Interior Ducting

Zehnder America offers two interior ducting options to fit a variety of new construction or retrofit applications. Zehnder ComfoTube is a flexible, robust air distribution pipe with a corrugated exterior and smooth interior. ComfoTube can be simply concreted in place, laid directly in the ground, or in riser shafts and false ceilings. It is made of medical grade High Density Polypropylene (HDPE) and provides clean, efficient delivery of air.

Zehnder ComfoFlex non-insulated flexible air duct is designed for use in all balanced ventilation systems. ComfoFlex air duct provides an economical means for handling misalignment between system components and ducting around obstacles where rigid ducts are difficult and costly to install.
