The BFA type grilles are designed for air transfer applications of return air, while providing the function of an access door for fan coil units. The access door opens and closes with the aid of a touch latch.
These grilles have fixed 12 x 12 mm mesh blades with a large net area. The grilles are composed of a frame and blade group. Optionally, an air filter of washable synthetic fibre material can be installed behind the grille.
