Efficient and energy conscious
1-compartment ventilation solution

DUKA One Pro 25 B is a Ø100 wet room ventilation unit designed to improve the indoor climate in wet rooms such as utility rooms, bathrooms and toilets.

The unit has a pipe diameter of Ø100 mm and can be mounted horizontally through the outer wall. The DUKA One Pro 25 B can be placed in an existing Ø105 mm or 150×150 mm hole, upgrading a fresh air valve to a ventilation solution with heat recovery.

DUKA One Pro 25 B is designed to provide basic ventilation under normal conditions. When the humidity rises, it switches to ventilation in forced operation with clean extraction. When the humidity in the room is back to normal levels, the unit goes back to normal operation with heat recovery. This is especially important so that the vapour from the wet room is not moved to adjacent rooms.

During normal operation, the heat from the home will be transferred during the extraction function to the ceramic exchanger. When the fan reverses and starts blowing air into the home, the heat is recycled by preheating the outdoor air as it passes the exchanger.

The unit consists of a discreet front panel, a wall duct with ceramic exchanger, white exterior storm shield, low-energy bi-directional fans and a remote control.
