STEEL FILTER DISC 70X4.5 0.5MICRON

DALON’s 70×4.5 mm sintered SS316 powder filter disc with 0.5-micron nominal filtration provides exceptional particle retention and ultra-fine filtration performance for critical fluid and gas applications. Engineered from sintered 316L stainless steel powder, this disc features a rigid and uniformly porous structure that ensures high stability under pressure, temperature, and corrosive conditions.

With such a fine 0.5μm rating, it’s ideal for capturing ultra-fine particles such as aerosols, bacteria, and submicron contaminants. The disc’s sintered structure delivers not only depth filtration but also superior flow distribution and minimal channeling—essential for systems demanding precision and purity.

Its diameter and thickness make it suitable for analytical equipment, semiconductor processing, pharmaceutical filtration, and high-purity gas/liquid control systems. This stainless steel filter disc is washable, sterilizable, and supports multiple usage cycles—ensuring long service life and reduced operational cost.

FAQ – Frequently Asked Questions

Q1: What contaminants does a 0.5µm filter remove?
It filters out ultra-fine dust, bacteria, smoke particles, and other submicron particulates from air or fluid streams.

Q2: Can this filter be sterilized for reuse?
Yes. It can be sterilized via autoclaving, high-temperature baking, or chemical disinfection.

Q3: Is SS316L resistant to aggressive media?
Yes. SS316L provides excellent resistance to acids, alkalis, oxidizers, and saline conditions.

Q4: How does this compare to membrane filters?
While membrane filters offer surface filtration, sintered metal discs provide depth filtration, structural durability, and are reusable.

Q5: What industries benefit from this type of filter?
Used in semiconductor manufacturing, biotechnology, pharmaceuticals, lab instruments, gas metrology, and analytical chemistry.

Q6: Can I customize the filter's pore size or shape?
Absolutely. DALON supports tailored pore ratings, thicknesses, and edge treatments for OEM and industrial needs.

Q7: What is the lead time for delivery?
Standard sizes ship in 30 days; custom designs (with mold fabrication) are ready in 35–40 days.
