3 1/2'' Plastic Fan Filter Assembly
By Qualtek Electronics (90F1254)
Assemblies consist of guard, polyurethane foam filter media and media retainer for tube-axial fans. Easy to install, secure the guard portion with mounting screws, (not included) then snap-on the retainer and filter media with no extra hardware or brackets. When the filter requires maintenance, the guard and fan do not need to be removed. Just remove retainer and clean or replace the media.
