Micro-Klean(TM) CS series filters are an improved conventionally wound cartridge. The materials of construction (core and roving) offer broad chemical compatibility and economical filtration. Continuous length winding eliminates the dead spots found on conventionally wound cartridges. A single roving strand employs a strictly controlled material to produce a consistent and high quality cartridge.
