Since 1998, Anping County Boli Hardware Wiremesh Products Factory has been a reliable manufacturer of industrial filtration solutions, exporting to over 15 global markets with an annual export value of US$5-10 million. Our 316L Stainless Steel Johnson Filter, 0.5mm Opening, 2" Flange, 10 Bar Pressure is engineered for demanding applications requiring precise solids separation and long service life. Crafted from premium-grade 316L stainless steel, this wedge wire filter resists corrosion in aggressive environments, while the 0.5mm slot opening ensures consistent filtration of fine particles. The 2" flange connection simplifies installation into existing piping systems, and the 10-bar pressure rating supports high-flow operations without compromising structural integrity.

Key Features & Technical Specifications

Material Excellence: 316L stainless steel contains molybdenum, offering superior resistance to chlorides, acids, and high-temperature environments compared to standard 304 stainless steel.
Precision Slot Opening: 0.5mm (500 micron) continuous slot width, manufactured with tight tolerances (±0.02mm) to ensure uniform filtration and minimize blinding.
High Flow Capacity: Wedge wire profile design provides a larger open area than traditional mesh screens, reducing pressure drop and increasing throughput.
Robust Connection: 2-inch flange (ANSI/DIN standards available) with raised face and bolt holes for secure, leak-proof sealing.
Pressure Rating: Rated for 10 bar (145 psi) operating pressure, suitable for medium-pressure water, oil, and chemical applications.
Customizable Dimensions: Available in various lengths (standard 1m, 2m, or custom), diameters (from 50mm to 300mm), and end connections (threaded, grooved, or flanged).
Surface Finish: Pickled and passivated or electropolished to resist fouling and facilitate cleaning.

Benefits to Your Application

Extended Service Life: 316L stainless steel resists pitting and crevice corrosion, reducing replacement frequency in chlorinated water or chemical injection systems.
Reduced Maintenance: Continuous slot design allows easy backwashing; debris slides off the wedge wire surface, minimizing clogging.
Efficient Filtration: 0.5mm opening captures sand, silt, and small particulates while maintaining high flow rates – ideal for well water intake, irrigation, and industrial process water.
Easy Integration: Standard 2" flange matches common pipe sizes; optional gasket materials (EPDM, Viton, PTFE) available for chemical compatibility.
Cost-Effective: Lower pressure drop means reduced pumping energy; long lifespan lowers total cost of ownership.

Frequently Asked Questions

Q: What is the difference between a Johnson filter and a standard wire mesh screen?
A: Johnson filters use a continuous wedge wire profile wound around support rods, creating a V-shaped slot. This design provides a larger open area, higher strength, and better resistance to clogging compared to woven mesh screens. The 0.5mm slot width is precise and non-clogging.
Q: Can this filter be used for drinking water applications?
A: Yes, 316L stainless steel is safe for potable water. The surface finish can be electropolished to meet hygiene standards. However, we recommend confirming local regulations for drinking water contact materials.
Q: What is the maximum flow rate for this filter?
A: Flow rate depends on filter length, diameter, and slot open area. For a standard 1m length, 100mm diameter, the flow rate at 10 bar can exceed 50 m³/h for clean water. Contact us with your specific parameters for a precise calculation.
Q: Do you offer non-standard flange sizes or pressure ratings?
A: Yes, we can customize the flange to ANSI 300#, DIN PN16, or other standards. Pressure ratings up to 20 bar can be achieved with thicker wall support rods. Please provide your requirements.
Q: How do I clean the filter if it becomes clogged?
A: The filter can be backwashed with water or air. For stubborn deposits, chemical cleaning with mild acids or alkaline solutions (compatible with 316L) is effective. The smooth wedge wire surface facilitates cleaning.
Q: What is the lead time for this product?
A: For standard sizes (1m length, 100mm diameter, 2" flange), lead time is typically 15-20 working days. Custom orders may require 25-35 working days depending on complexity.
Q: Can you provide a material certificate?
A: Yes, we can provide a mill test certificate for 316L stainless steel upon request. Additional third-party inspection (e.g., SGS, BV) is available at extra cost.
Q: What packaging is used for export?
A: Each filter is individually wrapped in plastic, then packed in wooden crates or cartons with foam protection. We ship from Tianjin, Qingdao, Shanghai, or Foshan ports, with FOB or CIF terms.
