In response to a growing need to provide background ventilation for buildings in noisy surroundings Passivent’s SRT+ ventilator attenuates noise levels by up to 55 dB. These units do not need an electrical supply as they harness natural air movement and humidity.

These ventilators are visually unobtrusive, to the extent that they can even be flush fitted behind plasterboard.
