Polyflow Capsules feature a random-fiber polypropylene depth matrix that provides superior retention efficiencies in excess of 99%. In addition, PTI’s unique calendering process produces depth media with unsurpassed dirt-holding capacity that extends the service life. Longer life leads to increased savings by requiring fewer filter change-outs.

Polyflow capsules are available in a choice of three sizes, allowing users to match the filters to the batch size and minimize the hold-up volume. Cost savings result from the reduction of lost product, and by scaling the process properly to avoid wasting excess filter capacity.

The encapsulated design maximizes efficiency by providing faster, easier change-out with no laborious cleaning procedures. Eliminating the replacement of filter elements minimizes the chance of introducing contamination into the process. And eliminating the need to open pressurized housings for cartridge removal increases the level of safety by reducing the risk of exposure to potentially hazardous fluids.
