Frequently Asked Questions (FAQ)
-
Q: What is the difference between a Johnson screen and a regular wire mesh filter?
A: A Johnson screen uses V-shaped wedge wire wound around support rods, creating continuous slots that are less prone to clogging and easier to clean. It offers higher strength and precise filtration compared to woven mesh. -
Q: Is 304 stainless steel safe for food contact?
A: Yes, 304 stainless steel is widely used in food processing equipment due to its corrosion resistance, non-reactivity, and ease of sanitization. It meets international food-grade standards. -
Q: Can the slot width be customized for different particle sizes?
A: Absolutely. We offer slot widths from 0.1mm to 3mm, and we can produce even finer or coarser slots upon request. Tolerance is maintained within ±0.02mm. -
Q: How do I clean the filter during operation?
A: The wedge wire design supports backwashing and CIP (Clean-in-Place). The smooth surface and self-cleaning slot geometry minimize fouling, reducing downtime. -
Q: What end connections are available?
A: Common options include flanges (DIN, ANSI, JIS), threaded ends, welding ends, and tri-clamp connections for sanitary applications. We can adapt to your existing piping. -
Q: Do you provide samples for testing?
A: Yes, we offer sample filters for testing. Please contact our sales team with your requirements. Sample cost is negotiable, and shipping is via your preferred carrier. -
Q: What is the typical lead time for custom orders?
A: For standard sizes, lead time is 10-15 working days. Custom orders with special dimensions or connections may require 20-25 working days, depending on quantity. -
Q: Can the filter be used in high-temperature applications?
A: Yes, 304 stainless steel can operate up to 400°C. For higher temperatures, we can supply 316L or other alloy materials upon request.
