Round Duct Termination with Mesh

A round galvanized steel duct termination with a protective mesh is used to finish supply and extract ventilation lines at their exterior or terminal points. This component provides an essential physical barrier that prevents birds, rodents, large leaves, and outdoor debris from entering the ductwork, keeping the entire ventilation network clean during operation or seasonal downtime. The precise geometric design minimizes localized airflow resistance at the intake or exhaust point, helping to maintain the system's calculated volumetric performance while reducing air turbulence noise.

This component is manufactured from durable galvanized sheet steel, engineered for long-term resistance to atmospheric moisture and outdoor exposure. Automated factory production ensures an exact collar profile, simplifying component alignment during on-site assembly and eliminating pressure losses or air leakage at the end of the line.

Key Benefits of the Round Mesh End Cap

• Reliable barrier protection without airflow restriction: The integrated metal wire mesh features a standardized 13x13 mm grid that effectively blocks pests and external objects without causing significant static pressure drops.
• Dual-contour airtight installation: Equipped with a built-in double-lipped EPDM rubber gasket, the component seals tightly against the inner walls of the duct, preventing air bypass and eliminating the need for sealing tapes.
• Safe handling and increased radial stiffness: The collar edges are rolled using machine-turned SAFE technology (up to  D-400), which removes sharp burrs to protect installers from cuts and reinforces the shape against physical deformation during assembly.
• Simple mechanical fixing: The calibrated male connection profile slides directly inside standard straight round ducts, allowing quick alignment and secure fastening with standard rivets or self-tapping screws.
