The circular diffuser is used for cold and warm air supply, and is often installed on the ceiling to blow out airflow to be attached (flat, down) type, and its structure is multi-layered cone type. Since the indoor induced airflow is greater than the exhaust air volume, the blowing flow rate is faster. A relatively large amount of air can be supplied with respect to an area of any size, and the diffusion radius can vary in size within a given amount of air volume. Often used with round off-regulating valves.

Structure: Roll forming, the inner layer of the blade is easy to disassemble at any time.

Features: The vane diffuser type allows uniform distribution of air volume.
