The Trane FLR7963 is the OEM replacement air filter specifically engineered for the PerfectFit enclosure

Optimized Airflow: Precision wire spacing maintains HVAC system efficiency by allowing maximum discharge velocity without compromising safety

preventing arcing at the start relay and ensuring consistent performance during short-cycling

allowing a 3/4-inch sweat connection without re-piping the entire manifold

Using this coil with a DC power supply will result in insufficient holding force or potential damage to the winding
