8-Outlet Galvanized Plenum Box with Rectangular Connection for Ventilation Systems

The plenum box with a rectangular connection is designed for uniform airflow distribution in supply and exhaust ventilation systems. This HVAC distribution box provides a convenient transition from a flat (rectangular) main air duct to a network of round 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 form factor with a rectangular inlet is specifically designed to save installation height in confined suspended ceiling voids.

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: Made via a rectangular flange (for flat ducts with a height of 50 mm or 90 mm), which minimizes the overall height of the ventilation system.
• Duct connection: The round 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: 4 round spigots are located on one long side of the casing, and 2 spigots are located on each of the short side panels. The rectangular inlet is located on the opposite long side.
