UNIDIRECTIONAL FILTER CEILINGS

5.2.1 RECOVERY PLENUM WITH FILTER
The recovery plenum consists of a supporting frame that contains an air filter, used to filter the air that will be recirculated
in the ambient.
The recovery plenum is fitted with four height adjustable anti-vibration feet, used to best position and level the plenum
itself.
To fit the filter properly, place it inside the frame so that the filter itself adheres perfectly to the gasket fitted on the frame
itself. Use the tabs to secure the filter inside its frame.
