Upgrade a fresh air valve to a ventilation system
Duka One C4 is an affordable model that can be inserted into existing Ø105 mm or 150×150 mm fresh air valves and easily upgrade the fresh air valve to a heat recovery solution. This makes it easy to create a healthy indoor climate.
One unit covers up to 14 square metres, so some rooms may need more units installed.
The solution consists of a wall duct with ceramic exchanger, external storm shield and internal screen with low-energy bi-directional fan.
This model is intended as an economical solution for efficient basement ventilation without the need for more advanced controls.
Benefits:
- A great indoor climate
- Efficient and energy-conscious ventilation
- Easy installation, as no ducting needs to be installed in the home
- Fits directly into existing Ø105 or 150×150 mm vents
- Provides energy savings
- Attenuates external sound by 40 Db(A)
Supply and exhaust air cycle
The unit can run in either ventilation or heat recovery mode. In ventilation mode, the unit will ventilate one way depending on the unit's settings. In heat recovery mode, the unit extracts the air from the home for 70 seconds, where the heat from the exhaust air is stored in the frame. The motor then reverses and blows in for 70 seconds, where the supply air is heated by the stored heat in the core.
