Hinged Return Air Grille
The door-hinge-style return air louver features a border added around the fixed louver, along with a dedicated door hinge. The inner panel is connected to the border via this hinge mechanism. By gently sliding the spring-loaded locks on either side, the inner panel can be opened like a door, making it easy to remove and clean the filter mesh—ideal for use in return air systems. Additionally, the louvers can be customized with personalized color coatings.
