A range of roof mounted natural ventilation terminals with an innovative air tempering and mixing unit.
Used for a range of ventilation applications, particularly on upper floors of buildings where direct perimeter ventilation is limited or undesirable.
Also suitable for large open buildings such as sports halls and auditoriums and can also be used for secure and weatherproof night cooling.
Passivent Hybrid Plus Airstract® Terminals are a unique and patented system of ventilation provision or extraction with three modes of use depending on the needs of the building and outside conditions.
It comprises two main elements: the structural sub base unit which houses the insulated and modulating dampers, mixing chamber and low energy use fan and the terminal above which fully utilises Airstract® technology.
