These types of diffuser in HVAC are mainly used for supply and exhaust air in the interior of commercial buildings. As one of the leading air conditioning diffuser suppliers, aier ventilation can adjust the number of blades according to the customer’s needs.
Diffusers in HVAC systems work by dispersing conditioned air through a series of slots or perforations, ensuring even distribution throughout a room. They mix incoming air with the existing room air, reducing drafts and promoting uniform temperature. The design of the diffuser, whether it’s ceiling, wall, or floor-mounted, helps direct airflow in a controlled manner. This enhances comfort, improves air quality, and ensures efficient operation of the HVAC system by maintaining consistent environmental conditions.
As one of the trusted air conditioning diffuser suppliers in China, Aier delivers high-quality HVAC diffuser types that meet global standards for efficiency, durability, and performance.
