MAX-LOAD™ PLEATED FILTER BAG Maximum particle load retained for bag filter housings

MAX-LOAD™ pleated filter bags are manufactured from the same polypropylene or polyester needle felt material which DURAGAF filter bags are made from and they are formed into a pleated cylinder to maximize surface area. MAX-LOAD filter bags have the greatest amount of surface area of any filter bag and they are used for minimizing the frequency of filter bag replacements. Reduced the frequency of change-outs also reduces labor costs, exposure to liquid and the quantity of filter bags to be inventoried and disposed. MAX-LOAD pleated filter bags are manufactured from silicon-free fibers under ISO 9001:2015 quality control standards to ensure consistent performance.

MAX-LOAD Filter Bag Design
The standard MAX-LOAD filter bag has an internal core made of the same material as the DURAGAF filter bag (polypropylene or polyester) which undergoes a treatment process virtually eliminating potential of fiber migration while remaining free from silicone and other crater-forming substances.

All seams and connections to the sealing ring are thermo bonded (welded) to maximize the durability of the MAX-LOAD filter bag. The internal core provides support akin to a filter bag positioner, protecting the filter bag form downstream pressure pulses often related to higher system pressures. MAX-LOAD pleated filter bags utilize a flexible crush ring seal to form both a chemically resistant and bypass-free seal which improves as the differential pressure increases. The sealing ring has integrally molded handles to simplify removal from the vessel. and due to a special surface. MAX-LOAD filter bags are provide for both #1 and #2 size filter bag vessels.

Coreless MAX-LOAD Filter Bag Design
The coreless version of MAX-LOAD filter bags have the look and feel of a filter cartridge however the flow path remains from inside-to-outside and thus particles are retained when removing the filter bag from the vessel. Unlike the other MAX-LOAD filter bags, the coreless version is made from polypropylene or polyester melt-blown materials; the same materials used for our absolute rated filter bags CLEARGAF, ACCUGAF and PROGAF. They are constructed of multiple layers, each graded for increasingly fine particle retention, resulting in a wall thickness of about 0.7″. They are available with a 10 micron nylon monofilament mesh cover for fiber sensitive applications.
