PVC Over-Beam Fresh Air Duct Connector, Dual-Channel Beam Crossing Adapter for Residential Ventilation System

PVC Over-Beam Fresh Air Duct Connector — Beam Crossing Adapter

A PVC beam-crossing adapter for fresh air duct that has to pass a structural beam or downstand. Instead of dropping the ceiling, the connector routes the duct in a shallow profile around the obstruction and then returns it to the main duct size. The PVC body is rigid and the galvanised mounting clamps fix it securely to structure.

Key Features

• Crosses beams without dropping the ceiling — shallow-profile routing
• Rigid PVC duct body — holds shape and airflow area through the crossing
• Galvanised mounting clamps — secure, consistent fixing to structure
• Multiple duct sizes — 75 / 110 / 160 / 200 mm
• Simple assembly — designed for on-site installation

Technical Specifications

Typical Applications

• Fresh air ductwork crossing structural beams and downstands
• Concealed ceiling installations with limited void height
• Retrofit projects routing ducts through existing structures

System Matching

Works with HDPE corrugated pipe and flexible transition connectors. For a metal alternative see our custom pipe over-beam device.

FAQ

Q: Will it reduce airflow?
A: The connector maintains an airflow passage around the beam; the exact profile is sized to the duct and obstruction.

Q: How is it fixed?
A: Galvanised steel mounting clamps secure it to the structure.

Q: Which sizes are available?
A: 75, 110, 160 and 200 mm, as listed in the specification table.
