Product Advantages & Client Benefits
Our 20-micron scraper filter element offers distinct advantages over traditional mesh or perforated screens. The wedge wire construction provides a rigid, self-supporting structure that resists deformation under pressure. The smooth, continuous slot surface prevents particle entrapment, allowing easy backwashing and reducing chemical cleaning needs. This translates to lower operating costs, less downtime, and consistent filtration performance over extended periods.
For industrial clients, this filter element is particularly beneficial in applications where fine solids removal is critical, such as in cooling water systems, process water recycling, or chemical injection lines. The scraper action ensures that even sticky or fibrous materials are dislodged, maintaining high flow rates. Additionally, the 304 stainless steel material is compatible with most neutral and mildly acidic fluids, offering broad chemical resistance.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between a Johnson filter and a traditional mesh filter?
A: A Johnson filter uses a wedge wire profile with V-shaped slots that provide a scraper effect, preventing clogging and allowing self-cleaning. Mesh filters are prone to blinding and require more frequent cleaning. -
Q: Can this filter element be used for high-temperature applications?
A: Yes, the 304 stainless steel material can withstand temperatures up to 400°C, depending on the design. Please specify your temperature requirements when ordering. -
Q: How do I clean the scraper filter element?
A: The element can be cleaned by backwashing or using a scraper mechanism. The wedge wire design allows easy dislodging of solids. For heavy fouling, chemical cleaning may be used with compatible solvents. -
Q: What is the typical lifespan of this filter element?
A: Lifespan depends on operating conditions, but with proper maintenance, a 304 stainless steel Johnson filter can last several years. Its robust construction resists wear and corrosion. -
Q: Do you offer custom sizes or end connections?
A: Absolutely. We can customize length, diameter, slot width, and connection types (threaded, flanged, etc.) to fit your existing equipment. Please provide your specifications. -
Q: Is this filter element suitable for food and beverage applications?
A: 304 stainless steel is food-grade and suitable for many food and beverage processes. However, we recommend verifying compatibility with specific fluids or regulations. -
Q: What is your minimum order quantity (MOQ)?
A: Our MOQ is typically 10 pieces for standard sizes, but we can accommodate smaller orders for samples or prototypes. Contact us for details. -
Q: How do I ensure the filter element fits my housing?
A: Provide us with the inner diameter, length, and connection type of your housing. We’ll manufacture accordingly. A drawing or reference model is helpful.
