UNIVERSAL ELBOW

Description

Universal Elbow is a ducting connector fitting that creates a clean 90-degree bend in grow room and extraction ductwork, allowing ventilation systems to navigate corners, change direction, and avoid obstructions without restricting airflow or compromising the integrity of the duct run. We have been recommending quality ducting fittings to UK growers since 2017 as an essential component of a well-designed, efficient ventilation installation — the difference between a system with properly fitted elbow connectors and one using sharply bent flexible duct can be significant in terms of airflow efficiency and system noise.

Why Proper Elbow Connectors Matter for Extraction Efficiency

Airflow through ducting is highly sensitive to the geometry of bends and turns. Flexible duct that is sharply folded or kinked at a 90-degree angle creates significant turbulence and flow restriction — the cross-sectional area of the duct at the bend is effectively reduced, and the turbulent airflow generates noise and reduces the effective output of the fan by increasing back pressure. A purpose-made elbow fitting maintains full duct diameter through the bend with a smooth, gradual curved internal profile that guides air through the change of direction with minimal turbulence and pressure drop. This means your fan operates closer to its rated free-air flow point, extracting the volume of air it is rated for and reducing the noise generated by turbulence in the duct system. The Universal Elbow is designed to accept standard flexible or rigid ducting at both ends, making it compatible with all common UK grow room duct sizes when paired with the appropriate diameter unit.

How to Install the Universal Elbow in Your Duct System

Insert your ducting into each end of the elbow fitting, pushing firmly to seat it correctly. Secure each connection with a METU clamp or jubilee clip for an airtight, pull-resistant join. Position the elbow to achieve the required direction change and support the fitting at its midpoint to prevent mechanical stress on the duct connections. Seal all connection points with duct tape if required for odour containment applications. Check for air leaks by feeling for airflow around the connection points with the system running and reseal any gaps.
