Ventilation
Detailed ventilation category for renovation, bathroom extraction, kitchen extraction, decentralised ventilation, ducting, grilles, humidity control, air transfer, indoor air quality, mould-risk reduction, technical installation and renovation compliance support.
Ventilation is not only comfort
Ventilation protects the building and the occupants. Poor ventilation increases humidity, condensation, odours, mould risk and damage to finishes. In renovation work, ventilation must be planned together with insulation, airtightness, heating, windows, bathrooms and kitchen extraction.
Main Product Families
A renovation ventilation setup can be simple or advanced. The correct choice depends on room type, moisture load, duct route, noise, controls, airflow, wall openings and whether heat recovery is needed.
Bathroom Extract Fans
Fans for showers, bathrooms, toilets, humid rooms and small wet-zone ventilation.
- Timer and humidity models
- Wall or ceiling installation
- Backdraft shutter options
Kitchen Extraction
Extraction solutions for cooking vapour, odours, grease, moisture and air quality.
- Cooker hood extraction
- Recirculation and filters
- Duct and wall outlet planning
VMC Units & Humidity Extraction
Central and compact mechanical ventilation units for humidity extraction in bathrooms, toilets, kitchens, laundry rooms and apartments.
- Single-flow VMC units
- Humidity-controlled extraction
- Wet-room and apartment ventilation
- Air inlets, ducts and grille coordination
Decentralised Ventilation Units
Single-room ventilation units, including heat-recovery options for renovation projects.
- Wall-mounted units
- Heat recovery options
- Useful where central ducts are difficult
Inline Duct Fans
Fans installed in duct routes for bathrooms, toilets, utility rooms and technical extraction.
- Inline fan installation
- Higher duct support
- Remote fan placement for noise control
Ducting, Grilles and Air Valves
Ducts, bends, reducers, grilles, air valves, wall outlets and transfer openings.
- Round and flat ducts
- Supply/extract grilles
- Wall and roof terminals
Humidity, CO₂ and Control Sensors
Controls for automatic ventilation based on humidity, CO₂, occupancy, timer or manual switching.
- Humidity sensors
- CO₂ monitoring
- Timer and boost controls
Bathroom Extract Fans
Bathroom extraction is one of the most important renovation ventilation tasks. The fan must remove humid air quickly enough, without excessive noise or backdraft.
Standard Bathroom Fan
Simple extract fan for bathrooms, toilets and small humid rooms.
- Wall or ceiling mounting
- Simple switch operation
- Good budget option
Bathroom Fan with Timer
Continues running after light switch-off to remove remaining humidity.
- Run-on timer
- Better moisture removal
- Useful for small bathrooms
Humidity-Controlled Fan
Automatically boosts when humidity rises after showering or bathing.
- Automatic humidity response
- Better mould-risk control
- Useful for rental and renovation projects
Kitchen Extraction
Kitchen ventilation must handle odours, cooking vapour, humidity and grease. Extraction to outside is usually more effective than recirculation, but ducting and building constraints matter.
Cooker Hood Extraction
Extraction systems connected to an exterior outlet through ductwork.
- Better odour removal
- Requires duct route
- Check backdraft protection
Recirculation Hood Filters
Carbon and grease filters for recirculation systems where external exhaust is difficult.
- Grease filter maintenance
- Carbon filter replacement
- Does not remove moisture like exhaust
Kitchen Ducting and Wall Outlet
Duct components and exterior outlets for kitchen extraction routes.
- Short route preferred
- Reduce sharp bends
- External grille or wall terminal
Decentralised Ventilation Units
Decentralised ventilation is useful in renovation where central ducting is difficult. Single-room units can ventilate bedrooms, living rooms, studios, offices, basements and renovated rooms.
Single-Room Wall Ventilator
Wall-mounted ventilation unit for direct outside air exchange.
- Useful without central duct system
- Wall core drilling required
- Room-by-room solution
Decentralised Heat-Recovery Unit
Single-room ventilation with heat recovery to reduce heat loss.
- Heat recovery core
- Better energy performance
- Good for insulated renovations
Push-Pull Pair Ventilation
Two alternating units used as a balanced room ventilation strategy.
- Alternating air direction
- Balanced room concept
- Useful for bedrooms/living rooms
Inline Duct Fans
Inline fans are installed inside duct routes instead of directly on the wall or ceiling. They can move more air and can be placed away from the room to reduce perceived noise.
Standard Inline Duct Fan
Fan installed in round ducting for bathroom, toilet, utility or technical room extraction.
- Round duct connection
- Useful for longer duct runs
- Remote fan placement possible
Low-Noise Inline Fan
Designed for lower noise extraction in apartments, bathrooms and sensitive rooms.
- Lower sound level
- Flexible mounting
- Good for residential renovation
Boost Extraction Fan
Higher airflow fan for utility rooms, larger bathrooms or longer duct routes.
- Higher airflow
- Longer duct support
- Check noise and pressure
Ducting, Grilles and Air Valves
Good ventilation depends as much on ducting as on the fan. Bad duct routing, crushed flexible ducts, too many bends or small grilles can ruin performance.
Round and Flat Ducting
Duct components for routing air through walls, ceilings, cabinets and technical voids.
- Round ducts
- Flat ducts
- Reducers and bends
Extract and Supply Grilles
Visible air terminals for extraction, supply or transfer airflow.
- Wall grilles
- Ceiling valves
- Adjustable air valves
Wall, Roof and Exterior Terminals
External ventilation outlets with weather protection and backdraft control.
- Exterior wall outlet
- Roof terminal
- Backdraft shutter
Humidity, CO₂ and Control Sensors
Controlled ventilation is more practical than manual ventilation only. Sensors help ventilation react to real conditions: humidity, CO₂, occupancy or time schedule.
Humidity Sensor Control
Automatically activates or boosts extraction when humidity rises.
- Bathroom and laundry rooms
- Moisture control
- Useful after showers
CO₂ Air Quality Monitor
Monitors indoor air quality and indicates when ventilation is insufficient.
- Bedrooms and living rooms
- Office and study rooms
- Ventilation performance feedback
Timer, Boost and Manual Controls
Switches, timers, boost buttons and smart controls for practical ventilation operation.
- Run-on timers
- Boost switch
- Manual override
