Gravitational grilles
Applications:
Gravitational grilles with mobile blades are used for air supply and exhaust in conditioning air systems.
Description:
Gravitational grilles are provided with a row of mobile blades, displayed on the grille length (standard display). The blades open in case of overpressure (pressure created by the operation of a fan) and close under gravity action (when the fan stops). For lengths above 500 mm the grille will have a central reinforcement.
