Ring Link Filter contains specialized media and filter designs which optimize particulate filtration airflow increase and maximize energy utilization in each application. FurnaceFilters.com MERV 7 HVAC & Paint 3-Ply 1 in. Ring Link Filters are ring panels that are formed in a continuous chain to eliminate bypass between panels. Like ring panels ring links are constructed from tow layers of 100% synthetic polyester media thermally sealed around a .148 inch galvanized wire. A support wire and radial bonds in the center of the panel keeping the media from sagging and fluttering to prevent dust migration. A one inch overlap of media around the support wire ensures a positive seal and no dust bypass. Each layer of media has multiple fiber deniers (fiber diameter) which graduate from coarse to fine for maximum dust loading and efficiency. A latex resin dry tackifier is added on the downstream side as an added dust migration prevention.
