Mechanical Ventilation by Insufflation

About

Comprehensive damp treatment particularly suited to Brittany
For existing single-storey and multi-storey homes up to 250m². Helps reduce humidity in the home via an air injection point, subject to appropriate sizing and sufficient air inlets and outlets. This system can help reduce certain humidity-related issues, such as condensation and mould, depending on the condition of the home, its existing ventilation and its use. Insufflation ventilation can help reduce radon concentrations in certain buildings. Its effectiveness must be verified by appropriate measurements before and after the work.
A 100% self-contained system, it automatically adjusts its operating flow rates according to the seasons. It also regulates temperatures to optimise comfort. It limits rising damp and improves occupants’ breathing comfort and sleep quality thanks to the action of positive pressure. It requires openings to the outside in damp rooms, such as bathrooms and toilets, and vents on kitchen windows.

Suitable for renovation
A solution suitable for renovation projects where installing a conventional extract-type CMV system proves difficult or even impossible.
The centralised system (preferably in the loft) uses a single entry point into the house via a diffuser, which then distributes air to all rooms. The air is distributed in this way, using the house’s air leaks as outlets.

Filtration and heating of incoming air
Contributes to the renewal and filtration of incoming air. The effects on thermal comfort and energy consumption depend on the building, the installation and usage patterns. The filter is oversized to allow for infrequent maintenance (once every 5 years) whilst ensuring effective air filtration. Its positioning in the loft and the preheating coil ensure that the supply air temperature is always above 10°C. This prevents draughts around window ventilation grilles and limits the transmission of external noise.

Particularly suitable for wood and pellet heating
May help to limit certain backdraft phenomena, without replacing the need for appliance maintenance, draught checks, proper ventilation and suitable safety devices. This does not eliminate the risk of carbon monoxide poisoning. Promotes the thermal draught of installations and facilitates the ignition of solid fuel appliances, such as wood and pellet stoves.
