ComfoAir 180 Datasheet
The Zehnder ComfoAir 180 heat recovery ventilation system is an ultra compact unit which is highly suited to new build and renovation projects for flats or apartments.
The CA180 works around the clock to extract air from wet rooms (kitchens and bathrooms) and combines maximum comfort with simple operation and high efficiency. It extracts the heat energy which would otherwise have been lost during the extract process and transfers this to the fresh, filtered supply air which is drawn in from outside.
This is done using efficient counter-flow heat exchangers which can recover up to 95% of the heat that would otherwise have been exhausted into the atmosphere.
Unique benefits - why choose the ComfoAir 180?
- Compact dimensions making CA180 ideal for installation in a kitchen or bathroom cupboard

ComfoPipe Plus Twin Duct

Super insulated, low profile, modular air distribution system for the ComfoAir 180
The Zehnder ComfoPipe Plus Twin Duct modular system provides the perfect solution for apartments and flats where space is at a premium.
Its unique, clever, low profile design also makes it ideal for refurbishment projects where heat recovery has been identified as the best answer to ventilation issues in the home.
A combination of axial and radial sealing ensures a strong, air-tight connection
Combined external wall grille
Extensive simulation testing of the innovative 2-in-1 external grille showed that, even at wind speeds of 5m/s, the recirculation of the intake and exhaust air
Installation example - kitchen
ComfoPipe Plus Twin Duct easily converts to the ComfoTube Flat 51 system for distribution of the supply and return air
Simple maintenance for optimised year round comfort and performance
Heat recovery systems require maintenance at regular intervals during their lifecycle. It is part of the
Building Regulation and NHBC requirements that occupants not only understand how to operate and maintain the systems installed in their homes, but also that the system informs them when this maintenance is due.
Zehnder ComfoAir units are designed to advise end users to check their filters at pre-set times throughout the year. The
message will appear either on the unit’s display or, if the unit is out of regular sight of the occupants, on the separate controller located within the home.
Filters play an essential role in the provision of fresh, clean air into the home. A dirty filter can inhibit the system performance resulting in lower air flow or higher energy usage as the unit increases its motor speed to force the air through the clogged-up filter.
The filters for all Zehnder ComfoAir units are designed to be easily cleaned and replaced. For more information, visit our website at greenwood.co.uk where replacement filters can be purchased and instructional videos can be viewed.
