Rectangular PVC Duct Adapter T-piece airRoxy 110/55 for ventilation ducts

The Rectangular PVC Duct Adapter T-piece airRoxy 110/55 is a PVC ventilation fitting designed to create a rectangular branch from a main duct. It provides a transition between a 110 mm main run and a 55 mm rectangular branch, enabling airflow splitting or reduction within residential and commercial ventilation and extractor systems. The adapter is intended for use where a compact, rigid junction is required to route or redirect conditioned air or exhaust.

Advantages

This PVC T-piece offers durable, corrosion-resistant construction that is lightweight and simple to install. Its rectangular branch design allows efficient connection to smaller rectangular ductwork or fittings, reducing the need for complex transitions. The smooth internal surfaces support steady airflow with reduced turbulence, and the rigid material maintains its shape under typical ventilation pressures.

Suitable for

• Splitting a main ventilation run to feed a smaller rectangular branch
• Connecting extractor hoods or localized exhaust points to a larger duct
• Residential and light commercial ventilation systems
• Retrofit projects where size reduction and a compact junction are required

Key specifications

• Material: PVC (rigid polyvinyl chloride)
• Main connection diameter: 110 mm round-equivalent main run
• Branch connection size: 55 mm rectangular branch
• Type: T-piece / branch adapter for ductwork
• Application: air supply and exhaust in ventilation systems

How to use

Install the airRoxy rectangular T-piece by fitting the 110 mm main duct to the primary inlet and securing the 55 mm rectangular branch to the targeted duct or fitting. Ensure connections are aligned and sealed using appropriate duct sealant, tape, or clamps compatible with PVC to prevent air leakage. Verify that the adapter orientation directs airflow as required and that surrounding supports hold the ducts in place to avoid strain on the joints.

Usage recommendations

Before final installation, check compatibility with existing duct profiles and measure the rectangular branch opening to confirm a correct fit. Use PVC-compatible adhesives or approved sealing materials for permanent joins and maintain regular inspections to ensure seals remain intact and free from obstructions.
