Frequently Asked Questions (FAQ)
-
Q: What is the difference between a wedge filter and a wire mesh filter?
A: A wedge filter uses continuous V-shaped wires wound on support rods, creating a self-cleaning slot that resists clogging. Traditional wire mesh filters have a woven structure that can trap particles more easily, requiring more frequent cleaning. Wedge filters are ideal for high-flow, high-solid applications. -
Q: Can the slot size be customized for different filtration requirements?
A: Yes, we offer slot sizes from 0.05mm to 10mm or more. The 0.1mm slot is standard for fine water filtration, but we can adjust based on your specific particle size needs. -
Q: Is this filter suitable for seawater or aggressive chemicals?
A: Standard 304 stainless steel is suitable for fresh water, mildly acidic or alkaline conditions. For seawater or high chloride environments, we recommend 316L stainless steel option, which is available upon request. -
Q: How do I clean the wedge filter?
A: The filter can be cleaned by backwashing with water or air, or by using a brush. The V-shaped slot design allows trapped particles to be easily dislodged. For heavy solids, chemical cleaning or ultrasonic cleaning may be used – consult our technical team. -
Q: What end connections do you offer?
A: We provide threaded connections (NPT/BSP), flanged ends (ANSI/DIN), or plain ends for welding. Custom end caps and adapters are also available. Please specify your requirements. -
Q: Do you provide samples for testing?
A: Yes, we can provide small samples (e.g., 100mm long) for evaluation. Sample cost and shipping are negotiable. Contact our sales team for details. -
Q: What is the typical lead time for bulk orders?
A: For standard sizes, lead time is 15–25 days after deposit. Customized orders may require 25–35 days. We work with reliable logistics to ensure on-time delivery. -
Q: Is the filter supplied with a quality certificate?
A: Yes, each batch comes with a material test certificate (MTC) and inspection report. We can also provide ISO compliance documentation upon request.
