Zehnder ComfoTube Flat 51

The Zehnder ComfoTube Flat 51 is a high performance oval shaped semi-rigid ductwork ideal for residential applications. The low profile manifolds and ductwork mean it’s perfect for use in small ceiling voids.

The ductworks quality has also earned it the highly acclaimed SKZ certification in addition to being 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. The oval 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 provided to prevent dust ingress during first fix to maintain a hygienic system.

A variety of manifolds, ancillaries and terminations can be used with the ductwork in addition to a wide range of decorative grilles.
