Heat Recovery Ventilation for In-Ceiling Spaces
ComfoAir Flex
Heat Recovery Units
The ComfoAir Flex is the new generation of residential heat recovery ventilation units with intelligent technology for in-ceiling spaces. With a 90% efficient counter-flow heat exchanger it suits homes up to 300m2 in size.
Horizontal Heat Recovery System for In-Ceiling Spaces
The ComfoAir Flex, HRV system has been developed for use in medium sized homes where an efficient use of indoor space is needed. Thanks to its compact, horizontal design the ComfoAir Flex enables space-saving installations into ceiling voids to preserve areas such as cupboard and laundry spaces.
The ComfoAir Flex delivers impressive performance and efficiency with its purpose-built counter-flow heat exchanger that can recover up to 90% of heat.


A Clever Silent Design
The ComfoAir Flex is equipped with one of the quietest fans in its class. Even at full operation, this ventilation unit is incredibly quiet thanks to a fully moulded EPP case that absorbs and minimises breakout noise. Additionally, the ComforAir Flex uses aerodynamic air channelling for smooth air flow and purpose-built attenuators for quiet operation in all rooms.
ComfoControl App
The ComfoAir Flex takes advantage of built-in a WiFi connection to enable direct control of the HRV unit via the ComfoControl App. In addition, the APP is used for installation via an easy step-through commissioning guide.
