Round 90° PVC Elbow Connector airRoxy 100 mm

Round 90° PVC Elbow Connector airRoxy 100 mm is a right-angle duct fitting designed for ventilation and air extraction systems. The connector provides a compact 90-degree change of airflow direction for circular ducts with a 100 mm diameter. Made from PVC, the fitting offers corrosion resistance and a smooth inner surface to maintain airflow efficiency while remaining lightweight for straightforward handling and installation.

Advantages

The PVC construction ensures durability against moisture and many common atmospheric contaminants, reducing the need for frequent replacement. Its smooth internal profile minimizes airflow resistance and turbulence at the bend, helping to preserve fan performance and reduce noise. The round shape and standardized 100 mm diameter allow compatibility with common rigid and flexible circular ducting, and the component's low weight simplifies mounting and alignment during installation.

Suitable for

• Residential and commercial HVAC systems requiring a compact 90° turn
• Kitchen and bathroom air extraction ducts
• General ventilation routes in utility rooms, garages, and workshops
• Connections between rigid ducts and flexible hoses where a right-angle change is needed

Key specifications

• Shape: Round 90° elbow
• Material: PVC (polyvinyl chloride)
• Nominal diameter: 100 mm
• Function: Change of airflow direction by 90 degrees
• Surface: Smooth inner profile to reduce airflow resistance
• Weight: Lightweight for easy handling (typical of PVC fittings)

How to use

Measure and prepare duct ends to ensure clean, square cuts that match the connector diameter. Insert the connector into or over the duct ends according to whether the system uses spigots or slip-fit joints, and secure with appropriate clamps, screws, or duct adhesive compatible with PVC. Ensure joints are aligned to avoid kinks in flexible ducting and check that the bend orientation directs airflow as intended. After installation, inspect seals and fastening points to prevent air leaks and confirm unobstructed airflow through the elbow.

Usage recommendations

For optimal performance, avoid tight successive bends immediately before or after the 90° elbow and maintain gradual transitions where possible. Use clamps or PVC-compatible adhesive rated for ventilation applications to ensure airtight joints. When connecting flexible ducts, support the duct to prevent sagging at the elbow and periodically inspect the fitting for deposits or wear in dusty or greasy environments.
