Since 1998, Anping County Boli Hardware Wiremesh Products Factory has been a trusted manufacturer of industrial filtration solutions. Our Stainless Steel Wedge Filter (Johnson Filter) is engineered to deliver reliable performance in demanding environments. With a 2-year warranty and free technical support, we ensure your investment is protected. This product complies with industry standards, making it a cost-effective choice for water treatment, oil & gas, and mining applications.
The wedge wire construction provides exceptional strength and precision filtration.

Applications & Benefits
Our Johnson filter is widely used in:
- Water Treatment: Sand removal, intake screening, and wastewater filtration.
- Oil & Gas: Downhole sand control, gravel pack screens, and produced water filtration.
- Mining & Minerals: Dewatering, slurry screening, and particle classification.
- Food & Beverage: Juice, syrup, and beer filtration with high hygiene standards.
- Chemical Processing: Catalyst recovery, liquid-solid separation, and acid filtration.
Why choose our wedge filter? The continuous slot design offers a larger open area compared to perforated screens, resulting in higher flow rates and lower pressure drops. The V-shaped profile prevents particles from wedging inside, reducing cleaning frequency. Additionally, the stainless steel construction ensures long service life even in abrasive environments.
