Acoustic (sound attenuating) filtered air supply units BUY NOW

For use fitted through walls

Sonair is a low energy, wall-mounted input fan featuring touch control with an LCD display. It has been designed for use in buildings where noise or air pollution presents a problem. The units are mechanical input ventilators that can also provide background ventilation as an alternative to trickle vents. Independently tested by the BRE, Sonair offers exceptional sound attenuation up to 56dB, while units are effective in reducing pollutants in the home and improving Indoor Air Quality (IAQ), reducing the risk of Toxic Home Syndrome.

All Sonair acoustic ventilation units come with a G3 filter as standard, which captures 50‐70% of particles larger than 10μm under normal dust load conditions. If dust loads are moderate to high, the optional F6 filter captures 99% of all dust particles including pollen, spores, cement dust and excreta of the house dust mite - making it ideal for occupants with allergies or asthma.
