SINTERED STAINLESS STEEL 316L FILTER DISC 20X3 0.5MICRON

The SINTERED STAINLESS STEEL 316L FILTER DISC 20×3 mm 0.5MICRON is a precision flame arrestor disc designed for gas containment and explosion prevention. With a 0.5 micron nominal pore rating, it effectively disrupts flame fronts and stops flashback propagation in fuel gas, exhaust, or vent systems.

Made from 316L stainless steel powder, sintered into a robust and uniform porous structure, the disc withstands extreme heat and pressure. This high-performance material resists thermal deformation, oxidation, and corrosive gases, making it ideal for critical safety applications.

Its 20 mm diameter and 3 mm thickness offer a compact profile that can be mounted inline or embedded within valves, sensor ports, pressure relief housings, or vent lines. The fine porosity absorbs combustion energy and dissipates flame velocity—meeting safety needs in industrial systems handling flammable or reactive gases.

It is also backflushable and reusable, making it a cost-effective and durable option in hazard-prone process environments.

FAQ

Q1: What is the role of this disc as a flame arrestor?
It interrupts flame fronts by absorbing combustion energy within its fine porous metal structure, stopping flame propagation into protected areas.

Q2: Is 0.5µm filtration necessary for arrestor function?
Yes. Smaller pores enhance the filter’s ability to cool flame fronts and disrupt flashback, improving safety.

Q3: Can this be cleaned and reused?
Absolutely. It is fully cleanable by backflushing, solvent soaking, or ultrasonic baths, enabling long-term reuse.

Q4: Will this disc work in high temperature exhaust lines?
Yes. 316L stainless provides excellent thermal and structural stability up to 600°C, suitable for hot gas environments.

Q5: Can it be welded into a custom housing?
Yes. DALON supports OEM customizations, including welding, brazing, and housing-integrated arrestor disc assemblies.
