Frequently Asked Questions
-
Q: What is the difference between a Johnson filter and a regular wedge wire screen?
A: A Johnson filter (or scraper filter element) is specifically designed for use in scraper-type filtration systems, featuring a continuous slot that allows easy cleaning with a scraper. It is optimized for high-efficiency solid-liquid separation. -
Q: Can the slot width be customized to other sizes?
A: Yes, we offer customization for slot widths from 0.05mm to 5mm. Please provide your required filtration precision and we will produce accordingly. -
Q: Is this filter element suitable for high-temperature environments?
A: 304 stainless steel can withstand operating temperatures up to approximately 400°C in air, but the actual limit depends on the specific application (e.g., corrosive media). For higher temperatures, 316L or other alloys are available upon request. -
Q: How do I clean the filter element?
A: The wedge wire design minimizes clogging. For routine cleaning, backwashing or mechanical scraping is effective. For stubborn deposits, chemical cleaning or ultrasonic cleaning can be used. -
