PROGAF™ FILTER BAGS

Ultra High Efficiency Filter Bags

 
PROGAF Specification Sheet

PROGAF filter bags provide BETA 5000 retention efficiencies with a high performance, multilayer design that rivals the performance of filter cartridges.  PROGAF filter bags are manufactured from melt-blown polypropylene and have a special layered "step" crush seal style filter bag to eliminate particle bypass in support of 1 micron particle retention with 99.9%.  This equates to a  BETA 5000 ratio or retention of 4999 of 5000 one micron sized test particles during laboratory testing.  The ultra pure polypropylene filaments used in the construction of PROGAF filter bags are silicon free and subject to rigorous ISO 9001:2015 quality control procedures to ensure performance.  PROGAF filter bags are hydrophobic and are in compliance with the FDA requirements according to title 21, Section 177 and the EC Directives 1935/2004 and 2002/72/EC for contact with food and beverages.  All layers of PROGAF filter bags terminate to a common welded seam.

 

The sealing ring is referred to as a STEP-RING and its multiple step design corresponds with the multiple layer design of PROGAF filter bags, which have as many as 12 layers.  The seal of a crush seal design filter bag improves with an increase in differential pressure.  The filter bag seal is made from polypropylene and each filter bag layer is welded to the sealing ring.  The integrally molded handles simplify removal from the filter housing.

 

 

 

The combination of several filtration layers optimizes the particle retention holding capacity by distributing the coarser particles within the outer layers and finest particles within the inner layers.  The progressively finer structure of PROGAF filter bags is akin to using several bag filter housings in series and thus reduces the number of bag filter housings and filter bags and the associated downtime corresponding to filter bag changes.  The outermost layer consists of polypropylene mesh to prevent fiber migration.

 

Specifications:

 

There are (3) PROGAF filter bags made in the universal #2 size (7" diameter x 32" long) having BETA 5000 (99.9%) efficiencies of 1, 2 and 12 microns.
