UniBag filter bags are designed for use with bag filter housings. UniBag filter bags are considered to be a slight improvement over Snap-Ring filter bags and as such are also considered an "economy" choice for basic filtering applications to a nominal 65% to 70% level of efficiency. As the filter bag model/design improves, the material it is made from become thicker and the sealing method becomes more efficient. As with the Snap-Ring filter bags, UniBag filter bags are made with a sewn construction, although unlike Snap-Ring filter bags, UniBag filter bags are made from recycled fibers.

What makes the UniBag filter bags an improvement over Snap-Ring style filter bags is the sealing method. UniBag filter bags have a crush seal design per the higher quality Sentinel, DURAGAF, LOFCLEAR, ACCUGAF and PROGAF filter bags. Unlike the snap-ring closure, the Sentinel style crush ring seal has larger contact area against the restrainer (support) basket. Downwards pressure from a separate sealing ring or from the bag filter lid (goose neck style bag filters) creates a bypass free seal and is therefore recommended for all applications, especially when the desired retention is

PROGAF filter bags are the epitome of high efficiency filter bag design, it sets the standards for all other in terms of particle loading and retention efficiencies. PROGAF filter bags are often used to replace specialized filter cartridges due to higher flow rate requirements or simply to reduce operating costs.

Akin to the ACCUGAF filter bags, PROGAF filter bags also have a multiple layer construction; they have more layers and a special, patented sealing ring referred to as a STEP-RING, whose sealing against the restrainer (support) basket actually improves with increased differential pressure!

PROGAF filter bags are used for critical filtration applications, often related to pharmaceutical, biotech, fine chemical and potable water/beverage applications.

Sentinel filter bags are the industry standard "every day" filter bags for industrial applications. Unlike less expensive Snap-Ring and UniBag filter bags are made from a heavier material and are all made from a fully welded construction. The heavier material provides slightly more depth filtration, essentially a torturous path for the fluid and particles to navigate; the particles are retained and the liquid passes through.

The fully welded design increases the strength of the filter bag. The restrainer (support) basket relieves most of the weight stress from the filter bag, however the differential pressure stress will usually cause sewn seams to burst before welded seems would.

Sentinel filter bags are made in the widest number of materials and retentions and their universal #1 through #4 sizes will fit any brand of bag filter designed for #1 through #4 sizes. Sentinel filter bags also provide nominal retention efficiencies of 65% to 70%.

LOFCLEAR filter bags are a specialized, premium filter bag. LOFCLEAR filter bags are designed to have "absolute", 99% efficiencies. There are multiple styles available, some are pleated to increase the available surface area and others are made from a denser material with the specific intent of trapping gelatinous particles as well as traces of silicon oils which negatively effect coating applications (especially in the automotive industry).

LOFCLEAR filter bags are specialized and not typically applied to applications other than final coating applications. We've created a separate website called http://www.eatonfilterbags.com to provide all of the information you would ever want to know about any of the filter bags we offer.
