Forced ventilation in the bathroom and toilet

All bathrooms in apartments and private houses are characterized by high humidity with constant temperature changes. If ventilation in the bathroom and toilet is calculated or done incorrectly, mold will appear in them. And often natural air exchange for these rooms is not enough. Then it is necessary to install a forced ventilation system with various fans. Otherwise, without additional ventilation, the walls in such rooms risk quickly turning into a fungal farm.

Main types of ventilation

Ventilation in the bathroom can be:

• natural;
• forced.

The first works due to the usual air convection. Heated air masses naturally always rise to the ceiling of the bathroom. Moreover, if there is a ventilation hole with an advertising data into the ventilation duct in the upper part of the bathroom or toilet, then the air goes further up. And instead of its lost volumes, new ones are drawn in through the door, which creates a natural draft in the room. As a result, a constant air exchange occurs.

Ventilation and ventilation system equipment

Conventional ventilation in the bathroom and toilet includes a ventilation duct to the common shaft (riser) and a grate on the wall. Plus, in addition to this, filters are often installed in the air duct. But if the ventilation system is made forced, then it must have a fan. And a control unit and other automation are added to this equipment.

If exhaust or supply ventilation is selected for installation, one in addition to the seo module capabilities duct will be enough. However, for a combined supply and exhaust option, two separate air ducts are required between the bathroom and the street. One will supply air, and the other will exhaust it.

Bathroom Ventilation Installation Tips

Installation of forced ventilation in the bathroom and toilet of the apartment is most often done in the exhaust version. To do this, a small axial fan of the required power is placed in the existing ventilation duct and fixed there. The air ducts already exist, it is impossible to expand or completely replace them with new ones. If necessary, all that remains is to install an exhaust fan in them.

Hello, dear friends. Today we will talk about very important, though sometimes not obvious, things. When planning the design or renovation of bathrooms, you should always consider the ventilation system. The problem of air exchange is a serious and very important stage of renovation. In SNiPs and italy numbers regarding ventilation, the standard of air exchange rates in rooms with abundant water vapor emission is always spelled out in separate points.

What should a good ventilation system in a bathroom be like?

Construction reference books of all countries and peoples contain a number of standards that must be strictly followed in order to ventilate damp rooms.

Ventilation systems must enrich the bathroom with 25 cubic meters of air every hour. For a combined bathroom (bathroom + toilet), ventilation must bring 50 cubic meters of air. Moreover, these standards are minimal.

Ventilation system specialists recommend ventilating bathrooms with an air exchange rate of 75 cubic meters per hour and 150 cubic meters for combined bathrooms.
