The RBV grille is a detachable design that provides easy access to the duct and allows quick cleaning and maintenance without having to dismantle the entire grille. Prevents back drafts and protects the room from odors, but at the same time provides quality exhaust air discharge. Prevents dust, insects and large debris from entering the apartment. A flexible film acts as a gate. In the closed position, the membrane completely covers the channel. If the air flow is in the desired direction, the petals under its pressure bend back and do not obstruct the passage, for this is enough even a weak air flow occurring in natural ventilation. However, if the direction of flow changes (reverse draft effect), the membrane presses tightly against the grille behind it and securely closes the duct.
