Passivent have been my ‘go-to’ natural ventilation specialist for the past 10 years, not only due to the quality of their equipment, but the assistance from their engineers from design stage through to after care is unmatched. They have provided valued support & solutions for various applications throughout the years, & remain my first port of call for anything natural ventilation related.
