Wedge Wire & Baskets — Single-Layer Series
SS316L Stainless Steel — Industrial Filtration
Product Overview
Notch wire filters use a single wound profile wire wound around a cylindrical frame, creating precise rectangular slot openings compared to standard cylindrical filters, resulting in higher flow rates and longer service life. They are ideal for applications requiring precise filtration under harsh operating conditions such as food and pharmaceutical processing and high-viscosity fluid filtration.
The single-layer wound construction maximizes open area, delivering high flow rates with minimal pressure drop. All components are constructed from SS316L stainless steel, providing excellent corrosion resistance for demanding sanitary and industrial applications. The open structure enables full visual inspection of cleaning effectiveness — a key advantage over multi-layer alternatives.

Product Advantages
3–5× the effective filtration area of standard cylindrical filters in the same housing envelope, reducing pressure drop significantly.
Single-layer structure allows impurities to be easily eliminated by air blowing or simple backflush — cleaning effectiveness is visually checkable, reduces replacement frequency, and lowers overall operating costs.
Single-layer wire construction maximizes open area for high flow rates with minimal pressure drop, pleated stainless steel filters can be reused across multiple service cycles.
SS316L construction with operating range from -268℃ to +371℃. Compatible with acids, solvents, hydrocarbons, and industrial chemicals.
All our stainless steel filters undergo notch wire slot size can be verified visually and cleaning effectiveness confirmed through the transparent design to remove free iron residues — ensuring corrosion resistance and preventing contamination. Each unit is verified with up to 200-point surface cleanliness test per kit before packaging.

Technical Support
Wedge wire uses triangular profile wire creating V-shaped slots with continuous self-cleaning action. Notch wire uses a single rectangular profile wire wound around a frame, creating rectangular slot openings. Notch wire is simpler, easier to clean via air blowing, and better suited for sanitary food and pharmaceutical applications.
Because the notch wire element has a single-layer structure, impurities adhered to the wire surface are easily dislodged by a burst of compressed air or backflush liquid. The open structure allows full visual inspection of cleaning effectiveness — a key advantage for sanitary applications.
Standard slot sizes range from 0.1mm to 3mm. Custom slot sizes are available. The slot opening remains precisely constant even after repeated cleaning and reuse — unlike some mesh filters that can deform.
Yes. Notch wire filters are widely used in the food, beverage, and pharmaceutical industries. The single-layer structure allows complete drainage and full visual inspection of cleanliness. SS316L construction ensures corrosion resistance and compatibility with sanitary processes.
Notch wire filters handle differential pressures up to 25 bar depending on the element diameter and support structure. The single-layer wire design is robust but typically rated lower than multi-layer wedge wire screens.
Initial samples: 48-72 hours after drawing confirmation. Custom slot sizes and non-standard diameters: typically 5-7 days. No minimum order quantity for prototype samples.
