Frequently Asked Questions
-
Q: What is the difference between a Johnson type and a standard filter element?
A: The Johnson type features a continuous V-shaped wire profile, which provides a larger open area and is better suited for scraper applications. It also offers higher mechanical strength and resistance to clogging compared to conventional mesh filters. -
Q: Can you customize the micron rating to, say, 50 microns exactly?
A: Yes, we can produce filter elements with any micron rating between 20 and 100 microns per your request. For other ranges, please contact us for feasibility. -
Q: What is the maximum pressure this filter element can handle?
A: The pressure rating depends on the specific dimensions and end connections. Typically, our 304 stainless steel Johnson type elements can operate up to 10 bar (145 psi). For higher pressures, we can design reinforced versions. -
Q: Are these filter elements suitable for food-grade applications?
A: Yes, 304 stainless steel is food-grade material, and our surface finish is polished to meet hygiene standards. However, we recommend verifying with your local food safety regulations. -
Q: How do I install the scraper mechanism?
A: The filter element is designed to be used with a scraper system that moves along the outer surface. We provide installation guidelines and can supply custom adapters if needed. -
Q: What is the typical lead time for a custom order?
A: For standard sizes, lead time is 15–20 days. Customized orders may take 20–30 days depending on complexity and quantity. We expedite urgent orders upon request. -
Q: Do you provide samples for testing?
A: Yes, we offer sample orders. Please contact our sales team with your requirements. Sample cost is negotiable and will be deducted from future bulk orders. -
Q: Can you ship to my country via express or sea freight?
A: Absolutely. We ship from multiple ports (Tianjin, Qingdao, Shanghai, Foshan) and can arrange air, sea, or express delivery. We serve markets worldwide, including Europe, Americas, Middle East, and Asia.
