Felt filter bag materials are made from synthetic fibers in polypropylene or polyester. The proper combination of fiber diameters, weights and thickness results in an economical depth type filter media. Polypropylene & polyester bags are supplied witih a glazed finish to reduce fiber migration.

PRESSURE DROP DATA

The graph shows the DP produced by a #2 size bag for water, 1 cps @ 68° F. The pressure drop is specific to the type of bag, the micron rating and flow rate for the filter bag only. It does not include the pressure drop caused by the housing & basket.

Bag Size and Viscosity Correction

For other than #2 size bags, multiply DP from above table by the bag size correction factor below to calculate DP. If viscosity of the liquid is greater than 1 cps (water @ 68° F), multiply the result by the proper viscosity correction factor.
