Frequently Asked Questions
Q1: What is the exact opening size of a 20 mesh filter disc?
A: 20 mesh means 20 openings per inch, resulting in an opening size of approximately 850 microns (0.033 inch). The exact opening may vary slightly depending on wire diameter, but our standard 0.3mm wire yields consistent openings.
Q2: Can I get discs with a different thickness or mesh count?
A: Yes, we offer customization. You can choose other mesh sizes (e.g., 10, 40, 100 mesh) and thicknesses (0.2mm, 0.5mm, etc.). Minimum order quantity may apply for custom specifications.
Q3: Are these discs suitable for high-temperature filtration?
A: 304 stainless steel can withstand temperatures up to 800°C in oxidizing environments. For continuous use above 500°C, we recommend using 316L stainless steel or other alloys.
Q4: What edge finishing options are available?
A: We offer plain cut edges, welded ring edges, folded edges, or encapsulated edges for better sealing. Please specify your requirement when ordering.
Q5: Do you provide samples before bulk order?
A: Yes, we can supply samples of standard sizes. Sample cost is negotiable, and shipping is at your expense. Contact our sales team for details.
Q6: How do you ensure the quality of these filter discs?
A: Every production batch is inspected for mesh count, wire diameter, disc diameter, and edge finish. We use precision measuring tools and follow internal quality control procedures. Random samples are retained for traceability.
Q7: What is the typical lead time for an order?
A: For standard sizes, lead time is 7–15 working days. For custom orders, please allow 15–25 working days, depending on quantity and complexity.
Q8: Can these discs be used for corrosive liquids?
A: 304 stainless steel offers good resistance to many chemicals, but for highly corrosive media (e.g., strong acids, chlorides), we recommend 316L or Hastelloy. Please consult our technical team for material selection.
