Types of mechanical ventilation

The main element of mechanical ventilation is the installation or several installations ensuring the exchange of air in the premises.

Both centralised and decentralised mechanical ventilation solutions are available.

Decentralised ventilation systems

In the case of a decentralised ventilation system, separate installations ensure air exchange in individual rooms or groups of rooms.
There are solutions, where air supply and air exhaust are ensured by separate installations or simple fans.
Such solutions are suitable for multi-apartment buildings, where all the dwellers of the building do not want or cannot install a joint ventilation unit.

Centralised ventilation systems are intended for both private houses and multi-apartment houses.
In this case, one installation takes care of air exchange with the air circulation through separate air channels.
It is recommended to install fresh air supply channels in the rooms where fresh air is needed primarily, such as the bedroom and the living room.
It is recommended to install air exhaust channels in the kitchen, bathroom and toilet.
It is not desirable to install fresh air supply channels and indoor air exhaust channels located on the outside of the building close to one another so that the ventilation unit does not suck back into the building the air that has just been extracted from the housing.
