Broan-NuTone SV63433 ERV Core Filter (Pair)

The Broan-NuTone SV63433 ERV Core Filter (Pair) is the factory service replacement for the energy recovery cores used in Broan-NuTone SRV ERV energy recovery ventilators. Each order contains two cores, and Broan-NuTone’s own service-parts listing shows overall dimensions of 12.25 in. wide × 18.25 in. deep × 4.4 in. tall. If the ventilator on your job was built by Broan-NuTone, this is the OEM core set to reach for when the original cores are worn, crushed, or fouled beyond cleaning.

The core is the part of an ERV that does the real work. Stale indoor air leaving the building and fresh outdoor air entering it pass through the core in separate airstreams that never mix, while the core transfers sensible heat and moisture from one to the other. In winter the incoming air arrives pre-warmed with humidity retained; in summer it arrives pre-cooled and partly dehumidified, which takes load off the heating and cooling equipment. A torn, collapsed, or clogged core raises static pressure, cuts airflow, and drags energy recovery efficiency down, so the ventilator keeps running but stops earning its keep.

Key Benefits

• OEM Service Core: Supplied as the Broan-NuTone service part under SV63433, so the fit and core construction match what the ventilator shipped with.
• Restores Energy Recovery: Brings back the heat and moisture transfer the ERV was designed for, and clears the airflow restriction a fouled core creates.
• Sold as a Pair: Both cores in one order, so you can replace the full core set in a single visit rather than mixing a new core with a worn one.
• Lower Load on the HVAC System: Properly working cores condition the incoming ventilation air, which keeps the furnace or air conditioner from carrying the full ventilation load.

Common Questions

• What exactly is SV63433? It is the Broan-NuTone SRV ERV core filter, sold as a pair, a service replacement for the energy recovery cores inside the ventilator.
• How do I know the cores need replacing? Reduced airflow, a visibly crushed, torn, or heavily soiled core, and poor humidity and temperature recovery at the supply grilles are the usual signs on an ERV that has been in service for a few seasons.
• How do I confirm it fits my ventilator? Check the Broan-NuTone model number on the unit’s data label and match it to the core called out for that model before ordering SV63433.
