchens.

The fan air capacity is calculated based on the space volume and minimum air exchange rate. 

The amount of ventilation air is calculated for each space individually in consideration of the presence of hazardous agents (substances) or specified according to the preliminary assessment results. If the nature and amount of hazardous agents (substances) cannot be quantified, the air change is expressed in air change rate:

L = Vspace * Ach (m3/h),

where Vspace is the space volume [m3];
Ach is the minimum air change rate [1/h],  see the air change rate table.

How do you calculate the space volume?

To calculate the total space volume in cubic metres.
Use this simple formula:

Length х width x height = space volume [m3]
A x B x H = V (m3)

For example, the room is 7 m long, 4 m wide and 2.8 high. To define the volume of ventilation air calculate the room volume: 7 х 4 х 2.8 = 78.4 m3. Then use the tables below with recommended air change rate to define the required fan capacity.
