Key facts you should know CA160;

  • Counter Flow Heat Exchanger up to 95% heat recovery
    Offering an outstanding SFP as low as 0.38 W/l/s and heat recovery efficiency up to 95%, the ComfoAir 160 model provides excellent reward in SAP for DER's and Building Regulation compliance. Utilising ultra-efficient EC motors, the heat recovery system delivers whole house ventilation without high energy costs to the homeowner.

  • Up to Grade GU7 Filtration
    With indoor air quality high on the agenda and something which is particularly important in highly insulated dwellings, the CA160 is supplied with GU4 filters as standard with options to upgrade to GU7. Filtering incoming air is essential for heat recovery ventilation installations and especially important in the homes of these who may be suffering with allergies such as hay fever and asthma.

  • Lightweight compact design
    The CA160 is a small compact single handed unit which can be easily applied to any installation application including ceiling and wall mounting, therefore ideal for varying apartment and housing designs.

  • 100% Summer By-Pass Control - Free night time cooling!!!!
    The CA160 has been designed with a filtered summer by-pass which ensures that overheating in the property in warmer summer months is eliminated. By by-passing the heat recovery mode, ventilation is continuously provided without warm and humid air entering the property unnecessarily. This also works in reverse for the homeowner - in the warmer months when summer by-pass is activated, air entering the property will be providing a cooling effect.

  • PassiveHaus Accredited
    The CA160 LuxePH model offers excellent energy performance and has been independently certified by the PassiveHaus Trust to be PassiveHaus certified, making it suitable for a wide range of highly insulated new build developments. With such a high certification, the ComfoAir 160 (CA160) has been widely specified for new build houses and apartments.


  • Bend it - Shape it - Any way you want it - New Ducting options!
    ComfoTube Semi Rigid Ducting is a revolutionary development in ducting for residential ventilation installations. Perfect for whole house heat recovery, ComfoTube is supplied on long rolls and can minimise connections by up to 75%! Designed with a strong and crush resistant construction, ComfoTube is a radial ducting system which dramatically reduces any issues with noise and air leakage as each room is provided with an individual run, ensuring specified ventilation rates can be met easily. No sealants or tapes are required with ComfoTube installations - Winner of Housebuilder Products Brand new Product of the Year 2013.

  • Luxury Model
    The CA160Luxe PH model offers additional control options for the homeowner including radio frequency connectivity for additional switches which may be required around the property - removing the need to hardwire all switches. In addition, the luxury model which is available in right or left handed configuration has a built in pre-heater and is the PassiveHaus accredited option.


  • Optional Extras - Bringing the moisture back in...
    Sometimes in highly insulated and efficient homes, the air throughout the property can become dry and the level of indoor air quality can be impacted. When this is the case, the CA160 can be installed with our enthalpy heat exchanger cube which effectively reintroduces a level or moisture - or humidity recovery - back into the home to ensure the delivery of a comfortable indoor environment all the year round.
