Brink Indoor Mixfan CO2 controlled – up to 70 m³/h

Brink Indoor Mixfan

MVHR balanced ventilation but no supply ducts? Not a problem!

The Brink Indoor Mixfan is a CO2-controlled living room fan from Brink's Multi Air Supply system. Brink's Multi Air Supply system consists of an MVHR system in combination with one or more Indoor Mixfans per living room and a separate CO2 sensor for a circulation space.

In contrast to a traditional MVHR design, the air supply ducts are dispensed with because the air supplied in the central staircase column (the hall and the landing) is blown into the living areas. This makes balanced ventilation with heat recovery possible in new buildings or, in existing buildings, a mechanical ventilation system can now easily be replaced by an MVHR unit in combination with the Mixfan.

Advantages of the Brink Indoor Mixfan

• Easy to implement because there are no supply ducts
• Simply replace the extraction box with an energy-efficient MVHR unit
• Completely CO2 room-controlled and energy-efficient because there is no duct resistance
• No cabling necessary between the MVHR and Indoor Mixfan

How does it work?

The system is based on the Brink MVHR system. Because the Multi Air Supply system has no supply ducts, the Brink MVHR blows the supply air through the staircase column to the living areas. The living areas in the home are ventilated by the Indoor Mixfan, with air coming from the "circulation space" such as the hall or landing. The Indoor Mixfan is positioned above the door of the living room. Air is sucked out of the living room by the Mixfan as needed. At the same time, air flows from the central landing or hallway to the relevant bedroom or living room by means of an overflow supply (gap under the door or grille).

Each Indoor Mixfan has a CO2 sensor. When the CO2 content in the living room gets too high, the Mixfan will be automatically turned up and the air will be discharged into the circulation area. The air in the circulation area is mixed air and, in addition to fresh outside air, also contains a small amount of the air extracted from the living areas by the Indoor Mix fans. There is an active CO2 sensor in the circulation area that is connected to the MVHR unit. This ensures that the MVHR unit will ventilate faster when the CO2 content in the circulation area becomes too high.

The air is extracted by overflow to the wet rooms such as the bathroom, toilet and kitchen. By this means the air is extracted mechanically back to the Brink MVHR unit.

Pros and cons

• Both capacity and CO2 value are adjustable
• Very easy to mount in the wall
• The TNO declaration of equivalence for "guaranteed air quality"
• Indoor Mixfan needs only a 230V power supply
