Demands for the sterilization of compressed air and gas in the food industry, dairies and breweries are continuously increasing. Complete retention of micro-organisms such as bacteria, viruses and bacteriophages; the largest possible filter area; low differential pressure; and cost effectiveness are standard requirements that a filter must meet.

Parker Zander ST-R Series Air Sterilization Filter Cartridges utilize a borosilicate glass microfiber medium. This medium has proven to be particularly effective in the removal of sub-micron particles as small as 0.01 micron, ensuring the removal of all micro-organisms, including bacteria and viruses.

ST-R Series Filter Cartridges are particularly suitable for the increasing number of high-temperature applications. They also fulfill the sterility requirements for compressed air and gas in the dairy, brewery and food process industries.
