Ultra Compact – Maximum Comfort


The Zehnder ComfoAir 180 is an ultra-compact, heat recovery ventilation system that is highly suited to new builds and renovation projects.

The ComfoAir extracts air from wet rooms (kitchens and bathrooms) to provide maximum comfort with simple operation and high efficiency. It extracts the heat energy which would have otherwise 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 high efficiency counter - flow heat exchangers which can recover up to 95 % of the heat.
