How It Works
Developed in Finland, tested in Nordic conditions
The Mobair ventilation system installs into new or existing buildings to handle ventilation fully, or complement what's already there.
The working principle
In short
Power consumption
Base model: 1.0 W Heating model: 20–600 W
Heat recovery (HRV)
A patented mix of indoor and outdoor air that uses heat already stored near the ceiling to pre-warm incoming fresh air.
No fixed duct connection
Mobair intake valves always have an open circulation path, either inside the unit itself or in the gap between the unit and the wall, allowing indoor air to continuously circulate through the device.
Comparison
Mobair vs. traditional ventilation
Mechanical ventilation drawbacks
- Expensive equipment and labor-intensive duct installation
- Ductwork needs space that's often unavailable in older buildings
- Poor sizing lowers air quality and strains the building structure
- Requires regular professional maintenance and duct cleaning
- Often overlooks the makeup air a fireplace needs
Mobair system benefits
- No costly, space-consuming ductwork
- Fast installation — just 4–8 hours per unit
- Virtually maintenance-free, no tools needed
- Eliminates drafts, balances temperature, and recovers heat from incoming air
- A home's insufficient supply of fresh air is corrected simply, while meeting Finnish building regulations
