This concentric ducting reducer/enlarger allows ventilation components and ducting of different sizes to be connected within an extraction system. Manufactured from durable pressed steel, it provides a reliable solution for adapting between duct sizes when installing or modifying ventilation setups.
The concentric design enables the reducer to function in two ways depending on orientation. It can reduce duct diameter to connect larger ducting to smaller outlets, or enlarge the airflow path when connecting smaller ducting to larger ventilation components.
These reducers are commonly used in grow room ventilation systems, HVAC setups and ducting installations where equipment or duct sizes do not match.
Key Features
-
Concentric ducting reducer and enlarger adapter
-
Allows connection between different duct diameters
-
Made from lightweight pressed steel
-
Durable and suitable for repeated use
-
Compatible with flexible and rigid ventilation ducting
-
Suitable for grow room extraction systems and ventilation setups
How to Use
Insert the reducer between ducting or ventilation components of different sizes. The direction of installation determines whether the reducer decreases or increases duct diameter.
Connect flexible ducting using duct clips or duct tape. For rigid ducting connections, a female-to-female coupling may be required to secure the reducer between components.
