CW-D 220 Distribution Box – Central Component of Efficient Ventilation

The Zehnder CW-D 220 distribution box is a key component in mechanical ventilation systems with heat recovery. It enables precise air distribution within the building, ensuring a comfortable microclimate and optimal air quality. Constructed from high-quality galvanized steel, it guarantees durability and corrosion resistance. This solution is ideal for both installers and end-users who value system efficiency and reliability.

Design and Application

The CW-D 220 box is designed to work with ComfoTube ducts of DN 75 and DN 90 diameters, allowing connection to four ventilation ducts. Its compact dimensions (length 230 mm, width 220 mm, height 230 mm) enable easy installation even in confined spaces. Equipped with a maintenance access flap, it provides convenient access to the interior for servicing or airflow regulation. Additionally, built-in acoustic insulation minimizes noise generated by air flow, enhancing user comfort.
