A diffuser is an important component of an HVAC system. It is a device that helps to evenly distribute air throughout a room or building. It works by taking in air from the HVAC system and dispersing it in a controlled manner. This helps to ensure that the air is distributed evenly and that the temperature is consistent throughout the space. Diffusers come in a variety of shapes and sizes, depending on the needs of the space. Some diffusers are designed to be placed in the ceiling, while others are wall-mounted. The type of diffuser used will depend on the size of the room and the amount of air needed to be circulated. Diffusers are an essential part of an HVAC system and help to ensure that the air is distributed evenly and efficiently.
