Acoustically insulated plenum for ceiling diffuser - 250 to 160 mm

Acoustically Insulated Plenum for Ceiling Diffuser – 250 to 160 mm

The Econox acoustically insulated plenum is specially designed for uniform air distribution and effective sound attenuation behind an Econox ceiling diffuser. The plenum captures air from the duct and distributes it evenly across the ceiling diffuser, allowing air to enter the room quietly and without drafts. At the same time, the internal insulation reduces airflow noise, ensuring a quieter installation. With a connection diameter of 200 mm, the plenum seamlessly attaches to the ceiling diffuser of the same diameter. Thanks to the 200 to 160 mm transition, you can easily connect the plenum to a smaller air duct without additional adapters.

Benefits and Features

• Acoustic insulation: Reduces airflow noise and prevents transmission into the room, ensuring a quieter system.
• Integrated air distribution plate: Distributes air evenly across the diffuser for comfortable indoor climate.
• Adjustable damper with measurement function: Allows precise adjustment and monitoring of airflow.
• Compact build height: Suitable for installation in suspended ceilings where installation space is limited.
• 200 to 160 mm transition: Direct connection to ductwork with smaller diameter without extra adapters.

Installation and Maintenance

The plenum is mounted directly onto a 160 mm round duct, with the diffuser connected on the 200 mm side. The compact design facilitates easy installation in modular ceilings. The removable control damper provides good access to the duct and plenum during maintenance or cleaning. This reduces service time and simplifies periodic maintenance. With this plenum, you achieve a quiet, easily adjustable air supply that integrates seamlessly with ceiling diffusers and modern ventilation systems.
