The Filter Bag that Works Better Than a Filter Cartridge
PROGAF filter bags bring a new, high-performance alternative to applications requiring absolute filtration. PROGAF’s progressive density depth filtration delivers high efficiency (>99.98%) and long life 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 filter.
All PROGAF High Performance Filter Bags feature 100% welded construction for better filtration performance. This construction ensures that nothing bypasses the process media through holes in the fabric created from sewing the material. Eatons’s proprietary welding technology produces a super-strong seam that stands up to the most demanding applications.
The patented SENTINEL provides a flexible, chemicallyresistant seal which adapts to any filter vessel. This unique design employs a pressure-activated sealing lip which responds to increases in differential pressure. As the pressure increases, the seal of the ring improves, guaranteeing bypass-free performance over all ranges of pressure, temperature and micron rating. The elevated bag handles make removal quick and easy.
PROGAF filter bags utilize an advanced media structure developed specifically to deliver both long life and absolute filtration. PROGAF’s 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 materials3) in an economic, self-contained, easily disposable filter bag.
PROGAF High Performance Filter Bags from Eatons have performance efficiencies of over +99,98%….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 Eatons Filtration Specialist for “real world” documented case histories, illustrating how PROGAF Filter Bags have performed in applications similar to yours.
Ordinary standard filter bags are made from needled felt media that has a fiber structure that is 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. And all PROGAF Filter Bags have a round bottom shape for increased pressure stability.

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. There you have it: the most cost effective filter bag for your critical filtration application.
