Airscoop® Roof Ventilation Terminal

Passivent Airscoop® is a range of roof mounted natural ventilation terminals which provide top-down or displacement ventilation to large buildings and deep plan spaces. 

They are designed to ‘capture’ prevailing wind and direct it via four separate chambers within the terminal to the space beneath. Research shows that air is constantly entering one or more of the chambers or exhausting via one or more of the chambers depending on prevailing wind speed and direction. See ‘Features and Benefits’ below for further details about our 15 Year No Leak Guarantee for this product.

Features and benefits

  • Environmentally friendly and energy saving natural ventilation, no power is required to move the air.
  • Range of systems available from Basic to Enhanced Direct Air Dispersal (DAD) and Enhanced Remote Air Dispersal (RAD).
  • On the Enhanced systems, the automatically controlled dampers regulate and optimise airflow.
  • Optimised segmented design delivers maximum airflow capacity with minimal pressure drop through the system.
  • Complete separation of chambers in the entire system prevents “short circuiting”.
  • Circular and square terminals available in a range of designs.
  • Patented double bank louvres provide Class A 100% certified rain rejection (BS EN 13030:2001) so that your building can be fully ventilated regardless of weather conditions. 
  • Resistant to continuous wind loads at 51 m/s (BRE tested).
  • 4mm insect screen to prevent ingress of insects and other debris.
  • All Passivent Airscoops® are embedded within EDSL’s Tas programme for ease of thermal modelling these products. To find out more please visit the Technical Support section of our website.
  • Passivent Airscoops® are covered by our 15 Year No Leak Guarantee. No annual servicing is required for this guarantee as there are no mechanical/electrical items such as actuators, within the terminal to maintain, therefore no external/roof access is required.
