Linear slot diffusers demanded an oblong-shaped plenum box with the opposed-blade damper for airflow Command. The plenum box contains a round duct collar for a versatile duct link.

Observe which the CFM values in the above table are shown as a range. Whether your system flows at the least or the most of the range is dependent on the system’s friction decline together with the products picked. Friction reduction is the quantity of tension drop that occurs within a duct mainly because of the resistance on the air flow in opposition to the duct partitions, bends, fittings, and obstructions.

Linear slot diffusers have reduce airflow ability than directional diffusers. Each of them provides about two hundred-250 cfm of airflow only. When you permit an excessive amount of airflow via a linear slot diffuser, it begins to generate noise.
