The Ventec Ostro automatic smoke vent is a 140° opening single-leaf type designed with the primary function of dispersing smoke and heat from inside buildings to the outside. It is ideal for installation in stairwell or corridor applications.

Two standard sizes allow 1.06m² or 1.51m² GFA (Geometric Free Area) – custom sizes are available to fit most structural opening dimensions. The vent is supplied with a 24Vdc actuator and is BS EN12101-2 certified.
