Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer established in 1998, proudly presents our Conical Filter Element — a high-performance filtration solution designed for demanding industrial applications. With an annual export value exceeding US$5 million and shipments to over 15 global markets, our factory combines decades of wire mesh expertise with precision engineering. Each conical filter element comes with a 1-year warranty, a Mill Test Report, and undergoes 100% pressure testing to ensure unmatched reliability. Whether you need to separate solids from liquids, protect downstream equipment, or achieve consistent filtration quality, our conical elements deliver superior performance and long service life.
Our conical filter elements are manufactured from high-grade stainless steel (304, 316L) or carbon steel, with customizable mesh sizes ranging from 0.5 to 500 microns. The conical (tapered) design offers several advantages over flat or cylindrical filters: it provides a larger surface area for efficient filtration, reduces clogging, and allows for easy backwashing or cleaning. Each element is fabricated using advanced welding techniques and then subjected to a 100% hydraulic pressure test to verify structural integrity. A detailed Mill Test Report accompanies every order, documenting material composition, mesh count, and pressure test results, giving you complete traceability and quality assurance.

The conical shape of our filter element offers distinct advantages: increased dirt-holding capacity, reduced pressure drop, and self-cleaning characteristics during backwash. This design is especially effective in high-viscosity fluids or applications with high solid loading. The 100% pressure test ensures that every element can withstand your system’s operating conditions without failure. The included Mill Test Report provides full material traceability, essential for industries with strict quality requirements such as pharmaceutical or food processing.

Frequently Asked Questions
-
Q: What materials are available for the conical filter element?
A: We offer stainless steel (304, 316L), carbon steel, and other alloys upon request. The material can be customized based on your fluid compatibility and temperature requirements. -
Q: How is the filtration rating defined?
A: The filtration rating is based on the mesh count. For example, a 100-mesh screen captures particles larger than approximately 150 microns. We can provide elements from 0.5 micron (sintered mesh) up to 500 micron (perforated plate). -
Q: Do you provide samples before bulk order?
A: Yes, we can produce samples for evaluation. Sample cost and shipping are negotiable, and we can deduct the sample cost from the first mass production order. -
Q: What is the lead time for custom conical filter elements?
A: Typical lead time is 15–25 working days after receipt of deposit and approved drawing. For urgent orders, expedited production can be arranged. -
Q: How is the 100% pressure test performed?
A: Each element is hydrostatically tested at 1.5 times its design pressure. The test pressure is held for a specified duration to ensure no leaks or deformation. A test certificate is included in the Mill Test Report. -
Q: Can the conical filter element be used for backwashing?
A: Yes, the conical shape promotes efficient backwashing. The tapered design allows solids to be easily flushed out during reverse flow, reducing maintenance downtime. -
Q: What is the warranty coverage?
A: We offer a 1-year warranty against manufacturing defects in materials and workmanship. This covers issues such as mesh detachment, weld failure, or corrosion under normal operating conditions. -
Q: Do you export to my country?
A: We export to North America, South America, Europe, Asia, Africa, Oceania, and the Middle East. We have experience with international shipping and can handle customs documentation. Please contact us with your destination port for a freight quote.
