8-Outlet Galvanized Plenum Box with Offset Side Connection for Ventilation Systems

The plenum box with an offset side connection is designed for uniform airflow distribution in supply and exhaust ventilation systems, including heat recovery systems. This HVAC distribution box provides a reliable transition from the main air duct to a network of flexible air ducts.

The casing is manufactured from galvanized steel, offering corrosion resistance and providing sufficient structural rigidity for standard installation and operating conditions. The flat form factor, with a height of only 85 mm, allows for space-saving concealed installation in suspended ceiling voids or wall niches, minimizing the loss of usable room volume.

The insulated version features a dedicated layer of synthetic rubber thermal insulation. This construction is designed for systems exposed to a risk of condensation, as it effectively prevents moisture accumulation on the casing surface and reduces heat loss during air transport.

Design features:

• Material: Galvanized sheet steel.
• Thermal insulation: Insulated versions (with the 'I' index) are equipped with a protective layer of synthetic rubber.
• Main connection: Located on the side panel and offset from the center. This asymmetrical design allows for left or right main duct approach during installation.
• Duct connection: The spigots feature locking grooves for secure attachment of the flexible ducts.
• Mounting: The casing is equipped with mounting brackets for attachment to load-bearing structures (ceilings or walls).
• Configuration: 8 spigots are arranged in a single line on one of the long sides of the casing.
