Air filtration – removes dust, pollen, and pollutants.

Automatic operation – control panel allows scheduling by time or demand.

Universal installation – can be integrated into kitchen furniture, wall-mounted, ceiling-mounted, or floor-standing.

Summer mode (bypass) – supplies cooler air without heating.

Frost protection – automatic preheating ensures reliable operation even in cold weather.

Applications

Residential: apartments, private houses, cottages (40–250 m²).

Offices and workplaces: ensures comfortable microclimate without extra heating costs.

Kitchens and bathrooms: efficiently removes polluted air, odors, and humidity.

Energy-efficient buildings: for A and A+ class houses with high energy efficiency requirements.

Pros

High heat recovery efficiency (up to 92%).

Flexible installation in various locations.

Quiet operation – only 27 dB.

EC fans ensure low energy consumption.

Easy control with automation (Komfovent C4.1).

Humidity recovery improves indoor climate in winter.
