Insufflation ventilation

Insufflation ventilation, also known as VMI (Mechanical Inverse Ventilation), is the ideal alternative to single-flow mechanical ventilation for ventilating a renovated home. This reverse mechanical ventilation system is the solution to address condensation and humidity issues in a dwelling.

How does the VMI system work?

The positive pressure ventilation system operates in the opposite way to a “conventional” ventilation system. This means that the air is filtered, preheated, and then blown into the dwelling, creating a slight positive pressure. This process eliminates the effects of condensation and helps to eliminate mold and moisture stains.

The filtration system prevents contamination from the outdoor air and purifies it before it enters the dwelling. As a result, pollen, allergens, and other pollutants are filtered out, thereby improving the indoor air quality of the dwelling.

What is the difference between a VMC and a VIM?

The principle of operation for a VMC is to extract stale air from humid rooms and supply fresh air to living areas. In contrast, a VIM functions by blowing filtered fresh air from the outside directly into the humid rooms, creating a slight positive pressure in the dwelling. This process facilitates the removal of condensation and humidity, thus improving air circulation and renewal.

Why choose to install a VMI (Mechanical Inverse Ventilation)?

The VIM (Positive Pressure Ventilation System) is a ventilation system that offers numerous advantages. Insufflation ventilation is recommended for individuals suffering from asthma or allergies, as well as for homes experiencing humidity issues.

This type of installation is particularly suitable for renovated homes. VIM is compatible with fuel-based heating systems, as well as other external heating sources such as Canadian wells and solar panels.
