Stainless Steel 904L Filter Nozzle: a reliable, long-lasting solution engineered for the most demanding filtration needs, used for water treatment, chemical processing, or industrial applications
904L stainless steel is a premium austenitic alloy with a specialized chemical composition: rich in chromium (19-23 %), nickel (23-28 %), molybdenum (4-5 %), and a touch of copper (1-2 %). Compared with the more common SS316L grade, it offers far superior resistance to pitting, crevice corrosion, chloride-induced stress corrosion cracking, and reducing acids. In short, 904L combines exceptional corrosion resilience with long-term reliability.
Structural Excellence & Design Features
Our wedge wire filter nozzle design uses precision V-profile wires welded to support rods. The configuration ensures strong mechanical integrity, high open area for fluid flow, and resistance against clogging.
This robust design enables:
• Large flow capacity with low pressure drop
• Accurate slot filtration and high efficiency
• Easy backwashing and maintenance
• Solid construction resisting high pressure, temperature, and chemical exposure.
Product Types Available
We offer a versatile lineup to suit your filtration system:
✔ Single-head filter nozzles
✔ Double-head filter nozzles
✔ Long-handle nozzles
All are crafted from 904L stainless steel and can be custom-designed to your specifications.
Where These Nozzles Excel
Thanks to their material strength and design, 904L filter nozzles shine across a variety of demanding industries:
• Water treatment & desalination: leveraging chemical resistance and durability to improve system performance.
• Chemical processing & solvent filtration: ideal for aggressive environments like Methyl Ethyl Ketone (MEK) filtration.
• Ballast water management: used in maritime systems where long-term corrosion resistance is critical.
• Food, beverage, and pharmaceuticals: offering hygienic, long-lasting performance.
Additional applications include power generation, petrochemical filtration, and industrial wastewater management.
| Benefit | Why It Matters |
| Corrosion & Chemical Resistance | Unmatched durability in harsh and chloride-rich environments |
| Long Service Life | Reduced replacements, lower maintenance, and cost-efficiency |
| High Filtration Precision | Effective removal of fine particulates with low clogging risk |
| Versatile Designs | Fit for diverse systems—from municipal plants to industrial reactors |
| Customizable Options | Tailored to your flow, slot size, and connection requirements |
While 316L stainless steel is a reliable choice for many filters, 904L outperforms it in terms of longevity and corrosion resistance, particularly in environments with high chloride levels or acidic conditions. The marginally higher cost is quickly offset by less maintenance, longer intervals between replacements, and superior performance.
If you're seeking a high-performance, corrosion-resistant solution that combines durability with precision, the Stainless Steel 904L Filter Nozzle should be your first choice.
