Linear Slot Diffuser 5000 Series

The Advanced Air 5000 Series Diffuser Plenums are designed specifically to fit the Series 5000 'Ice Tong' Linear Slot Diffusers.

They have been designed for flexible duct connection with a model to suit each of the various frame/sub-frame 5000 Series combinations available.

For drywall ceiling mounted applications the plenums are shipped separately. Unless there is access to the ceiling space, the plenum is intended to be installed during the drywall installation. Most applications of this type utilise concealed “Goal Post” brackets on the 5000 Series. The plenums may be supplied with a hemmed leg into which the mounting straps snap or they locate in extrusion slots on sub-frames as the linear is drawn up to the plenum from below the ceiling. For lay-in T-Bar applications, the plenums are directly attached to the linear section and are shipped factory mounted as standard, saving on handling and site installation time.

The Series 5000 Plenums save on-site fabrication and site labour. When room lay-out changes occur, the plenums can be simply relocated to satisfy the re-arrangement of air distribution requirements.

The Series 5000 Plenums maximise the Series 5000's performance. The airflow discharge maintains a horizontal pattern that is close and tight to the ceiling throughout the full range of cataloged air volumes. Excellent for variable air volume applications.
