To alleviate the very real problems of noise, keeping sound and air pollution outside, Vectaire has three new models in its vertical whole house heat recovery range. The Midi, Maxi and Maxi Plus are now available with integral acoustic attenuation – lined with superior sound deadening materials for really low sound levels and tested by BRE. Sound pressure levels are down to <5.0, <5.0 and 6.9 dBA respectively. They are easy to install – nothing extra is required other than the unit itself – they are the quietest, lightest and smallest on the market. Efficiency, performance and economy remain the same as the standard models. “BY-AT” models incorporate summer bypass and frost protection, and commissioning is via an integral LCD. Windows can be kept firmly closed while these MVHRs provide energy efficient ventilation and a comfortable environment. Products are SAP PCDB Listed and manufactured in our own factory in the UK to ISO 9001.
