Frequently Asked Questions:
Q1: What is the difference between a scraper filter element and a standard Johnson screen?
A scraper filter element is designed with a flat or curved surface that allows easy cleaning by scraping, while standard Johnson screens are typically used for static filtration. The scraper design is ideal for applications where periodic cleaning is required.
Q2: Can I customize the slot width and length?
Yes, we offer customization for slot width (from 0.1mm to 10mm) and length according to your specifications. Minimum order quantity may apply.
Q3: Is 304 stainless steel suitable for seawater applications?
304 grade offers good corrosion resistance in freshwater and mild environments. For seawater, we recommend 316L or duplex stainless steel. Please consult our engineers for the best choice.
Q4: What is the maximum working pressure for this filter element?
The standard rating is 1.6MPa. Higher pressure ratings up to 5MPa are available upon request, with reinforced design.
Q5: How do I clean the filter element?
Backwashing with water or air, or manual scraping, is effective. The wedge wire design prevents particles from getting trapped, making cleaning easier.
Q6: What is the typical lead time?
For standard sizes, lead time is 15-20 days. Custom orders may take 25-30 days depending on quantity and complexity.
Q7: Do you provide samples?
Yes, we can provide samples of small size for evaluation. Sample cost is negotiable, and shipping is borne by the customer.
Q8: What certifications do you have?
Our products are manufactured in compliance with international standards. We can provide material test reports and dimensional certificates upon request. Specific certifications are available subject to customer requirements.
