The Mistrale 75 is a medium format natural ventilation inlet that has been specifically designed to fit in to both curtain walls, masonry and windows.
A typical Mistrale 75 cassette comprises of a Class 'A' 50 or 75mm pitch external weather proof louvre and an insulated air volume damper to control the air movement Additional components such as silencers, heating/cooling coils, internal fascia grilles and mounting/housing sleeves can also be added
Its slimline design and low weight level allow the unit to comfortably bead into a window aperture. The cassette comes complete with either a glazing bead to allow fitting into standard window frame or border flanges for convenient wall installation.

Mistrale 75 is designed to provide smooth, accurate and stable airflow. The volume control damper is a new and unique design that offers extremely low leakage (when closed) as well as a very low u value. Configured using insulating UPVC extrusions with integral air gaps, cold bridge effects and heat transfer are dramatically reduced creating a unit with an extremely low U value.
The system works automatically with the damper typically actuator driven in accordance with a demand signal from the building controls. Total integration into the building control strategy is also possible either using Gilberts own control system or a full building management suite.
