What do I need to know about my home’s ventilation system?

The ventilation system renews the air within the dwelling, removes pollutants and excess moisture, and provides oxygen to combustion machines.

The air we breathe is charged with steam that can condensate on cold walls. Excess moisture may damage your home such as mold apparition or loosening of the wallpaper, and cause you health problems such as asthma or respiratory allergies.

If the ventilation system is properly installed and well maintained, the energy expenses can be well controlled. For a better ventilation system, you can choose a Controlled Mechanical Ventilation (CMV) system.

The air extractor

An air extractor removes polluted air and moisture from inside the dwelling and is the most basic ventilation system. They use to be installed on walls or to the roof in humid rooms such as toilets, laundry, bathroom or attic.

An air extractor is composed with a motor and a fan to remove the polluted air. The motor is usually installed in roofspaces or attics and is connected to the house by a ductwork. The polluted air is carried through ducts and is exhausted through extract units. The air or insufflating intakes allow the air to be renewed on a regular basis or according to the moisture rate.

They are various extractor models: The single-flow model that permits the air into the dwelling thanks to the self-adjusting air intakes located over the windows, and the hygro-adjusting model that is adjusted according to the moisture rate.

You can easily install the air extractor by yourself. They use to be delivered in kit and for a better comfort, it is recommended to install a silent air extractor.

You can find our air extractor models on our website.

Self-adjusting ventilation system

The self-adjusting ventilation system allows you to renew the air inside the dwelling while keeping your room temperature the same. Such system is the most used in France

This ventilation system is installed in humid places such as the kitchen, the bathroom, the toilets or the cellar. The exterior air comes inside the dwelling through aeration grids and is then exhausted through aeration ducts controlled by a reverted fan that is powered by an electric motor that use is usually installed in roofspace or laundry.

The new air comes above the windows through auto-adjustable air intakes. In more humid rooms, the polluted air is exhausted by vents that are connected to a ventilation group. Such model saves you time and costs in installation but does not consider the outside conditions such as wind or rain, nor inside conditions such as room moisture.

You can find on our website our self-adjusting air intakes models. as well as our self-adjusting extract units.

Hygro-adjusting ventilation system

The hygro-adjusting system adjusts a house ventilation system according to the moisture rate in the room. The air can be renewed while the room temperature remains the same.

Thus, when you leave your house, the ventilation system slows down.

The polluted air is exhausted from humid rooms such as kitchen, bathroom or cellar by hygro-adjusting vents which open and close according to the room moisture. These vents are connected to the CMV by isolated ducts.

There are two models of hygro-adjusting CMV: single or double flow model. The single flow model works like a classic CMV but is connected to a hygro-adjusting housing that permits the air flow, also called the lifting speed to change.

Save up to 15% on your heating bill thanks to the hygro-adjusting ventilation system.

How do I maintain my CMV system?

A ventilation system must be properly maintained to work well. If you are equipped with a Controlled Mechanical Ventilation system (or CMV), be careful with dust. Accumulated dust impedes ventilation but can also prematurely deteriorate the system. A bad maintenance means bad ventilation and can cause condensation problems and molding.

If you are equipped with a single flow ventilation system, you are recommended to clean the aeration vents and air inlets on a quarterly basis. Dismantle them with caution and use a humid wipe with soap. Rinse them then replace them on their support

The ventilation housing must be cleaned once a year.

If you are equipped with a double flow ventilation system, you must clean the insufflations and extraction filters once a year. The stationary parts of hygro-adjusting air intakes must NOT be in contact with water!

The complete maintenance of the ventilation system must be done by an expert every 3 years.
