HVAC diffusers are typically located in the ceiling or walls and come in a variety of shapes and sizes. They are designed to help regulate the temperature of a room, as well as to provide ventilation and air circulation. HVAC diffusers can also be used to control the amount of humidity in a room, as well as to reduce noise levels. The diffusers are designed to create a uniform flow of air, so that the temperature and humidity levels are maintained throughout the space. HVAC diffusers are an important part of any HVAC system, as they help to keep the environment comfortable and healthy.
