Interior Ductwork Kit for Broan 260 starts as a dedicated interior ducting solution designed for Broan ventilators, so installers get a defined path for routing range hood exhaust back into the kitchen when exterior ducting is not used. The kit is described as an interior duct kit for ducting range hood exhaust back into the kitchen, which directs air away from the cooking surface while still keeping it within the room. It is complete with a charcoal filter, so the exhausted air passes through a filtering media before it reenters the space. The product is identified as Omega National Products Manufacturer Part 90360DUC1, giving installers a precise part number to match to drawings and ordering systems. It is positioned under range hood accessories and ductwork kits, which helps place it correctly within a kitchen ventilation plan.
The interior duct kit for ducting range hood exhaust back into the kitchen is designed to sit in the exhaust path of a Broan ventilator, giving a defined location where air transitions from the hood to the interior duct route. Because it returns exhaust back into the kitchen, layout planning can focus on internal cabinet or chase routes without planning an exterior termination. The kit is complete with a charcoal filter, so the exhaust stream is conditioned before it enters the room path. As a ductwork kit in the range hood accessories category, it is intended to integrate into the overall hood and ventilator assembly during installation.
This interior duct kit is designed for ducting range hood exhaust back into the kitchen, so it suits projects where routing to an exterior wall or roof is not part of the plan. It is specifically described as designed for Broan ventilators NPRHVBF300SS, NPRHVB400SS, and NPRHVB600SSV, which anchors its use to those named models in the 260, 400, and 600 CFM ventilator range. By matching the stated ventilator models, installers align duct routing with the intended airflow capacity of those units. The Omega National Products branding and Manufacturer Part 90360DUC1 give a consistent reference for specifications, project documentation, and future reorders across multiple kitchens or phases.
The description as an interior ductwork kit signals that the components are organized around routing exhaust air inside the building rather than through an exterior penetration, which supports repeatable planning for similar kitchen layouts. Because it is complete with a charcoal filter, the exhaust air passes through a defined filtration stage every time the ventilator runs, creating a predictable conditioning step between the hood and the room. The classification under range hood accessories and ductwork kits keeps this product aligned with the ventilation side of a cabinet package, so designers and installers can reference it alongside the selected Broan ventilators. Using the Manufacturer Part 90360DUC1 across orders ties field installation back to the same specified interior duct approach on future jobs.
