Applications & Advantages
Our wedge filters are widely used in municipal water filtration, industrial wastewater treatment, oil and gas well screens, food processing (e.g., juice extraction), and chemical filtration. The continuous slot construction provides high open area, enabling efficient flow while retaining fine particles. The lack of a woven mesh eliminates blind spots and reduces maintenance costs. Compared to perforated screens, wedge wire filters offer higher strength and longer service life under abrasive conditions.
Frequently Asked Questions (FAQ)
-
Q: What is the difference between a wedge filter and a conventional mesh screen?
A: Wedge filters use V-shaped wire profiles wound around support rods, creating a continuous slot that prevents clogging and allows easy backwashing. Mesh screens are woven and can trap particles in the weave, leading to blinding. -
Q: Can I get a custom slot size other than 0.5mm?
A: Yes, we offer slot sizes from 0.1mm to 10mm depending on your filtration requirements. Please contact us with your specific needs. -
Q: Is the Mill Test Report always provided?
A: Yes, every filter we ship includes a Mill Test Report that certifies the material grade, chemical composition, and mechanical properties. -
Q: What is the typical lead time for this product?
A: For standard 1.5m length and 0.5mm slot, lead time is approximately 15–20 working days after order confirmation. Custom orders may require additional time. -
Q: Can these filters be used for high-temperature applications?
A: Yes, stainless steel 316L can withstand temperatures up to 400°C. For higher temperatures, we can recommend other materials upon request. -
Q: How is the filter cleaned?
A: The wedge design allows for effective backwashing, chemical cleaning, or mechanical brushing. Detailed instructions are available upon request. -
Q: Do you offer samples for testing?
A: Yes, we can provide sample lengths for evaluation. Please contact our sales team to arrange. -
Q: What packaging is used for export?
A: Filters are packed in wooden crates or strong cartons with foam padding to prevent damage during transit, suitable for ocean or air freight.
