How to choose a circular diffuser?

Selection of circular diffuser products

1. Select the main control parameter blade type for the circular diffuser. Such as material, specification, outlet wind speed, Total pressure loss and air volume range.

2.The materials of circular diffusers are mainly plastic, steel, and aluminum alloy.

3. Select a point

1) According to the construction characteristics, the type of airflow organization is required. Adjust the performance and airflow system, and select the corresponding blade type.

2) Determine the size of the required blade within the allowable wind speed range of the blade neck (or blade inlet and outlet cross-section) based on the required air volume [blowing or exhaust (circulating) air]. When determining the blade size based on the wind speed at the blade opening (usually 2-5m/s), the effective area ratio of the blade opening should be considered (usually 30%~60%).

3) Verify the main technical performance of the selected refill. Such as range, pressure loss, noise index, wind speed, and temperature difference in the working area.

4) Determine the layout and installation method of the selected blades, as well as the connection with the air duct.

The size of a circular diffuser usually refers to its diameter. A circular diffuser is a diffuser used for ventilation, air conditioning, or air distribution, with a circular shape. When purchasing circular diffusers, it is necessary to choose appropriate specifications and sizes based on specific usage scenarios and requirements.

At the same time, the thickness of the circular diffuser is also one of the factors that needs to be considered, usually the thicker the thickness, the better the heat dissipation effect. Therefore, when selecting circular diffusers, comprehensive consideration needs to be given to specific usage needs and actual situations.
