What is stainless steel filter nozzle?
A stainless steel filter nozzle is a key filter element used for liquid collection, water distribution, air distribution, and preventing filter media loss. It is widely used in filtration equipment in water treatment, chemical, food, and environmental protection industries.

I. Core Functions
- Water Collection and Distribution: During filtration or ion exchange, it evenly collects treated clean water or evenly distributes inlet/backwash water, preventing short-circuiting and improving treatment efficiency.
- Preventing Filter Media Loss: Through precise slit design (typically 0.2mm~3mm), it effectively intercepts particulate filter media such as quartz sand, activated carbon, anthracite, and resin, allowing only liquid to pass through.
- Air Distribution: In air-water backwashing systems, it evenly distributes compressed air, ensuring thorough and uniform cleaning of the filter media layer.
II. Why Choose Stainless Steel?
- Corrosion Resistance: 304/316/316L stainless steel resists corrosion from acids, alkalis, chloride ions, and seawater, resulting in a long service life. High Strength: Withstands heavy pressure from filter media layers (up to several meters thick) and backwash water/air impact.
- High Precision: Wedge-shaped wire or perforated structure with uniform gaps (0.1mm~6mm), ensuring high interception accuracy and preventing clogging.
- Easy to Clean: Smooth surface, easy to rinse during backwashing, and less prone to scaling.
- Hygiene and Safety: Meets food-grade and drinking water standards, with no harmful substances leaching out.
