Wall flange connector made from durable ABS Material and durability: Constructed from ABS plastic for longlasting, impactresistant performance. Built to maintain a secure connection under normal ventilation system use. Reliable connections: Designed to create a stable junction between duct sections and wall openings, reducing the chance of air leaks and loose fittings. Optimized airflow and performance Smooth interior profile reduces turbulence and resistance, allowing more efficient airflow between connected pipes. Improves overall ventilation efficiency by minimizing pressure loss and helping fans and vents operate closer to their intended performance. Compatibility and sizes Available in three sizes: 100 mm, 125 mm, and 150 mm to fit common duct diameters. Designed to match standard round duct piping sizes so you can select the correct flange for a snug, secure fit. Easy installation Simple wallmount design for straightforward installation. Mounting points allow quick attachment to walls or panels with common fasteners. Suitable for retrofit or installations; no special tools or complex fittings required. Key benefits — why you need it Prevents air leaks at wall transitions to improve system efficiency and reduce energy waste. Durable ABS construction gives stable, maintenance performance for residential or commercial ventilation. Smooth bore and proper sizing help maintain airflow capacity and reduce noise from turbulent flow. Typical applications Home ventilation: connect bathroom or kitchen exhaust fans to exterior wall vents for reliable moisture and odor removal. Commercial HVAC: use in smallscale duct runs in offices, retail spaces, or service areas to create durable wall transitions. Workshop or utility vents: install as an outlet for local exhaust or fume extraction where a compact, robust wall connection is required. What's included / how to choose Choose the flange diameter (100 mm, 125 mm, or 150 mm) that matches your ducting. Verify mounting surface and fastener type before installation to ensure a secure fit. Performance note Designed for standard ventilation duct use; ensure compatibility with your duct material and local building codes for results.
