PROGAF, The Filter Bag that Works Better Than a Filter Cartridge
PROGAF filter bags utilize an advanced media structure developed specifically to deliver both long life and absolute filtration. PROGAF filter bags’ 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 bag filters deliver longer service life and lower operating costs than any other renewable filter element. The 100% polypropylene construction provides pure, silicone free materials in an economic, self contained, easily disposable filter bag. Filtration Efficiencies of Up to 99.9% PROGAF High Performance Filter Bags have performance efficiencies of up to 99.9%…true absolute filtration. In many filtration applications of one micron and above, PROGAF Filter Bags can replace expensive cartridge filtration systems and provide better performance while saving time and money. The PROGAF™Filter Bag Difference Ordinary standard filter bags are made from needled felt media that has a fiber structure not as fine and precise as the filtration grade melt blown media used for PROGAF Filter Bags. The needled fibers are much larger in size and spaced much further apart, yielding a lower efficiency. PROGAF Filter Bags have been designed to deliver calibrated fractional efficiency on very small particles, down to less than one micron. The bags feature a completely welded construction and the unique, patented SENTINEL® Sealing Ring for a positive by-pass free seal. And all PROGAF Filter Bags have a round bottom shape for increased pressure stability. Choose Just the Filtration Efficiency Your Application Needs PROGAF Filter Bags are available in efficiency codes of 50, 51, and 55. To select the perfect PROGAF Filter Bag for your application, choose the micron retention efficiency level you need on the left side of the chart at particle size in microns at the bottom. Next, locate the bag efficiency code (identified by the colored lines) that is closest to that point.
Some Typical PROGAF™Applications All materials used in the construction of PROGAF Filter Bags, including the multi layer melt-blown polypropylene media, are FDA/EC listed materials that meet their requirements for food contact applications. But food or beverages are not the only applications that can take advantage of PROGAF’s high filtration efficiencies and capacity retention. The pharmaceutical, micro-electronics, chemical, food, ink and paint, and water treatment industries can also use PROGAF High Performance Filter Bags. Chemical and Pharmaceutical Industries Demanding filtration in high purity industries are the applications PROGAF was made for. Media capable of removal to 2 µm absolute with long service live is essential for activated carbon removal or catalyst recovery. Gel removal requires a deep matrix of fine fibers. A PROGAF bag is ideally suited for each of these applications. Available in four filtration ratings, one of the PROGAF bags will deliver just the needed performance. Water Filtration Water filtration applications have traditionally been dominated by cartridge filtration. Following extensive worldwide trials, PROGAF 51 has demonstrated a log 3.5 reduction of impurities in these demanding applications. Micro-Electronics These applications typically require chemicals that are constantly filtered to extremely low levels of particle contaminant. PROGAF’s special profile, with its high efficiency media and graded density structure, provides performance characteristics superior to that of traditional cartridge type filtration. PROGAF out performs cartridges in terms of dirt holding capacity, service life, and cost. Membrane prefiltration significantly reduces the SDI values in water filtration. Compare PROGAF™to Filter Cartridges and See the Difference The two charts on the next page 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. Progressive structure of PROGAF filter bags delivers operating differential pressure which starts and remains lower during filter life than other comparable filters. The chart shown here illustrates the results of actual comparison tests made against two common styles of cartridge filters: depth loading and pleated polypropylene. During laboratory loading tests, the PROGAF filters remained at the lowest differential pressure of any of the three over the life, illustrating the effectiveness of the progressively structured media.
