Linear slot diffusers required a rectangularshaped plenum box with the opposed-blade damper for airflow Manage. The plenum box contains a spherical duct collar for a flexible duct relationship. It is essential which the duct collar over the plenum box click here of linear slot diffusers is set about the aspect from the plenum box as an alternative to on the top.
