String wound filter cartridges are available in a wide range of filter media, allowing them to adapt to a great variety of applications and operating conditions, including temperature ranges and chemical compatibility.
Filter Media Types
Polyester: Offers greater temperature resistance than polypropylene.
Fiberglass: Used for high-temperature applications and corrosive services.
FDA Cotton Bleached General-purpose medium, with variations for applications such as distilled water, beverages, and organic solvents.
Nylon and Rayón (Rayon/Artificial Silk): For special process applications, including concentrated bases and organic solvents.
Ryton (PPS): Designed for challenging chemical compatibilities at elevated temperatures.
General Applications
Aqueous and Potable Liquids: Water, drinking water (potable water), distilled water, and beverages.
Chemicals and Solvents: Organic acids, bases (alkalis), alcohols, amines, glycols, and organic solvents.
Oils and Greases: Animal and vegetable oils, animal fats, and thermal media fluids.
Special/Industrial: Food processing, pharmaceuticals, saltwater disposal, lead-acid batteries, and corrosive services.
Physical and Operational Specifications
Despite differences in material, operational specifications are largely uniform across the different types of string wound cartridges, with the main difference being the Maximum Temperature:
