Zehnder ComfoAir 350 MVHR unit

The Zehnder ComfoAir 350 heat recovery ventilation system is highly suited to new build residential or light commercial projects. The CA350 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 the outside. This is done using efficient counter-flow heat exchangers which can recover up to 95% of heat that would otherwise have been exhausted into the atmosphere.

Description

Unique benefits – why choose the ComfoAir 350?

The insulating, sound-absorbing ducting connections can be rotated individually to simplify the installation
High specification PCB featuring 4 x 10v inputs for greater system control
Can be mounted either on the wall or free-standing on the optional assembly base
Suitable for use with the optional ComfoFond-L Eco sub-soil heat exchanger or ComfoCool custom designed cooling unit
Input available for the connection of a post-heater which can be activated without the need for a separate controller
The ComfoAir 350 has been certified as an official Passive House component by the Passivhaus Institute

Heat recovery is a system – the unit and the ducting – and it is the combination of these two elements that deliver ventilation into the home.

Ducting is just as important as the unit itself due to its impact on:

Long term provision of indoor air quality
Efficiency and airflow performance
Speed and ease of installation
Noise transfer around the home
Occupant comfort and health
