Description
The Trane FLR6466 is a precision-sized pre-filter engineered to work as the first line of defense in your HVAC air filtration system. Measuring 24.19″ L x 26.07″ W, this OEM pre-filter is designed to capture larger airborne particles — including dust, lint, and debris — before they reach your primary filter media or sensitive system components.
By intercepting coarse contaminants early in the airstream, the FLR6466 helps extend the service life of downstream filters, reduces maintenance frequency, and protects heat exchangers, coils, and blower assemblies from fouling. It is an ideal replacement for Trane air handling units and commercial HVAC systems that require a pre-filtration stage.
