STEEL FILTER DISC 140X3 30MICRON

DALON’s 30µm porous stainless steel filter disc, sized 140 mm diameter × 3 mm thickness, is designed for robust and consistent filtration in industrial gas, air, and liquid systems. Manufactured using sintered stainless steel powder, this disc provides a rigid and corrosion-resistant filtration solution with uniform pore structure across the surface.

The large format and 30-micron filtration accuracy make this filter ideal for use in pre-filtration, diffusion plates, pressure equalizing systems, and gas/liquid dispersion applications. Its rigidity allows it to withstand mechanical stress, thermal cycles, and chemical exposure—making it a reliable option for challenging environments where filter failure is not an option.

Whether used as a standalone disc or integrated into a multi-layer assembly, this porous stainless steel filter ensures steady flow, low pressure drop, and efficient removal of particulates. It supports backwashing, ultrasonic cleaning, or solvent rinsing, making it suitable for multiple filtration cycles with minimal maintenance.

FAQ – Frequently Asked Questions

Q1: What does a 30µm stainless steel filter disc remove?
It captures medium-sized particles such as rust, dust, sediment, and process residues from gases or liquids.

Q2: Is this filter reusable?
Yes. The sintered structure allows for cleaning using water, air, or solvents. It withstands multiple cleaning cycles.

Q3: Can it handle corrosive or high-temperature environments?
Absolutely. Made from SS316L, it is resistant to acids, bases, heat, and mechanical impact.

Q4: How is this different from wire mesh filters?
Unlike mesh, sintered metal offers depth filtration, higher structural strength, and better pore uniformity for consistent performance.

Q5: Can I get this filter in other sizes or micron ratings?
Yes. DALON offers custom sizes, shapes, and porosity levels from 0.5 to 100 microns, including engineering support for tailored solutions.

Q6: What industries use this type of filter?
Common in chemical processing, water treatment, gas dispersion, environmental testing, lab instrumentation, and food/beverage systems.

Q7: What is the delivery time for standard or custom filters?
Standard filters ship in 30 days. Custom-designed products with new tooling require 35–40 days, including mold fabrication.
