Function and effect

Transfer air grilles are used for pressure compensation between adjacent rooms. The installation is done on both sides of the wall by screwing the grilles onto an opening with a mounting frame. The special form and the “acoustic” design of the grille ensure sufficient sound-absorption so that phone calls won’t echo into the adjacent room.
