Stainless Steel Filter Cartridges

• Sintered filters fuse layers of stainless steel powder for depth filtration with high structural strength and microporosity.
• Pleated fibre filters use stainless steel mesh or fibre felt in pleated form, offering large surface area and dirt-holding.
• HighFlow Pleated filters are larger pleated versions designed for very high flow rates with minimal pressure drop.

Choose based on:

• Particle size: For sub-micron control, sintered filters are best. Pleated types excel for larger particles or high-flow.
• Flow rate and pressure drop: HighFlow pleated filters offer low resistance at large volumes.
• Cleaning method: All stainless types are cleanable, but sintered is easiest to back-wash; pleated is suitable for ultrasonic cleaning.

Common sectors include:

• Food & Beverage (hygienic steam, syrup clarification)
• Pharmaceutical & Biotech (steam sterilisation & high-purity fluids)
• Chemical Processing (handling corrosive solvents)
• Oil & Gas (hydraulic fluids, pneumatic systems)
• Power & Steam (boiler feed water filters)

Micron ratings range from 0.5 µm (fine sintered filters) to 500 µm (low-grade pleated fibres). Sintered filters typically span 0.5–50 µm, while pleated options cover 3–200 µm for broader debris capture.

Yes. Cleaning options include:

• Back-flushing: Ideal for sintered filters.
• Ultrasonic or hot-water cleaning: Works well for pleated filters.
• Chemical soak: For sticky residues or oils.

Absolutely. Depending on grade and design, they operate up to 600 °C and 10–40 bar (or more with custom builds). HighFlow pleated filters also maintain structural integrity under significant pressure differentials.

Common options include SOE 222/226, Highflow styles, threaded ends such as BSP and NTP.

They are produced by layering stainless steel powder material (or fibres), compressing, and sintering at high temperatures. This fuses particles into a rigid, porous matrix—ideal for depth filtration, high strength, and microporosity.

They consist of a stainless mesh or felt media pleated to increase surface area. The fibre form provides a gradation of particle capture, making them effective across a wide range of particle sizes with low initial pressure drop and high dirt-holding.

316/316L is industry-preferred for superior corrosion resistance, though 304 is sufficient for general use. Specialty alloys (e.g., Hastelloy) are available for severe chemical environments.

Stainless steel filters typically last 5–10 years, depending on usage and maintenance. In contrast, plastic ones might need frequent replacement. The ability to clean and re-use saves on lifecycle costs.
