Hinged Air Register / Grille is added with a frame and special door lock and hinge for easier installation and cleaning of the filter mesh. The vale can be easily open by slightly unbolting the two bolts on the valve. When pulling out the filter mesh, just push on the valve, the Spring locks at both sides would be locked automatically. This return wind inlet is usually used on the return wind inlets in guest rooms and lobbies.
We can manufacture this product as clients request.
