Collection: Inox Sediment Filter Range

INOX cartridges are made from 316L stainless steel, a low-carbon, marine-grade steel with strong corrosion resistance. They're used where a disposable polypropylene cartridge isn't the right fit: hot water, chemical or process lines, or sites where you'd rather clean and refit a filter than keep buying new ones. As a pre-filter, they catch sand, scale, rust and other particles before these reach pumps, valves, membranes or UV systems.

All three are 316L stainless steel in the standard 2.5" diameter. The difference is filtration efficiency at the stated micron rating. EYS cartridges are rated at 80%, SPS at 90% and PPS at 95%. For example, a 40 micron PPS captures a higher proportion of 40 micron particles than a 40 micron EYS. EYS suits general coarse pre-filtration at a lower price. PPS is the better choice where tighter particle control matters, such as protecting membranes or process equipment downstream.

Choose the seal to suit the water or fluid running through the filter.
- EPDM is a good general choice for drinking water and hot water.
- Buna (nitrile) suits oils, fuels and hydrocarbons, but isn't recommended for hot water.
- Viton handles chemicals, solvents and higher temperatures.
- Teflon (PTFE) has the widest chemical resistance.
- Silicone is common in food and beverage use across a wide temperature range.

DOE (double open ended) cartridges have a flat gasket at each end and are clamped between the head and bowl of a standard housing. This is the most common fit for 10" and 20" housings. 226/Fin cartridges have two 226-size O-rings and a locating fin that locks into the housing, giving a positive seal that stops water bypassing the filter. They're typically used in industrial stainless steel housings. The two styles aren't interchangeable, so check your existing cartridge or housing before ordering.
