Porous Stainless Steel Isostatic Tubes (IS)

Our standard products are covering a wide range of applications. Customized design available upon request.


316 L construction per default.
304 L / Inconel 600 / Monel 400 or Hastelloy on request.

Features & Benefits

Basic shape for standard candles (BI) or cartridges (CRI, CFI and DOE).

• Good durability against most aggressive fluids,
• Usable over a wide range of temperatures,
• High mechanical resistance,
• Regenerable through backflush / chemical / thermal or ultrasonic treatment.

Retention rates

8 PORAL grades available - see PORAL grades definition table for detailed information.
In liquids, retention at 98% of solid particles from 3,2 μm (PORAL grade 03) to 90 μm (PORAL grade 40). In gases, retention at 98% of solid particles from 0,2 μm (PORAL grade 03) to 8 μm (PORAL grade 40).
