Frequently Asked Questions
-
Q: What is the difference between wedge wire screen and woven wire mesh?
A: Wedge wire screen uses V-shaped wires welded on support rods, creating a continuous slot that is self-cleaning and offers higher open area. Woven wire mesh has cross-woven wires, which can trap particles more easily and may clog faster. Wedge wire is preferred for high-flow, low-maintenance filtration. -
Q: Can I use this screen for high-temperature applications?
A: Yes, 304 stainless steel can operate up to 400°C (752°F) in continuous service. For higher temperatures, we offer 316L or other alloys upon request. -
Q: Is the screen FDA approved for direct food contact?
A: The material is 304 stainless steel compliant with FDA regulations (21 CFR 177.2600). The screen is manufactured under food-grade standards, making it safe for direct contact with food, beverages, and potable water. -
Q: What sizes and shapes are available?
A: We offer standard flat panels, cylinders, and cones. Custom dimensions, slot profiles, and support rod spacing are available. Please provide your drawing or specifications for a tailored solution. -
Q: How do I clean the screen?
A: The V-shaped slot design allows easy backwashing with water or air. For stubborn deposits, chemical cleaning or ultrasonic cleaning is possible. The smooth surface resists adhesion. -
Q: What is the minimum order quantity (MOQ)?
A: MOQ is typically 10 pieces for standard sizes. Custom orders may have different MOQs. Contact us for details. -
Q: Can you provide samples?
A: Yes, samples are available for evaluation. You can request a small piece of wedge wire screen to test in your process. Please cover shipping costs. -
