Product Description

Exhaust Filter Disc for Engines, Valves & Emission Units

STEEL FILTER DISC 51X3 20MICRON Additional image 1

DALON’s STEEL FILTER DISC 51×3 20MICRON is a robust, reusable exhaust gas filter engineered to provide 20-micron filtration for high-temperature gas systems. Manufactured from sintered stainless steel powder (typically SS316L), this disc offers exceptional resistance to heat, corrosion, and pressure, making it ideal for exhaust emission control and gas purification systems.

With a 51 mm diameter and 3 mm thickness, this disc delivers consistent flow performance while effectively removing particulate matter from exhaust streams. Its sintered structure offers uniform pore size, mechanical rigidity, and long-term reusability without risk of deformation or clogging.

This filter disc is suitable for use in combustion engines, industrial burners, flue gas lines, or chemical reaction systems, where gas cleanliness, temperature stability, and durability are mission-critical.


Key Features:

  • Material: Sintered Stainless Steel (typically SS316L)

  • Size: 51 mm diameter × 3 mm thickness

  • Filtration Rating: 20 microns

  • Structure: Porous sintered matrix for depth filtration

  • Thermal Resistance: Stable under high exhaust gas temperatures

  • Chemical Resistance: Withstands acidic or corrosive emissions

  • Reusable: Supports backflushing, ultrasonic, and chemical cleaning

  • Low Pressure Drop: Maintains efficient flow under load

  • Application Fit: Combustion exhaust, emission control, gas scrubbing


Common Applications:

  • Internal combustion exhaust systems

  • Burner or incinerator exhaust filters

  • Chemical plant emission control

  • Gas sample conditioning units

  • Catalytic converter pre-filtration

  • Industrial gas dryers and scrubbers


FAQ – Frequently Asked Questions

Q1: What is this 20-micron exhaust gas filter used for?
It captures particulates from exhaust gas streams to protect equipment, reduce emissions, or prepare gases for further filtration or analysis.

Q2: Can the disc handle high temperatures?
Yes. Made from SS316L, it is suitable for sustained use in high-temperature exhaust gas environments.

Q3: Is the filter reusable?
Absolutely. It can be cleaned and reused across multiple cycles, supporting ultrasonic and solvent cleaning methods.

Q4: What’s the benefit of sintered stainless steel over mesh?
Sintered filters provide depth filtration, fixed pore size, and higher mechanical strength with no risk of media migration.

Q5: Can DALON customize this disc for different systems?
Yes. Custom pore sizes, diameters, materials, and mounting options are available based on your system’s requirements.
