Acoustically insulated plenum for ceiling diffuser - 200 to 125 mm

Acoustically insulated plenum for ceiling diffuser – 200 to 125 mm

The Econox acoustically insulated plenum is specifically designed for even air distribution and effective sound attenuation behind an Econox ceiling diffuser. The plenum collects air from the duct and distributes it evenly across the diffuser, allowing the air to enter the room smoothly and draught-free. At the same time, the internal insulation dampens the noise of the airflow, resulting in a quieter installation. With a connection diameter of 200 mm, the plenum connects seamlessly to the ceiling diffuser of the same diameter. Thanks to the transition from 200 to 125 mm, the plenum can easily be connected to a smaller duct without additional fittings.

Advantages and features

• Acoustic insulation: Reduces air noise and prevents sound transmission into the room, ensuring a quieter installation.
• Integrated air distribution plate: Evenly distributes the air over the diffuser for a comfortable indoor climate.
• Adjustable damper with measuring function: Allows precise adjustment and monitoring of the airflow rate.
• Compact installation height: Suitable for installation in suspended ceilings with limited space.
• 200 to 125 mm transition: Direct connection to ductwork with a smaller diameter without extra adapters.

Installation and maintenance

The plenum is mounted directly onto a 125 mm round duct and the diffuser is connected on the 200 mm side. The compact design allows 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 makes regular maintenance straightforward. With this plenum, you achieve a quiet, well-adjustable air supply that connects seamlessly to ceiling diffusers and modern ventilation systems.
