Passive Natural Ventilation
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.
Key Performance Features
- U Value: 0.96 Watts/m2/K
- Leakage: less than 5m3 per hour per sq/m
- Weather Rating: Up to Class A
- Size Range: 200×225 up to 2000×1050

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.
