STEEL FILTER DISC 4X3 20MICRON

The STEEL FILTER DISC 4×3 20MICRON is a miniature sintered metal powder filter element designed for precise and compact filtration in high-accuracy gas and liquid flow systems. Manufactured from stainless steel powder by sintering, this ultra-small disc offers a nominal 20-micron pore size for consistent particle removal.

Its compact size—4 mm diameter and 3 mm thickness—makes it ideal for integration in micro devices, sensor housings, miniature regulators, or dosing equipment where filtration performance and spatial efficiency are critical. The uniform porosity enables effective depth filtration with minimal flow restriction.

The stainless steel powder body ensures chemical resistance, thermal stability, and mechanical integrity. It supports repeated cleaning cycles, making it a sustainable solution in sensitive and precision-controlled environments.

FAQ

Q1: What is this sintered metal powder disc used for?
It’s used in compact equipment to filter particles from gases or fluids before reaching sensitive components.

Q2: Can this micro disc be reused?
Yes. Despite its small size, it’s fully reusable via ultrasonic cleaning, backflushing, or solvent soaking.

Q3: Is the 20µm pore size suitable for sensor protection?
Yes. It’s ideal for filtering medium to fine particles and protecting pressure or gas sensors from contamination.

Q4: Will the small disc cause pressure drop?
Not significantly in low-flow or micro-flow applications. Its porosity and small thickness minimize restriction.

Q5: Are custom diameters or pore sizes available?
Absolutely. DALON manufactures custom powder filter discs in various dimensions and micron ratings as needed.
