Frequently asked questions about the Ventilation category
Ventilation — what is it and why is ventilation needed in a house?
Ventilation — is a system for exchanging indoor air, supplying fresh air and removing moisture, odours and harmful gases. In a private house this includes supply and extract fans, recuperators and PVC/duct fittings to maintain comfortable indoor air quality and prevent mould.
What ventilation is suitable for a private house — supply, extract or recuperator?
A combined supply-and-extract system with a heat recuperator is ideal. Units like the E-EXTRA EER125WP recover heat, while PVC or metal ducts and grilles distribute air to rooms efficiently.
How to choose ventilation for a bathroom?
Choose an extract fan D100–D125 mm with a timer or humidity sensor (e.g. E-EXTRA EAT125HT). Fit a D100/D125 grille and a flexible or rigid PVC duct to route moist air to the ventilation shaft.
What ventilation is needed in an apartment — is an extract fan enough?
Often an extract fan in the kitchen and bathroom (D100–D125 mm) plus supply valves and grilles is sufficient. In airtight flats, a supply-and-extract system or recuperator is recommended to ensure good air quality.
How to ventilate a cellar — which pipes and grilles to choose?
Use a basic supply-and-extract layout with rigid PVC ducts or flexible D100–D125 mm ducting and corrosion-resistant grilles. Place intake and exhaust at different heights to remove moisture effectively.
What ventilation is needed for a garage — fan or duct system?
A garage typically needs an extract or supply-and-extract fan with duct sizes D100–D160 depending on volume. Use metal or plastic grilles and add a silencer if noise reduction is required.
How to provide ventilation in a basement and cellar — are filters needed?
Use continuous airflow via D125–D160 ducts and grilles; if odour or dust is present, add mechanical filtration (G4). Filters like F100/F125-G4 remove coarse particles and help prevent mould.
What are ventilation grilles and how to choose the right one?
Grilles cover duct openings and come in plastic or metal (sizes like 140x190, 140x105, D100). Choose plastic for wet rooms and metal for visible or external locations based on durability and design.
Which ducts and fittings are used — is flexible or rigid duct better?
It depends on the route: flexible aluminium or plastic duct (e.g. GC100-1.5-FF D100x1.5m) is convenient for bends; rigid PVC and rectangular ducts (220x90 mm) give lower airflow losses and connect well to flanges and elbows.
How to install a supply valve and what sizes are available?
Install supply valves in an external wall or window frame, selecting D100–D160 based on airflow requirements. The range includes metal valves and noise-insulated models (SMK3-100DB) for quieter operation and adjustable supply.
Which fans are suitable for the kitchen — axial or duct fan?
Use duct fans and extract hoods with D100–D160 connections for kitchens to connect to ducts and exhaust. E-EXTRA models (e.g. EAT100) are designed for duct connections and provide suitable airflow.
