Frequently Asked Questions (FAQ)
Q1: What is the difference between a Johnson wedge filter and a conventional wire mesh filter?
A: Johnson wedge filters use a continuous V-shaped wire wound around a support structure, creating a precise slot that is resistant to clogging and easy to backwash. Conventional mesh filters have a woven structure that can trap particles and may require more frequent cleaning.
Q2: Can this filter be used for high-temperature applications?
A: 304 stainless steel can withstand temperatures up to about 870°C in continuous service, but the working temperature should be verified based on your specific process conditions. For higher temperatures, 316L or other alloys are available upon request.
Q3: What is the maximum flow rate for a 1000mm ID filter?
A: Flow rate depends on slot opening, length, and operating pressure. As a reference, a 1000mm ID filter with 0.1mm slots can handle several hundred cubic meters per hour under 12 bar pressure. Please provide your process parameters for a precise calculation.
Q4: Do you offer custom slot sizes or lengths?
A: Yes, we can customize slot openings from 0.05mm to 3mm and lengths up to 6000mm. Inner diameters from 20mm to 2000mm are available. Contact our sales team with your requirements.
Q5: How is the filter cleaned and maintained?
A: The V-shaped slot design allows for effective backwashing or chemical cleaning. Regular inspection and backwashing will maintain performance. Full dismantling is rarely needed due to the anti-clogging profile.
Q6: What certifications do your products have?
A: Our manufacturing process follows ISO 9001 quality management standards. Specific certifications (e.g., CE, WRAS) can be applied upon request based on your target market.
Q7: What is the typical lead time for this filter?
A: For standard sizes, lead time is 15–20 working days. Custom orders may require 25–30 days depending on complexity. We can expedite urgent orders.
Q8: Can you provide samples for testing?
A: Yes, sample orders are welcome. We can manufacture a small filter segment for performance evaluation. Please contact us for sample pricing and shipping details.
