Frequently Asked Questions
-
What is the difference between a wedge wire filter and a Johnson screen?
They are essentially the same product. “Johnson screen” is a brand name that became a generic term for wedge wire screens used in well screens and industrial filters. Our wedge filter uses the same continuous V-wire winding technology. -
Can I use this filter for drinking water?
Yes, 304 stainless steel is food-grade and safe for potable water applications. We can also provide electropolished surface finish for enhanced hygiene. -
What slot size should I choose for my application?
It depends on your particle size and flow rate. Our technical support team can recommend the optimal slot size based on your specific requirements. Common ranges: 0.2–0.5mm for fine filtration, 1–5mm for coarse screening. -
How do I clean the filter?
Backwashing is the most effective method. The V-shaped slot design allows particles to be easily flushed out. For severe fouling, chemical cleaning or ultrasonic cleaning can be used. -
What is the maximum pressure this filter can withstand?
Pressure rating depends on diameter, wall thickness, and support structure. Typically, our filters handle up to 10 bar (150 psi) for standard designs. For high-pressure applications, we can reinforce the inner support. -
Do you offer samples before bulk order?
Yes, we provide sample filters for testing. Sample cost is reasonable, and we can deduct it from your first bulk order. Contact our sales team for details. -
How long is the replacement guarantee?
We offer a free replacement guarantee for manufacturing defects within 12 months from the date of shipment. Technical support is available for the entire service life of the product. -
Can you customize the connection type?
Absolutely. We can weld threaded couplings, flanges (ANSI, DIN, JIS), or provide plain ends for welding. Just let us know your system requirements.
