Zinc-plated steel ring EDR series

Product description
Galvanized steel sheet inlet duct rings designed for centrifugal and motorized-impeller fans to guide airflow into the impeller intake and optimize inlet performance in confined, high-static-pressure environments.

Overview
EDR series inlet duct rings fit a range of centrifugal/motorized-impeller fans. They help promote and stabilize airflow into the fan intake, enabling improved cooling capacity in applications such as electronic cabinets, HVAC components and other systems requiring high airflow in limited space. Available in multiple sizes to match common EA fan series.
