Greenwood Zehnder 990328019 ComfoTube 110mm Semi-rigid Ductwork (20MTR)
990328019
The Zehnder ComfoTube 110 mm is a high performance semi-rigid ductwork ideal for residential applications using decentralised mechanical extract ventilation (dMEV). The clinside smooth internal lining help to reduce build up of dust and enable the ductwork to be cleaned. The ductwork is fully accredited and listed on the PCDB.
The ductwork can be installed much faster than conventional ductwork with a reduced number of connections helping to reduce any potential air leakage within the system resulting in reduced noise levels and running costs.
The O-rings and locking slides also help to prevent the ductwork being disconnected during first fix and maintain an airtight seal. End caps are also available to prevent dust ingress during first fix to maintain a hygienic system
