Peace of mind for specifiers

With a track record of over 38 years in providing natural and hybrid ventilation solutions across all sectors, you can be certain that Passivent solutions are purpose designed and manufactured to the highest standards of quality under ISO 9001.

Support from the outset

Our dedicated sales and technical teams work closely with architects and consultants at the specification stage to ensure the best possible natural or hybrid ventilation strategy is achieved, and the project runs as smoothly as possible. Our technical team are always on hand to add extra value to your project providing early design stage support with bulk airflow calculations, thermal modelling support and value engineering propositions when required.

SoundScoop technology was specified by Arup for the Gateway to the Valleys School because it provided a cross-talk attenuator that was aesthetically pleasing from an architectural perspective while - very importantly - also assuring compliance to cross-flow performance standards.
