STEEL FILTER DISC 22X2 20MICRON

DALON’s 20µm inox filter disc, precisely sized at 22 mm diameter and 2 mm thickness, is a compact and reliable filtration element designed for fine particulate removal in industrial and fluid handling systems. Constructed from sintered stainless steel, often referred to as “inox”, this disc delivers excellent filtration performance, structural strength, and chemical resistance in both air and liquid environments.

The porous metal structure is engineered through sintering fine stainless steel powders, creating a uniform and rigid disc with interconnected pores that enable controlled flow and particle retention. This filter disc performs effectively in high-temperature, corrosive, or high-pressure applications where polymer or fiber-based filters would fail.

The 22×2 mm form factor is ideal for integration into valves, regulators, manifolds, sample lines, and other compact assemblies. It can function as a pre-filter, protective screen, or final barrier in gas, oil, solvent, or water systems—across industries such as automation, analytical instrumentation, fuel systems, and HVAC.

FAQ – Frequently Asked Questions

Q1: What does a 20µm inox filter remove?
It effectively traps fine particles like rust flakes, debris, dust, or micro-resins from liquids or gases.

Q2: Is this disc reusable?
Yes. It can be cleaned using compressed air, backflushing, or chemical washing depending on the media.

Q3: Can I use it in high-temperature or corrosive environments?
Absolutely. Inox steel offers excellent performance in heat, pressure, and chemical exposure scenarios.

Q4: How is this different from mesh filters?
Unlike woven mesh, sintered inox filters have depth filtration with tortuous pore paths for higher contaminant capture and mechanical strength.

Q5: Can DALON customize pore size or shape?
Yes. We offer sintered discs in custom thickness, diameter, micron rating, and even non-circular shapes on request.

Q6: What’s the typical delivery time?
Standard items ship in 30 days, while custom designs (including mold/tooling) are completed in 35–40 days.

Q7: What industries use inox filter discs?
Commonly used in automation, filtration skids, gas sampling, chemical dispensing, and instrumentation systems.
