Frequently Asked Questions
1. What is the difference between a wedge filter and a wire mesh filter?
Wedge filters use V-shaped wires wound on support rods, creating a continuous slot that is less prone to clogging and provides higher strength compared to woven wire mesh. They are ideal for high-flow and backwashing applications.
2. Can I get a sample before bulk order?
Yes, samples are available. Please contact us with your required slot size, shape, and dimensions. We can produce a small sample for evaluation.
3. What is the minimum order quantity (MOQ)?
MOQ depends on the size and complexity. For standard sizes, MOQ is typically 10 pieces. For custom designs, please inquire.
4. How long does delivery take?
Typical lead time is 15–25 working days after order confirmation, depending on quantity and customization. Express delivery is available for urgent orders.
5. Do you provide the mill test report for every batch?
Yes, a mill test report is included with each shipment, verifying material grade (304 stainless steel) and mechanical properties.
6. Can the wedge filter be used for high-temperature applications?
Yes, 304 stainless steel can withstand up to 400°C (752°F). For higher temperatures, we can offer 310S or other heat-resistant alloys.
7. What payment terms do you accept?
We accept T/T, L/C, D/P, and Western Union. Terms are negotiable for long-term partners.
8. How do I clean the wedge filter?
Backwashing is the most common method. The non-clogging slot design makes cleaning efficient. Chemical cleaning or high-pressure water jet can also be used.
