Outer Diameter: 125 x 100 mm / 4.92 x 3.94 inch (Big*Small); Size: 120 x 0.6 mm / 4.7 x 0.02 inch (Height*Thickness)
Good Material: The duct reducer connector adapter is made of galvanized iron sheet, which is not easy to rust, is corrosion-resistant, durable, strong, and thick enough for the ducting system. The surface of the zinc coating is smooth and shiny, without burrs, ensuring a good ventilation effect.
Duct Reducer and Increaser: The vent reducer increaser is used as a duct adapter for reducing or increasing the diameters of an air duct, it's a useful duct fitting for changing your duct system to the needed size while maintaining smooth airflow.
Easy to Install: Connect the duct reducer to a metal duct, vent hose, fan outlet, or inlet, use a pipe clamp, glue, or tape to secure the connection if needed.
Application: The duct adapter has a wide range of applications, it is suitable for all kinds of ventilation systems, such as HVAC systems, bathroom and kitchen exhaust fans, chimney ventilation, air-cooled hood, embedded fans, range hood, dryers, hydroponic systems, dust collection equipment and so on.
Inner Diameter: 125 x 100 mm / 4.92 x 3.94 inch (Big*Small); Size: 120 x 0.6 mm / 4.7 x 0.02 inch (Height*Thickness) Good Material The galvanized iron sheet is not easy to rust, corrosion-resistant, durable, and does not require too much maintenance, saving time and money. The surface of the zinc coating is smooth and shiny, without burrs, and has good sealing performance. Made of hot-dip, suitable for all kinds of strong acid, and alkali fog environments. Duct Reducer By connecting two different sizes of pipeline openings to maintain airflow efficiency, when two different pipelines are connected to the ventilator, the solid pipes are used in the diameter or incremental pipe, and vice. Adapt to equipment such as bathroom fans and dust collectors. Easy to install Measure the different diameters of the pipeline, and then cut the pipeline into the different diameters into the required size. Insert the pipe connector into or on the pipeline, and then push them together. Application This is a very high-temperature resistant, sturdy, and integrated pipeline variable diameter increase pipe, which can be used to connect two different solid or flexible pipes or pipelines to a ventilator. Small. Suitable for the HVAC ventilation system, bathroom exhaust, air-cooled hood, embedded fans, hood, roller dryer, hydroponic system, kitchen or apartment, family garage attic or office space use together.
