Reducer adapter 150 mm to 100 mm — metal exhaust hose/duct connector designed for reliable diameter reduction in ventilation systems. Key benefits Ensures seamless connection between 150 mm and 100 mm ducts or hoses, maintaining efficient airflow and compatibility with existing accessories. Two-level (double-step) metal construction increases pressure resistance and provides a secure mechanical connection between pipes. Simple to install and suitable for both professional plumbers and home users; practical for all skill levels. Versatile use in residential and industrial ventilation systems; adapts to different installation environments and requirements. Features Size: reduces from 150 mm to 100 mm. Material: metal construction for durability and strength. Design: two-tier/stepped profile to reinforce the joint and improve hold under pressure. Function: for exhaust hoses, ductwork, and ventilation pipe modifications where a reliable diameter transition is needed. Performance Maintains airflow efficiency by providing a smooth transition between differing pipe diameters. Sturdy metal design resists deformation under typical duct pressures and handling during installation. Typical applications HVAC modification: connect a 150 mm inline fan or duct to a 100 mm branch line during system upgrades or repairs. Home appliance venting: adapt a dryer or range hood exhaust from 150 mm ducting to 100 mm flexible hose when space or existing fittings require a smaller connection. Industrial or workshop ventilation: reduce main duct diameter for spot extraction lines or tool-specific exhaust without fabricating custom fittings. Why choose this adapter Straightforward, dependable solution for matching different duct sizes without welding or complex parts. Suitable for a wide range of ventilation tasks, from routine home maintenance to professional installations. Metal, two-level construction provides a practical balance of durability and ease of use for long-term performance.
