Durable stainless steel construction Made from robust stainless steel to withstand wear and tear and provide a reliable ventilation solution for heating and cooling installations. Effective size reduction Reduces pipe diameter from 120 mm to 50 mm, enabling compatibility with various heating and cooling applications with ease. Optimized airflow connections Facilitates proper connections between different diameters, helping maintain system performance and airflow efficiency. Easy installation for all users Designed for straightforward, hassle installation for both professionals and DIY enthusiasts. Key attributes Function: transitions between 120 mm and 50 mm ductwork to support varied system configurations Compatibility: suitable for heating and air conditioning ductwork requiring a 120 mm to 50 mm reduction Size: 120 mm to 50 mm reduction Material: stainless steel for durability and corrosion resistance Performance: supports secure connections and optimized airflow in venting applications Applications Retrofit an existing heating or cooling system by linking a 120 mm main duct to a 50 mm branch line or adapt venting connections in residential HVAC installations where smaller ductwork is required Install in commercial or residential settings to bridge larger exhaust piping to smaller diameter ducts while maintaining airflow efficiency Use scenarios 1) Upgrading a furnace vent where a 120 mm exhaust must connect to a 50 mm duct to fit equipment 2) Converting a large diameter vent in an air conditioning system to a smaller branch line without compromising airflow 3) Retrofitting a chimney or vent run in a retrofit project that requires a 120 mm to 50 mm step down while preserving system integrity
