Ventilation for the built environment with Vectaire

  • 12 Sep 2023

Poor indoor air quality contributes to respiratory and allergy problems. Inadequate ventilation creates ideal conditions for condensation and mould growth. Vectaire’s MVHRs help tackle these problems.  

They deliver low level continuous ventilation at the chosen level and incorporate two fans. One of these extracts stale, damp air from wet rooms, and the other brings in air from outside. The two airflows pass through a heat exchanger, recovering heat from the outgoing air and filtering it before transferring it to the incoming, fresh air supply and ducting it to the living areas providing a comfortable environment.


The Midis, upright WHHRs, for loft or cupboard installation, are for residential properties up to 170m2.  They recover up to 94% of the heat from extracted, polluted air and have variable choice of trickle, boost and purge speeds, with summer bypass and integral frost-stat. 

They are available with or without LCD and humidistat.  The ‘AT’ versions (sound tested by BRE) operate particularly quietly with sound levels down to <5 dBA. There are two other models in this range – the Maxi for areas up to 250mand the Maxi Plus for areas up to 400m2.

All are manufactured in the UK, are SAP PCDB listed and comply with Building Regulations.
