The Filter Bag That Works Better Than a Filter Cartridge

PROGAF filter bags bring a new, high-performance alternative to applications requiring absolute filtration.  Their progressive density depth filtration delivers high efficiency (up to 99.9%) and long life like a filter cartridge with all the convenient features of a bag filter.  In comparison with other filtration technologies, PROGAF delivers lower operating costs while retaining the ease of change-out typical of a bag filer.



Progressive Density Media Structure

PROGAF filter bags utilize an advanced media structure developed specifically to deliver both long life and absolute filtration.  Their progressive density design uses up to 12 layers of media which become finer and finer as fluid passes through. The result is a gradual removal of contaminant without any single layer blinding prematurely. Application and laboratory tests confirm that PROGAF filter bags deliver longer service life and lower operating cost than any other renewable filter element.  The 100% polypropylene construction provides pure, silicone-free materials in an economic, self-contained, easily disposable filter bag.

See the Difference...Compare PROGAF to Filter Cartridges

The two charts below graphically illustrate the advantages of PROGAF high-performance filter bags over different types of filter cartridges.  PROGAF filter bags and filter cartridges come in many shapes and sizes.  Compare PROGAF filter bags with their cartridge equivalent in material, micron rating and industry qualifications.  The progressive structure of PROGAF filter bags delivers higher dirt holding capabilities and lower operating differential pressures than other comparable filters.  These charts illustrate the results of actual comparison tests made against two common styles of cartridge filters:  depth-loading and pleated polypropylene and a competitive high-performance filter bag.

Filtration Efficiencies of up to 99.9%

PROGAF filter bags have performance efficiencies of up to 99.9%...true absolute filtration.  In many filtration applications of 1 micron and above, PROGAF filter bags can replace expensive cartridge filtration systems and provide better performance while saving time and money.  Ask your Eaton Filtration Specialist for "real world" documented case histories, illustrating how PROGAF filter bags have performed in application similar to yours.

Retention Efficiency, PROGAF Filter Bags

Choose the Precise Efficiency Needed.

PROGAF™  filter bags are identified using efficiency codes: 50, 51, and 55. First, using the chart on the left, choose the retention efficiency level you need at a particular micron retention. Next, find which bag (identified by the colored lines) is closest to that point.
