BRONZE FILTER CARTRIDGE 3.35X6.35X6.2 30MICRON

DALON’s 3.35×6.35×6.2 mm Bronze Air Filter Cartridge is a miniature, sintered metal filtration element designed for fine air and gas purification in compact or precision systems. Manufactured from sintered bronze using advanced powder metallurgy techniques, this filter achieves 30-micron nominal filtration accuracy while maintaining excellent structural integrity and airflow efficiency.

The bronze matrix consists of evenly distributed micro-pores, providing depth-type filtration that captures airborne particles such as dust, scale, and condensate droplets. Its compact form factor makes it ideal for valves, regulators, sensors, and pneumatic components where limited space and high reliability are key considerations.

This bronze air filter is commonly press-fitted into tight chambers or mounted inside sensor ports, providing not only filtration but also acoustic damping in air discharge lines. With its natural corrosion resistance, thermal stability, and reusable nature, this cartridge filter is well-suited for OEM applications requiring long service life with minimal maintenance.

FAQ – Frequently Asked Questions

Q1: What does a 30µm bronze air filter remove?

It effectively removes fine particles such as dust, rust, or metal flakes from compressed air or gas streams before reaching sensitive system components.

Q2: Is this filter suitable for compressed air systems?

Yes. Its sintered bronze construction ensures low pressure drop, thermal resistance, and long-term durability even in dry or lubricated compressed air setups.

Q3: Can this be reused after cleaning?

Absolutely. The filter is washable and supports cleaning by backflushing, ultrasonic cleaning, or mild solvents depending on contamination type.

Q4: How is this bronze filter installed?

Typically press-fitted into a housing or tube. Its dimensions allow secure installation in precise bores, chambers, or manifolds.

Q5: Is this suitable for use in oxygen or reactive gas systems?

Sintered bronze is generally compatible with non-aggressive gases. For high-purity or oxygen-rich systems, additional surface treatment or testing may be required.

Q6: Can I get this in a custom size or porosity?

Yes. DALON offers full customization for ID/OD/length, micron grade, and shape configurations. Contact us for design assistance.

What Do People Also Ask? (Expanded Q&A)

Q: What is the difference between a bronze filter and a brass filter?

While both may appear similar, bronze is typically stronger and more resistant to corrosion under pressure. Sintered bronze filters are preferred for industrial air and gas applications due to their superior porosity and mechanical strength.

Q: Are bronze filters better than plastic filters?

Bronze filters offer higher thermal resistance, mechanical durability, and longer service life, making them ideal for high-pressure or high-temperature environments.

Q: How do I choose the right micron size for an air filter?

Micron selection depends on your application’s particle size tolerance. 30µm is suitable for general-purpose air filtration; for finer protection, consider 5–10µm.
