This Omega National straight liner is the metal T-shaped insert that fits inside a compatible wood range hood shell and houses the ventilation equipment for the Sirius SUT90870M. It bridges the decorative wood enclosure and the ventilator, giving the installation a clean, finished interior while seating the blower unit correctly.
A wood range hood works as a system: the decorative shell handles the visual work, and the liner and ventilator handle the functional work. This liner is the mechanical interface between the two. Its T-shaped profile establishes the correct geometry for the SUT90870M to mount cleanly, and the precisely cut hole at 9-7/16 by 10-3/16 inches aligns with the blower throat so airflow is not interrupted by a misfit between parts. Getting this component right at the specification stage prevents rework once the hood shell is installed and the ventilator is ready to drop in.
The interior of a range hood liner takes the same exposure as any other surface above a cooktop: heat, moisture, and airborne grease. The Silver Metallic finish on this liner holds up to that environment while keeping the interior looking intentional rather than utilitarian. It pairs naturally with the polished or brushed metal components common in professional-style kitchens and does not compete visually with the wood shell surrounding it.
This liner is the right call when a project uses the Omega National Sirius SUT90870M ventilator and a wood hood shell sized for a 48-inch liner. Kitchen designers and cabinet installers working on custom or semi-custom hoods reach for it when the hood shell is already in place and the ventilator selection is confirmed. It is also the correct replacement part when an existing Sirius installation needs the liner swapped out. The fit is model-specific, so the ventilator and the liner are confirmed together before the shell goes up.
No. This is the liner only. The SUT90870M ventilator that moves the air is a separate product and is ordered on its own.
This liner is matched specifically to the SUT90870M. Confirm the ventilator model number before ordering, since other Sirius models may use a different liner configuration.
No. This is the metal liner that installs inside a wood hood shell. The decorative wood shell is a separate product chosen for the style and species of the kitchen.
The 48-inch designation is the nominal liner class. The actual measured width is 46-7/16 inches, which is the working dimension to use when checking fit against the hood shell opening.
Specifying this liner correctly alongside the SUT90870M ventilator means the hood shell, liner, and blower go together without adjustment, and the finished hood reads as a single, cohesive unit above the cooktop.
