Frequently asked questions

The PPDP combines pleated filtration with increased pleat pack depth, giving it depth-filtration characteristics on top of the usual pleated surface-area benefit — this graded structure captures larger particles on the outer surface while finer particles are retained deeper within the media, giving it more capacity for softer, gelatinous contaminants than a standard PPP.

The PPDP range covers particle removal from roughly 1 to 40 microns, giving it a broad span from coarse pre-filtration through to finer polishing duties within the same product family.

It's developed specifically with brewery and spirits/liquor production in mind, alongside general pre-filtration ahead of absolute membrane stages and industrial swarf (metal particulate) removal — its depth structure suits softer, gelatinous contaminants common in beverage processing better than a standard pleated cartridge.

Yes — it's manufactured from WRAS-approved materials with individual lot coding for full traceability, alongside its beverage and industrial applications.

It uses melt-blown filter media on a polypropylene core with thermally welded end caps, so there are no adhesives that could leach into the filtered liquid — important for beverage and other sensitive applications.
