Product: Round Duct Reducer (100mm to 150mm) Description: Material Construction:This round duct reducer is made from high-quality ABS materials, ensuring corrosion resistance, high hardness, and durability. The one-piece molding process creates a leak-proof and explosion-proof reducer that is designed for long-lasting performance. Functionality:The reducer is ideal for connecting different diameter vent pipes, providing a smooth transition from 100mm to 150mm. It is perfect for use with clothes airers, bathroom fans, extractor fans in kitchens, hydroponics systems, and more. Sealing Installation:The reducer features a smooth surface for easy installation on various types of vent pipes. It can be used with both rigid and flexible duct systems. For rigid systems, seal with putty or tape, and for flexible systems, use a hose clip to secure the connection. Versatility:This duct reducer is suitable for a wide range of applications, including whole house ventilation, passive chimney venting, positive inlet systems, air conditioning, and heat recovery systems.Details: Corrosion Resistance Deformability:Made of new ABS material, the reducer is resistant to corrosion and maintains its shape over time. Wind Resistance:The reducers reasonable over-design and smooth interior reduce wind resistance rates, ensuring efficient airflow. Seamless Universal:The seamless structure provides a good sealing effect and is suitable for both indoor and outdoor use.Installation Diagram: Attach the 100mm pipe to the smaller end of the duct reducer and the 150mm pipe to the larger end. Secure the interface with aluminum tape to ensure a tight seal. Place a hose clamp over the connection and tighten it with a screwdriver to ensure the reducer stays in place.Note: Always ensure proper installation to maintain the integrity and efficiency of your ventilation system.
