ABSTRACT:
A fluid handling device having a support frame and a plurality of filter frames attached thereto. Each of the filter frames has an outer frame member that removably secures a filter; the filters being either a planar filter, pocket filter, or multiple pocket filter. The various filters can be arranged to correlate the change-out schedule of all of the filters across the fluid flow area. The filters with the highest particulate capacity can be arranged to be in the zone of the fluid flow area with the highest particulate concentration. The filters are easily constructed from a single piece of filtration media and collapsible to save space when storing or shipping.
