STEEL FILTER TUBE 21X26X30 5MICRON

DALON’s STEEL FILTER TUBE 21×26×30 5MICRON is a compact, high-efficiency sintered porous air filter engineered for reliable 5µm particle removal in industrial gas or air filtration applications. Designed with a 21 mm inner diameter, 26 mm outer diameter, and 30 mm length, it’s ideal for use in confined spaces or compact filter housings that demand consistent airflow with fine filtration.

Constructed from sintered stainless steel powder, this filter tube features a uniform porous matrix, providing depth filtration to trap particles both on the surface and within the structure. This enhances filtration efficiency and extends service life compared to surface-only filters.

The 5-micron rating makes it particularly suitable for protecting sensitive pneumatic components, flow sensors, valves, and precision instruments from fine dust, aerosols, and oil mist. The filter's mechanical strength ensures reliable operation in high-pressure or vibration-prone environments.

Reusable and corrosion-resistant, the filter supports cleaning through ultrasonic, solvent, or backflushing methods, reducing maintenance costs and increasing longevity in continuous operations.

FAQ – Frequently Asked Questions

Q1: What does a 5µm sintered air filter capture?
It removes fine particles ≥5 microns, ideal for oil mist, dust, and debris in gas and air lines.

Q2: Can this filter tube be reused?
Yes. It is cleanable using ultrasonic baths, chemical soaking, or reverse flushing.

Q3: What environments is this filter suitable for?
It handles corrosive, high-pressure, and high-temperature conditions due to its 316L stainless structure.

Q4: Will the filter restrict airflow?
The porous structure is optimized for minimal pressure drop while maintaining effective filtration.

Q5: Can DALON provide other sizes or micron ratings?
Absolutely. Custom dimensions, pore sizes, and OEM labeling are available.
