Lowell FW-FF Fan Filter, 4.7-Inch
The FW-FF is the replacement filter for Lowell's whisper fans, sized at 4.7 inches in diameter. A rack fan pulling dust straight through the equipment underneath it is how thermal problems start, and this is the part that gets swapped rather than the fan.
It is a maintenance and spares item, not a fan. Lowell publishes the diameter and the compatibility and nothing further for this part; call if you need anything beyond that confirmed before ordering.
