Ring Panel Air Filters

Ring panel filters offer some distinct advantages over conventional frame filters. They consist of multiple plies of polyester media secured to a 9 gauge metal frame. Excellent dust holding capacity. Rated MERV 8 at 374 fpm. The filter fits snugly into filter opening and does not allow air bypass. One inch filter is constructed of two layers - a 3/4 inch polyester with internal tackification and a 1/4 inch dense polyester. The two inch filter consists of a layer of 1 1/2 inch two ply polyester with internal tackification and a 1/4 inch dense polyester downstream. Withstands moderate amounts of moisture without losing strength. Standard size ring panel filters are sold in cases of 24. Non-standard size ring panels are sold in cases of 12. Ring panels can also be ordered as "link panels" which are several ring panels attached together. Link panels are useful for installing in side access filter housings. No air bypass between filters.
