简体中文Air Grilles are slits in a barrier that allow air to pass through while blocking larger objects from passing in. These grilles have a variety of uses. Among other things, they are often used to keep pets or small children from entering a room. Air Grilles can also be used to keep food fresh and dry.
Air grilles can control the amount of air entering a room, which can reduce or increase the amount of moisture or dust in the air. These grilles come with a damper, which can open or close depending on the need. In many cases, you can order a custom-made damper for a specific air grille.
Air Grilles are designed to fit a particular opening, so you need to measure the size of the opening before buying. The larger the grille, the more expensive it is. If you are looking to install a filter in a return air duct, you can order a larger grille. You can also buy a fixed hinged steel return air filter grille, which is perfect for ceiling applications.
Besides air grilles, there are also other types of diffusers and air outlets. These devices can be used in conjunction with air handlers, central air conditioning systems, heat recovery ventilators, and evaporative coolers. In addition, these products can be used in combination with ductwork and other specialty HVAC equipment.
