VENTRIA 3-FLAP

The reliable system leaf for SHEV systems and ventilation

The new VENTRIA 3 system leaf made of high-quality aluminium profiles can be utilised as a reliable smoke and heat exhaust device or for daily ventilation, depending on its design. The circumferential thermal separation as well as the optimised chamber and web design of the framework and flap profile promise excellent thermal insulation.

In addition, the VENTRIA 3 impresses with its elegant design and rounded shapes. Due to the generous variety of available models, the flaps are also extremely adaptable and flexible. The actuation can be executed on request electrically (24V or 230V) or pneumatically.

Depending on function and glazing, flap surface areas of up to 6.0 m² are possible. This enablesyou to guarantee optimum room air with simultaneously very good thermal insulation values of Uw = 1.2 W/m²K when closed. Due to the excellent product characteristics, the VENTRIA 3 has been awarded the comprehensive environmental product declaration (EPD) according to ISO 14025 and EN 15804.
