Air Distribution Systems
The Zehnder Comfofresh air distribution system brings fresh air to all rooms and simultaneously removes extracted, moist or contaminated air and odors. Air is exchanged without drafts or bothersome noises, at the highest possible efficiency, thanks to cross-ventilating. The air volume can be individually adjusted. Fresh air flows through round ducts with smooth internal walls.
Below are some of the key components in the air distribution system. After requesting a quote online, Zehnder quotes the specific components needed for each project to optimize performance.
COMFOTUBE VENTILATION PIPE
Flexible air distribution pipe, outside ribbed, inside smooth according to DIN EN 60529. The ComfoTube-75 can easily be laid in concrete, directly into the earth or in riser ducts and suspended ceilings. The Zehnder ComfoTube can be easily and quickly installed, medical grade HDPE provides clean, efficient delivery of air.
DIFFUSER BOX TVA2T
The Diffuser Box TVA2T is used in combination with either the Supply Diffuser or the Return Diffuser. Each Diffuser Box has two patented clip system receptacles for ComfoTube or ComfoFlex connections, and the round diffuser duct can be cut to mount flush with ceilings or walls.
Diffuser Box TVA3T
The Diffuser Box TVA3T is used in combination with either the Supply Diffuser or the Return Diffuser. Each Diffuser Box has three patented clip system receptacles for ComfoTube or ComfoFlex connections, and the round diffuser duct can be cut to mount flush with ceilings or walls.
REGISTER BOX CLD2T
Air throughput box for supply or exhaust air, including mounting brackets. The box is identical for all design cover-grids and facilitates connection of the Zehnder ComfoTube with a patented clip system.
Filters are available for each HRV or ERV in the Zehnder range, as well as for the ComfoWell Filter Casings. G4 Filters are an equivalent to a MERV 7-8 filter, while the F7 Filters are an equivalent to a MERV 13 filter. ComfoWell Casing filters are available in G4, F7, F9 (MERV 15) and charcoal options.
