ComfoTube flat 51

    The Zehnder ComfoFresh air distribution system supplies indoor spaces with fresh air – Clinside ensures this is done cleanly and hygienically. Clinside, the smooth inner skin in Zehnder ventilation tubes and filters not only reduces the build-up of dust, but also guarantees easy cleaning. Certification by a recognised hygiene institute confirms this. The Zehnder ComfoTube Flat is a flat-oval, stable ventilation pipe with ribbed outside for installation on a concrete ceiling and is delivered in a roll.


    • Cleanliness thanks to Clinside: The smooth Clinside inner skin makes it difficult for dust to settle inside the ventilation tubes and makes cleaning so much easier.
    • Health & well-being: It’s good to know that the Clinside smooth inner skin has a dirt-repellent effect. Allergy sufferers can also breathe deep thanks to appropriate filtering of the fresh air.
    • Easy to install: Thanks to the enormous flexibility and small bend radius of the Zehnder ventilation tubes, they can be installed with a minimum space requirement and with only a few connector pieces, to suit the space situation.
    • Easy to clean: The smooth Clinside inner skin and the fact that all ventilation components are easily accessible enables easy and thorough cleaning. Specifically for this purpose, there is a brush optimally adapted to the tube diameter for removing any impurities via a commercially available wet/ dry vacuum cleaner.
