STEEL I filters are fully constructed from welded stainless steel, without adhesives or binding agents, ensuring mechanical strength and long-term reliability in demanding process environments. Built to handle extreme operating conditions, it withstands temperatures from –260°C up to 370°C and differential pressures as high as 16 bar. Its multi-layer pleated structure maximizes surface area and ensures high flow capacity, even under heavy particulate load. Designed for use in chemically aggressive, high-viscosity, or thermally extreme processes, this filter offers reliable performance across a wide range of industrial, petrochemical, and high-purity applications. Optional configurations like denser pleats, external mesh layers, or microfiber materials are also available to meet more specific performance needs.
- All-metal Construction: This filter is made from AISI 316L stainless steel, providing strong mechanical support and lasting durability in demanding process environments.
- Extended Surface Area: A multi-layer pleated layout increases the filtration surface, which helps retain more particles while keeping flow resistance low.
- Stable Under Extreme Conditions: The filter works reliably with both aggressive fluids and a wide range of temperatures, from deep-cold to high-heat applications.
- Reusable Across Cleaning Cycles: After use, the filter can be cleaned and returned to service through chemical rinses, heating, or mechanical methods depending on setup.
- Fits Across Many Systems: It connects easily with various housings and seal types, helping simplify replacement and reduce setup time across installations.
- Performs in Challenging Flows: Even when used with thick or contaminated liquids, the filter continues to operate consistently without frequent clogging.
- Sintered Wire Mesh: Made from vacuum-bonded layers of stainless steel mesh, this media offers strength, uniform pore structure, and resistance to collapse under pressure.
- Dense Pleat Configuration: An optional, tighter pleat pattern allows for depth-style retention and improved performance in finer filtration tasks.
- Metal Microfiber Media: Available as an alternative to mesh, this fine fiber material provides higher flow rates with excellent retention efficiency.
- Outer Protection Net: The optional external net provides additional mechanical support and protection in high-pressure or abrasive applications.
- Chemical and Petrochemical Processes: Designed to handle corrosive fluids, solvents, and aggressive hydrocarbons used in refining and chemical synthesis.
- High-temperature Filtration: The stainless steel filter can withstand extreme heat, making it suitable for filtering thermal oils, steam, and heated process fluids.
- Viscous Fluid Processing: Ideal for thick liquids such as oils, syrups, polymers, and coatings where flow and stability are critical.
- Pharmaceutical Intermediates: Supports filtration of solvents, intermediates, and other non-sterile components in pharmaceutical manufacturing.
- Industrial Gas and Steam Lines: Used in high-purity or utility-grade gas systems to protect downstream equipment from particulate contamination.
