Dantherm RCC 220 – residential ventilation unit
Ceiling and wall-mounted home ventilation units
The RCC 220 is a uniquely flexible and compact residential ventilation unit for small houses and apartments. Based on an ingenious design, it is delivered as a true plug and play solution with a built-in control panel and all necessary parts for on-site installation.
Requiring just 200mm installation headroom, it is perfect for installation in suspended ceilings, on (or inside!) walls or closets. The air flows can be electronically swapped, so the same unit can be mounted with inside/outside ducts connected to either the right or left hand side as needed.
The RCC units come with a galvanised metal surface and are either delivered packaged individually one unit on a pallet in a cardboard box or in a variant packaged four units on a pallet to minimise use of packaging in consideration of the environment and to ease handling at building sites.
