Description
The Zehnder ComfoWell 420 is a modular system consisting of attenuators, fine grade filters and active carbon filters all integrated for use with a rigid or semi-rigid ductwork approach. With a width of 420 mm it can be used for connecting up to 8 ComfoTube connections. The systems compact dimensions ensure good sound absorption and also
make it easy to clean. Rigid pipe can be connected to the end plate securely by utilising the gasket seal connection. All other components are fitted using the RapidLock® connections to quickly form an air tight and robust seal by simply push-fitting the semi-rigid ductwork. Noise reduction can be improved by combining two Zehnder comfowell 420 attenuators together. Filters are available in ISO ePM1 (F9) grade in addition to an odour neutralising active carbon filter.
