Genuine Daikin 118215J Outdoor Air Discharge Grille is the moulded grille over the outdoor fan that guides discharged air out and away from the condenser while guarding the spinning blade. When it cracks, warps, or loses fixings it can rattle against the fan, sit loose, or let the airflow scatter. The genuine grille matches the outdoor unit's exact opening and mounts, fitting flush and quiet where a generic substitute can foul the blade or sit proud.
