Replacement grill for Broan 509S

This Broan-NuTone grill is designed specifically for the 509S ventilation unit. It serves as a direct replacement component for residential exhaust systems. Homeowners maintaining existing ductwork will find the correct fit. The part number 97011790 ensures exact compatibility.

Consistent airflow coverage

The grill maintains steady air movement through the duct opening during continuous fan operation. Its fixed-louvre design does not rely on moving parts that can wear or stick over time. Air distribution remains uniform across the face of the register. This supports reliable ventilation performance day after day.

Passive thermal management

The component adds no electrical load and generates no operational noise of its own. Constructed from durable materials suited for HVAC environments, it withstands typical temperature and humidity cycles. The grill simply channels exhausted air without restricting flow. Normal use places no extra demand on the connected fan motor.

Questions about this item

Does the Broan grill produce any noise or heat during continuous daily use?

The grill is a passive cover with no motor or fan, so it adds no noise or heat when the ventilation system runs all day.

What existing Broan ventilation unit must I already own for this 97011790 grill to fit?

It is made for the Broan model 509S; the grill will not mount on any other unit.

Can I keep my older Broan housing from before 2019 and just swap in this grill?

Yes, if the housing is the exact 509S model the grill will fit; other housings will not accept it.
