WELDED CONSTRUCTION FOR SUPERIOR PERFORMANCE
All PROGAF™ high performance filter bags are characterized by 100% welded construction for improved
filtration performance. This construction ensures that nothing can pass through the stitching holes in the material caused by sewing. Patented welding technology makes a super strong weld that can withstand the most demanding applications.
PROGAF™ FILTRATION SEPARATIONS
PROGAF™ FILTER BAGS SEAL BETTER IN CRITICAL APPLICATIONS
The patented SENTINEL is a flexible, chemical-resistant seal that adapts to any filter kettle.
This unique design possesses a pressure-reactive sealing lip that responds to the increase in differential pressure. When the pressure
increases, the ring seal becomes even better and guarantees by-pass-free performance across the entire range of pressure, temperature and micron sizes. The integrated handles make changing fast and easy.
UNIQUE MEDIA WITH INCREASING DENSITY STRUCTURE
PROGAF™ filter bags have an advanced media structure, specially developed to deliver both long life and absolute filtration. PROGAF’s™ unique design of increasing density includes up to 12 layers of media that get finer and finer. The result is gradual removal of contamination without a single layer sealing too quickly. Usage and laboratory tests confirm that PROGAF™ bag filters deliver longer life and lower operating costs than any other replaceable filter element. The 100% polypropylene construction consists of pure, silicone-free materials in an affordable, easy-to-handle filter bag.
THE PROGAF™ DIFFERENCE
Ordinary standard filter bags are made of needle felt. These have a fiber structure that is not as fine and precise as that of melt-blown, from which PROGAF™ filter bags are made. Needlefelt fibers are much larger and farther apart, which means lower efficiency. PROGAF™ filter bags are designed to give precisely determined fractional efficiency on very small particles, down to even below one micron. The bag is characterized by a completely welded construction and the unique patented SENTINEL™ sealing ring. All PROGAF™ filter bags have a round bottom for increased pressure stability.
CHOOSE JUST THE FILTRATION EFFICIENCY YOUR APPLICATION NEEDS
PROGAF filter bags are available in efficiency codes of 50, 51, 55 and 57. To select the right PROGAF filter bag for your application, select the micron separation level on the vertical axis of the chart and the particle size in microns on the horizontal axis. Then find the pocket efficiency code (indicated by a colored line) closest to that point. Then you will have the most economical filter bag for your critical filtration application.
