Housings for standard-format filter cartridges and filter bags. Slimline housings take 2.5" standard cartridges in 10" and 20" lengths, with 1/4", 1/2" or 3/4" ports and clear, blue or white sumps; double O-ring versions are available at 10". Big Blue housings take 4.5" cartridges in 10" and 20" lengths with 1" ports, in blue or clear. For larger duties the range includes a multi-element housing for five 30" melt-blown cartridges and a PVC bag filter housing for double-length bags. Empty refillable cartridges in both formats accept loose filter media. Wall and floor-standing brackets for single, double and triple installations, housing wrenches, replacement O-rings, mounting screws and a Big Blue pressure release button are stocked as spares.
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.
Start with the cartridge: 2.5" standard cartridges need a slimline housing, 4.5" Big Blue cartridges need a Big Blue housing, and the housing length must match the cartridge length. Choose the port size to suit the pipework and required flow; Big Blue housings with 1" ports suit whole-building and light industrial lines where slimline housings would restrict flow. A clear sump lets you see cartridge loading without opening the housing. For multi-stage trains, pick a matching double or triple bracket, noting that the slimline double and triple brackets fit the blue 1/2" and 3/4" housings only. Where flow or solids exceed what a single cartridge can carry, move to the multi-element or bag housing. Order a wrench and spare O-rings with every housing.

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.
