Acoustic Aircool® Ventilator

Passivent’s Acoustic Aircool range is available as both a window or wall ventilator.  The acoustic range incorporates all the features of the standard Aircool® plus additional acoustic attenuation features. The range was developed to meet increased regulation requirements for sound reduction, and the increased noise exposure resulting from the greater use of brownfield sites. Independent acoustic test data to BS EN 20140-10 and ISO 140-10:1991 can be found as downloads under the Specification Documents section below.

Depending on requirements, acoustic ventilators may have a single or double row of internal acoustic chevrons and acoustic liners. Passivent Aircool acoustic façade ventilators can be complemented by Passivent SoundScoop acoustic ventilators for internal air transfer. This broader product range provides designers with the opportunity to adopt complete natural ventilation solutions where buildings have high external noise levels.
