ABS Air Distribution Box | Fresh Air ABS Plenum Manifold Box

ABS Air Distribution Box — Fresh Air Plenum Manifold for Ceiling and Concealed Systems

An ABS plenum box that takes one main duct from the MVHR unit and distributes it into multiple branch ducts. The moulded ABS body is lightweight, corrosion-free and dimensionally stable, and the internal volume smooths out turbulence so each branch gets more even airflow. It is the standard distribution component in concealed residential fresh air systems.

Key Features

• Multi-branch distribution — one inlet feeding several terminal branches
• ABS moulded body — light, strong, corrosion-free, no rust staining on ceilings
• Even airflow — the internal volume damps turbulence for better branch balance
• Concealed installation — compact footprint fits ceiling voids
• Multiple port options — configured to match 75 mm and 110 mm duct systems
