Frequently Asked Questions

Q: What is the typical application for a 0.4mm slot filter?
A: It is commonly used in water well screens, oil and gas filtration, industrial process filtration, and as a probe filter for instrumentation. The 0.4mm slot is suitable for retaining particles down to 0.4mm while allowing high flow rates.
Q: Can I get a custom length or end connection?
A: Yes, we offer fully customizable lengths from 100mm to 6000mm, and end connections can be threaded (NPT/BSP), flanged, or plain cut. Please provide your requirements.
Q: Is the test report included with every order?
A: Yes, each filter is inspected and comes with a standard test report that verifies slot size, outer diameter, and mechanical strength. Additional testing (e.g., pressure test) can be arranged upon request.
Q: What stainless steel grades are available?
A: Typically we offer SS304 and SS316L. SS316L provides better corrosion resistance in chloride environments. Other grades like duplex stainless steel are available on request.
Q: How does the wedge wire design prevent clogging?
A: The V-shaped profile creates a continuous slot that widens inward, allowing particles to pass through without becoming trapped. This self-cleaning feature reduces maintenance and extends service life.
Q: What is the maximum operating temperature and pressure?
A: For SS304, continuous up to 400°C (750°F); pressure rating depends on length and support structure. Typically, standard filters can withstand up to 10 bar. Please contact us for specific ratings.
Q: What is the lead time for a standard order?
A: For standard sizes (25mm OD, 0.4mm slot, 1-meter length), lead time is 7-10 working days. Custom orders may require 15-20 working days depending on complexity.
Q: Do you offer samples for testing?
A: Yes, we provide sample filters (usually 150mm length) at a nominal cost, with shipping charges. The sample fee is refundable upon bulk order placement.
