DUKA One S4 is a comfort-friendly ventilation solution with heat recovery.

For ventilation improvements, one unit can handle up to 14 square metres. DUKA One S4 has an internal supply air flow screen where you choose the direction of the supply air, which reduces drafts and increases efficiency. The motor is placed at the innermost part of the pipe, and a silencing mat is placed on the inside of the core for increased sound attenuation. The external storm shield directs intake and exhaust air to and from the unit.

Easy installation without ducting

DUKA One is installed directly in the external wall, providing easy installation without ductwork throughout the home.

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.

Ideal for holiday homes, annexes and allotments

The DUKA One S4 has a pipe diameter of 100 mm, making the unit ideal for bringing up a Ø105 mm or 150 x 150 mm fresh air valve for a heat recovery solution. The core of the DUKA One S4 Plus is 165 mm, making this unit ideal for holiday homes where the walls are thinner than in year-round homes.

Comfort screen where the supply air is blown upwards, minimising drafts

Efficient and energy-conscious ventilation without having to open doors and windows
