Filter Cartridges

Filter cartridges in 2.5" standard and 4.5" Big Blue formats, mostly in 10" and 20" lengths. The sediment range covers melt-blown cartridges from 0.5 to 100 µm, pleated cartridges from 0.2 to 50 µm, string-wound cartridges from 1 to 50 µm and absolute-rated pleated DOE cartridges at 0.2 and 1 µm. Most of the melt-blown range is made at DWT's Cape Town plant: 2.5" standard cartridges from 5" to 40" long and 4.5" Big Blue cartridges. The 62 mm standard range is published on datasheet DWT-DS-I-016 with nominal ratings and per-cartridge weights. Adsorption cartridges include carbon block, silver-nano carbon block, granular activated carbon (GAC), GAC/KDF and sediment/GAC combinations. Speciality items cover ceramic and carbon-core ceramic cartridges, a 100 µm nylon mesh cartridge, a Siliphos scale-prevention cartridge and double-length filter bags from 1 to 200 µm.

We're still adding our full range and more datasheets. If a part isn't listed, send us the code: we stock and source more than this catalogue shows.

How to choose

Match the cartridge to the housing first: diameter format (2.5" standard or 4.5" Big Blue) and length must both agree. Then choose the media for the job. Melt-blown, string-wound and pleated cartridges reduce suspended solids such as sand, silt and rust; they do not remove dissolved contaminants or microorganisms. Carbon block and GAC cartridges address chlorine, taste and odour. Sequence stages coarse to fine so the finer stage is not loaded with solids. Ratings are nominal unless the product states absolute; where a hard particle cut-off matters, specify an absolute-rated cartridge. For higher solids loads or larger flows, consider filter bags in a bag housing. Replace cartridges on rising differential pressure or at your service interval.

Lead times are indicative estimates only, based on typical supply at time of publication, and are confirmed at order acceptance. They show our usual longest sourcing time. We can often supply sooner from our network of local suppliers. Actual times may vary with supplier stock, manufacturing, importation, customs and logistics. Only a written quotation or order confirmation commits DWT to a delivery time.
