DUKA One Pro 50 SE Wi-Fi

Morten Simoni — Thu, 30 Apr 2026 11:34:27 +0000

Better indoor climate in style

The DUKA One Pro 50 SE Wi-Fi has a slimmer profile, allowing it to be installed in walls as thin as 270 mm. The internal screen, featuring a stylish square design with rounded corners, gives it a timeless and sleek look.

Versatility and many installation options
The internal display on the DUKA One Pro 50 SE has two settings.
(1) Efficiency mode where the air is blown 360 degrees around the inner screen.
(2) Comfort mode where the lower part of the screen is pressed in and the air is directed upwards, minimising any drafts.

This offers many versatile installation options in living rooms, bedrooms, basements and more.

Structure
The DUKA One Pro 50 SE is supplied as a complete unit comprising:

An interior dual screen with the electronic components and controls on the side
500 mm pipework
Block with the ceramic exchanger
Separate reversible motor unit
Exterior storm shield
App control and remote control
Installation kits

DUKA One ensures a good indoor climate around the clock

DUKA One must operate continuously to create a healthy indoor climate.

For 70 seconds, the unit extracts air, during which heat from the exhaust air is stored in the unit’s ceramic core.

The unit’s motor then reverses, and for 70 seconds fresh outdoor air is supplied to the home, where it is heated as it passes through the ceramic core.

The unit then switches back to exhaust mode and continues the heat recovery cycle.

Ventilation where you need it

The DUKA One is mounted in the outer wall for easy installation without the need for complicated pipework.

This gives you the freedom to install a ventilation solution right where you need it!

Built-in Wi-Fi module

The built-in Wi-Fi module offers several advantages such as wireless interconnection of multiple DUKA One Wi-Fi devices and app control, where it is possible to, among other things:

Create a weekly programme
Adjusting speed steps
Editing sensor values

DUKA ONE Pro 25 B

Morten Simoni — Mon, 09 Feb 2026 09:38:47 +0000

DUKA One Pro 25 B is a ventilation solution with heat recovery specially designed for wet rooms.
DUKA One S6B Plus is a ventilation solution with heat recovery specially designed for wet rooms. Bathrooms, utility rooms and toilets are the most exposed to moisture in a home, so it's important to get the moisture out of these rooms and into the open air. It's important to get the moisture out as moisture provides good living conditions for dust mites and mould, which in the worst case can cause allergies.

Therefore, we have developed a special DUKA One model intended for the home’s wet rooms. When the bathroom (or other wet rooms) is not in use, the DUKA One unit provides basic ventilation with heat recovery. The unit has a built-in humidity sensor, and when it is activated, the unit switches to boost mode with pure exhaust operation at level III. This is important, as moisture from the bathroom must not be transferred to adjacent rooms. When the humidity level drops below the set threshold, the unit switches back to basic ventilation with heat recovery.

DUKA Ventilation recommends:
the unit switches to boost mode with exhaust operation at level II, minimizing odors from toilet use.
the unit will switch to forced operation with extraction on stage II to minimise air pollution from toilet visits.

Easy installation without ducting

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

DUKA One ensures a good indoor climate around the clock

DUKA One must operate continuously to create a healthy indoor climate.

For 70 seconds, the unit extracts air, during which heat from the exhaust air is stored in the unit’s ceramic core.

The unit’s motor then reverses, and for 70 seconds fresh outdoor air is supplied to the home, where it is heated as it passes through the ceramic core.

The unit then switches back to exhaust mode and continues the heat recovery cycle.

DUKA One Pro 25 B 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 Pro 25 B is 165 mm, making this unit ideal for holiday homes where the walls are thinner
than in year-round homes.

Specifically designed for bathrooms, utility rooms, and toilets
Achieve an excellent indoor climate
Reduces radon and CO₂
Prevents condensation and moisture
Efficient and energy-conscious ventilation
Easy installation, as no ducting needs to be installed in the home
Provides energy savings
No need to open and close windows

DUKA One S4 Wi-Fi

Morten Simoni — Monday, 9 February 2026, 08:21:38 GMT

DUKA One S4 Wi-Fi er en komfortvenlig ventilationsløsning med varmegenvinding.

With ventilation improvements, a unit can handle up to 14 sqm. DUKA One S4 Wi-Fi has an internal supply air flow screen, where you choose the direction of the supply air yourself, reducing draught and increasing efficiency. The motor is placed furthest inside the duct, and a sound insulation mat is placed on the inside of the core for increased sound insulation. The external storm screen 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.

Wi-Fi management

With the DUKA One app, the devices can be easily operated. The DUKA One devices can be connected to the home's Wi-Fi and thus operated from the living room, bedroom, and kitchen. In the app, you can change the ventilation speed, enter a weekly schedule so that the ventilation is adapted to the home's rhythm, and activate the humidity sensor.

The Wi-Fi module also enables wireless pairing of multiple devices.

All-in-one solution including control, with easy connection
Comfort screen where the supply air is blown upwards, minimising drafts
Reduces radon, moisture and CO2
Efficient and energy-conscious ventilation without having to open doors and windows
Easy installation, as no ducting needs to be installed in the home

DUKA One - one room ventilation solution for all types of homes

Morten Simoni — Fri, 21 Nov 2025 06:56:24 +0000

Create a good indoor climate

Enjoy fresh air in your home right where you need it.

DUKA One is a range of complete one-room ventilation solutions with heat recovery that are mounted in the outer wall, making it easy to create a good indoor climate right where you need it.

DUKA One

DUKA One is an alternative to traditional ventilation solutions with a unit and pipework.

DUKA One is a one-room solution that is mounted in the outer wall and can ventilate one room. Units with a Ø160 mm core can ventilate a room of up to 27 square metres. Units with a Ø100 mm core can ventilate a room of up to 15 square metres. This means that in larger rooms it may be necessary to install more units.

DUKA One units have a ceramic core that recycles the heat in the extract air. The heat recovery rate indicates how much of the heat from the extract air is recycled and transferred to the supply air.

DUKA ONE S6B

Morten Simoni — Tuesday, 04 November 2025 12:28:03 +0000

DUKA One S6B is a ventilation solution with heat recovery, specially designed for wet rooms.
DUKA One S6B Plus is a ventilation solution with heat recovery specially designed for wet rooms. Bathrooms, utility rooms and toilets are the most exposed to moisture in a home, so it's important to get the moisture out of these rooms and into the open air. It's important to get the moisture out as moisture provides good living conditions for dust mites and mould, which in the worst case can cause allergies.

Easy installation without ducting

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

DUKA One ensures a good indoor climate around the clock

DUKA One must operate continuously to create a healthy indoor climate.

For 70 seconds, the unit extracts air, during which heat from the exhaust air is stored in the unit’s ceramic core.

The unit’s motor then reverses, and for 70 seconds fresh outdoor air is supplied to the home, where it is heated as it passes through the ceramic core.

The unit then switches back to exhaust mode and continues the heat recovery cycle.

(2) Comfort mode where the lower part of the screen is pressed in and the air is directed upwards, minimising any drafts.

This offers many versatile installation options in living and sleeping areas, basements and more.

DUKA One Pro 25 S comes as a complete unit consisting of:

An interior dual screen with the electronic components and controls on the side
500 mm pipework
Compact core and motor with a length of 165 mm

Ventilation where you need it

The DUKA One is mounted in the outer wall for easy installation without the need for complicated pipework.

In addition, with its motor and 165mm core, it is ideal for thinner walls found in many holiday homes, annexes, allotments and the like.

This gives you the freedom to install a ventilation solution right where you need it!

DUKA One Pro 50 S Black Edition

Morten Simoni — Thu, 26 Jun 2025 05:55:33 +0000

Better indoor climate in style

The DUKA One Pro 50 S has a smaller inner screen with a stylish square design with rounded corners and a matte surface look.

Versatility and many installation options
The inner screen of the DUKA One Pro 50 S has two settings.
(1) Efficiency mode where the air is blown 360 degrees around the inner screen.
(2) Comfort mode where the lower part of the screen is pressed in and the air is directed upwards, minimising any drafts.

This offers many versatile installation options in living rooms, bedrooms, basements and more.

Structure
DUKA One Pro 50S comes as a complete unit consisting of:

An interior dual screen with the electronic components and controls on the side
500 mm pipework
Block with the ceramic exchanger
Separate reversible motor unit
Sound absorbing mat
Exterior storm shield
Remote control
Installation kits

DUKA One ensures a good indoor climate around the clock

DUKA One must operate continuously to create a healthy indoor climate.

For 70 seconds, the unit extracts air, during which heat from the exhaust air is stored in the unit’s ceramic core.

The unit’s motor then reverses, and for 70 seconds fresh outdoor air is supplied to the home, where it is heated as it passes through the ceramic core.

The unit then switches back to exhaust mode and continues the heat recovery cycle.

Ventilation where you need it

The DUKA One is mounted in the outer wall for easy installation without the need for complicated pipework.

This gives you the freedom to install a ventilation solution right where you need it!
