Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer since 1998, proudly presents our Wedge Wire Johnson Filter, 304 Stainless Steel, 0.3mm Slot, 2m Length, specifically engineered for food processing applications. This filter combines precision slotting with robust construction to deliver reliable separation and efficient flow in demanding environments. With over two decades of wire mesh expertise and annual export value reaching US$5-10 million, our factory ensures consistent quality and global compliance.
Our Johnson filter is designed using continuous wedge wire wound around support rods, forming a V-shaped profile that minimizes clogging and maximizes open area. The 0.3mm slot width allows precise particle retention while maintaining high throughput, making it ideal for food processing stages such as juice clarification, syrup filtration, starch washing, and wastewater treatment. The 304 stainless steel construction offers excellent corrosion resistance and food-grade hygiene, meeting the stringent requirements of the industry.
Key features of our wedge wire Johnson filter include:
- Precision Slot Width: 0.3mm ±0.02mm, ensuring consistent particle retention and high separation efficiency.
- Non-Clogging Design: V-shaped wedge wire profile allows particles to slide off, reducing blinding and maintenance downtime.
- High Strength: Continuous resistance welding of wedge wire to support rods creates a rigid structure that withstands pressure and vibration.
- Corrosion Resistance: 304 stainless steel (UNS S30400) provides excellent resistance to acidic and alkaline food media.
- Customizable Dimensions: While standard length is 2m, diameter, end connections (threaded/flanged), and slot width can be tailored to your process.
- Easy Cleaning: Smooth surface and open design facilitate CIP (Clean-in-Place) procedures, reducing labor and chemical use.

The 0.3mm slot is particularly effective for removing fine particles such as fruit pulp, yeast, starch granules, and other solids, ensuring product clarity and quality. Our wedge wire Johnson filter is manufactured with precision winding and welding techniques, resulting in a uniform slot opening that remains stable even under high flow rates. The 304 stainless steel grade offers good weldability and formability, making it suitable for both new installations and retrofitting into existing systems.
Advantages for your food processing line:
- Reduced maintenance frequency due to self-cleaning wedge wire profile.
- Improved product yield by minimizing loss of valuable solids.
- Compliance with food safety standards (material is FDA-compliant upon request).
- Long service life even in abrasive or corrosive environments.
- Quick delivery and flexible customization to match your specific equipment.

Frequently Asked Questions
-
Q: What is the maximum operating temperature for this 304 stainless steel filter?
A: 304 stainless steel can generally withstand temperatures up to 870°C (1600°F) in intermittent service and 925°C (1700°F) in continuous service. However, for food processing, typical operating temperatures are below 100°C. Please confirm your specific temperature range for optimal performance. -
Q: Can the slot width be customized to a different size?
A: Yes, slot widths from 0.1mm to 10mm are available. The 0.3mm slot is a standard option, but we can produce custom widths according to your filtration requirements. -
Q: Is this filter suitable for CIP (Clean-in-Place) systems?
A: Absolutely. The smooth wedge wire surface and open structure allow effective cleaning with CIP chemicals and high-pressure water, reducing downtime and labor. -
Q: What end connections are available?
A: We offer threaded (NPT/BSP), flanged (ANSI/DIN), or plain ends. The connection type can be customized based on your piping system. -
Q: How do I determine the correct outer diameter for my application?
A: The outer diameter depends on flow rate, vessel size, and pressure drop. Common diameters range from 50mm to 300mm. Contact our technical team with your process parameters, and we can recommend the optimal size. -
Q: Does the filter come with any certification for food contact?
A: The 304 stainless steel material is compliant with FDA food contact standards. We can provide material certificates upon request. However, we do not claim third-party certifications unless explicitly verified. -
Q: What is the minimum order quantity (MOQ) for this product?
A: MOQ is typically 10 pieces for standard sizes. For custom orders, MOQ may vary. Please contact our sales team for specific details. -
