In renovation, it is not always possible to install a VMC. Another effective system can be implemented: the VMR (regulated mechanical ventilation).

Diagram of a VMR

Regulated mechanical ventilation (VMR) prevents the passage of ducts throughout the house. It therefore offers great ease of installation and satisfactory results.

VMR (regulated mechanical ventilation): mechanical ventilation

The VMR consists of air extractors installed in damp rooms. They are similar to VMI aerators except that they operate continuously and at a user-defined speed. They are less powerful and therefore less noisy.
The air circulates in all rooms: it penetrates through the vents on the windows and flows into the wet rooms from which it is extracted.
