Stainless steel cartridges are intended to overcome the temperature and chemical compatibility limitations of fabric or synthetic fiber media. This will offer very hightemperature resistance & can even withstand high differential pressure. Stainless steel cartridges are provided in Stainless steel grade 304, Also known as SS 316, & ss 316 l materials. These elements can be either plain cylindrical or in pleated configuration to increase filtration all stainless, Area. Usually steel pleated & cylindrical filters are supported with coarser filter media to ensure no direct damage is inflicted to main filtering media under process upsets. A bubble point test can be done to certify that no opening larger than the specified pore size exist in product joints or seams. No media migration occurs due to stainless steel material. These elements can be back washed & reused.
