Frequently Asked Questions
-
Q: What is the difference between a wedge wire filter and a wire mesh filter?
A: A wedge wire filter uses V-shaped wires wound around support rods, creating continuous slot openings that are less prone to clogging. Wire mesh filters have woven openings which can trap particles more easily. Wedge filters are ideal for high-flow, heavy-duty applications where self-cleaning is required. -
Q: Can I customize the slot size and dimensions?
A: Yes, we offer full customization. You can specify slot opening from 0.1mm to 10mm, outer diameter, length, and end connections. Our team will help you select the optimal configuration for your process. -
Q: What is the typical lead time for factory-direct orders?
A: For standard sizes, lead time is 7–15 working days. Custom orders may take 15–25 working days depending on complexity. We can expedite rush orders upon request. -
Q: Do you provide technical support for installation?
A: Yes, our technical team can provide guidance on installation, backwash frequency, and maintenance. We also offer drawings and dimensional data for integration into your system. -
Q: Is this filter suitable for corrosive environments?
A: 304 stainless steel offers good resistance to many corrosive media. For aggressive chemicals or high chloride environments, we can supply 316L or duplex stainless steel variants upon request. -
Q: What is your warranty policy?
A: We provide a 12-month warranty against manufacturing defects. If any issue arises due to our workmanship, we will replace or repair the product at no cost. Warranty terms are clearly stated in the purchase contract. -
Q: How do I ensure the correct filter size for my application?
A: You can send us your process parameters (flow rate, particle size, pressure, temperature) and our engineers will recommend the appropriate slot size, diameter, and length. We can also provide free sample testing. -
Q: What are the shipping options and ports?
A: We ship from Tianjin, Qingdao, Shanghai, and Foshan ports. We support FOB, CIF, and EXW terms. For small quantities, we can arrange express delivery (DHL, FedEx, UPS).
