Filter Screens

Pricing varies widely based on material grade (such as SS304 versus SS316), wire thickness, mesh density, and order volume. Custom-configured filter screens with tight porosity tolerances or specialty alloys generally cost more than standard stock mesh. For an accurate quote, manufacturers typically require specifications like dimensions, material, and application before providing pricing.

While standard window screens primarily keep out insects, specialized knitted wire mesh filter screens can be engineered for air filtration, capturing airborne particulates while maintaining airflow. These differ from typical residential window screens and are generally used in industrial ventilation, HVAC, or equipment enclosures rather than home windows.

Filter screens are commonly manufactured from stainless steel grades like SS304 and SS316 for corrosion resistance and strength. Other materials include brass, copper, aluminum, and engineered polymers for specialized chemical resistance. Material selection depends on the operating temperature, chemical exposure, and mechanical stress the filter screen will encounter in service.

Porosity is controlled during the knitting or weaving process by adjusting wire diameter, mesh density, and compression. Manufacturers can achieve void volumes ranging from near-zero to over 98%, allowing engineers to fine-tune flow rates and particle capture efficiency for specific filtration, separation, or mist elimination requirements.

Standard knitted wire mesh filter screens typically use wire thicknesses between 0.10mm and 0.30mm, with some custom applications extending up to 0.36mm. Thinner wires yield finer filtration and greater flexibility, while thicker wires provide added durability for high-vibration or high-pressure industrial environments.

Yes, knitted and compressed wire mesh filter screens can be fabricated into rings, rectangular panels, gaskets, seals, and other custom shapes to fit specific equipment geometries. This flexibility allows engineers to integrate mesh filtration directly into vessels, columns, exhaust systems, and mechanical assemblies without extensive redesign.
