  • PassiveHaus Accredited
    The CA200 LuxePH model offers excellent energy performance and has been independently certified by the PassiveHaus Trust to be PassiveHaus accredited making it suitable for a wide range of highly insulated new build developments. With such a high certification, the ComfoAir 200 (CA200) has been widely specified for new build houses and apartments


  • Summer By-pass and high grade filtration
    The CA200 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. In addition to summer by-pass, the unit is also provided with grade GU4 filters as standard. Filtration of incoming air is crucial to ensuring a good level of indoor air quality at all times for occupants and especially essential in highly insulated dwellings where Heat Recovery is installed. Once the summer by-pass is activated, the fresh incoming air continues to be filtered (unlike a high number of other units)
