What we do

Our ventilation services

Main service

System C: mechanical extraction

With System C, a central fan extracts the humid air from your wet rooms. Fresh air enters via grilles, so there's no need for supply ducts to run through your home. That makes it easy to fit during a renovation. Sensors for humidity or CO₂ ramp the system up automatically.

Extraction in the kitchen, bathroom and toilet
Fresh air via grilles; no supply ducts required
Humidity or CO₂ control ramps up by itself
Easy to incorporate into a renovation project

System D: balanced ventilation with heat recovery

System D extracts air and blows in fresh air at the same time, via a central unit that recovers up to around 90 per cent of the heat from the outgoing air. It does require a complete network of ducts, so it's mainly a choice for new-builds or major renovations.

Both supply and extraction are mechanical
Heat recovery of around 90 per cent
Filters block dust and pollen
Mainly for new-builds or major renovations

What Ahmed does with your ventilation system

Ahmed mounts the unit, connects it to your electrical installation, lays the wiring for the sensors and controls, and balances the airflow room by room. He runs the ducting as short and tidy as possible and finishes the grilles off neatly. A properly set-up system runs quietly.

Mandatory when renovating, and grants

In Flanders, you're required to install a full ventilation system in new-build properties and for major energy renovations. For a home over ten years old, installation by a contractor usually qualifies for the reduced 6 per cent VAT rate. For the latest grants, it's best to check the official grant simulator.
