High-Efficiency Filtration for Demanding Industrial Applications
When absolute filtration efficiency is critical to your process, standard needlefelt bags often fall short. The Eaton ACCUGAF™ filter bag series represents the upper echelon of bag filtration technology, delivering efficiencies greater than 99% for particle removal ranging from 1.5 to 25 microns.
At Purecowater, we supply high-performance filtration solutions like the ACCUGAF series to industries ranging from food and beverage to chemical processing. This guide outlines the specifications, benefits, and applications of these advanced filter bags.
What Makes ACCUGAF Filter Bags Different?
The ACCUGAF filter bag pushes the boundaries of traditional bag filtration. Unlike sewn bags which can allow bypass through needle holes, ACCUGAF bags utilize fully welded construction and Eaton’s patented SENTINEL® seal ring. This chemically resistant, pressure-activated ring ensures a 100% bypass-free seal against the filter housing, guaranteeing that “what goes in doesn’t come out” unless it passes through the media.
These bags are constructed from hydrophobic microfiber filter material (meltblown polypropylene or polyester), which requires pre-wetting but offers superior depth filtration characteristics compared to standard mesh or felt.
Key Features and Benefits
- High Efficiency: Greater than 99% particle removal efficiency throughout the service life.
- Graded Density: Meltblown media structure maximizes dirt-holding capacity.
- Recall Pure Purity: Polypropylene models are FDA compliant (CFR Title 21) and EC 1935/2004 compliant for food and beverage contact.
- Zero Bypass: All-welded construction and SENTINEL seal rings prevent fluid bypass.
- No Additives: Free from resins, binders, or surface treatments that could contaminate high-purity streams.
- Fiber Migration Control: A double downstream cover layer ensures virtually zero fiber release into the filtrate.

Primary Applications
Due to their high efficiency and pure construction, ACCUGAF bags are capable of handling sophisticated filtration tasks that standard bags cannot.
- Food & Beverage: Polishing filtration for beer, wine, and spirits; removal of particles from edible oils and soft drinks.
- Automotive & Metal Washing: Fine particle removal in parts cleaning and final filtration of lacquers/paints.
- Chemical & Pharma: Activated carbon removal, catalyst recovery, and filtration of high-purity process water.
- Industrial Systems: Filtration of hydraulic oils, lubricants, and vinegar processing.
Ordering Information
ACCUGAF bags typically come in box quantities (often 15 or 20 per box depending on the specific model). When upgrading your filtration system, ensure you verify the chemical compatibility of the seal ring and media with your process fluid.
