At Anping County Boli Hardware Wiremesh Products Factory (established 1998, with annual export value of US$5-10 million), we take pride in engineering high-performance filtration solutions. Our 304 Stainless Steel, 100μm, Automatic Backwash, 1.0MPa Self-cleaning Filter Element is specifically designed for photovoltaic cutting fluid applications. This innovative filter element ensures continuous operation without manual cleaning, reducing downtime and maintenance costs while maintaining consistent filtration quality. Built with premium 304 stainless steel, it offers excellent corrosion resistance even in harsh cutting fluid environments.
The self-cleaning mechanism activates automatically when differential pressure reaches a preset level, using reverse flow to flush captured particles from the filter surface. This process takes only seconds and does not interrupt the main flow, making it ideal for high-demand manufacturing lines where every minute of uptime counts. With a working pressure rating of 1.0 MPa and precision filtration down to 100 microns, it effectively removes silicon carbide, diamond grit, and other abrasive particles from photovoltaic cutting fluids, protecting downstream equipment and improving wafer quality.

Why choose our self-cleaning filter element for photovoltaic cutting fluid? The photovoltaic industry demands extremely clean cutting fluids to prevent wafer scratching and ensure high yields. Our filter element removes abrasive particles continuously, maintaining fluid clarity without operator intervention. The 304 stainless steel construction resists corrosion from water-based cutting fluids and glycol-based coolants, providing reliable performance over thousands of operating hours. The automatic backwash system uses only a small portion of the filtered fluid (typically 1–3% of total flow) to clean the element, minimizing waste and energy consumption.
Integration and installation: The filter element can be installed in-line with minimal piping modifications. It supports both horizontal and vertical mounting orientations. The control unit (optional) can be configured for remote monitoring and alarm output. Our engineering team provides installation guidance and technical support to ensure seamless integration into existing photovoltaic cutting fluid recycling systems.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between automatic backwash and manual backwash?
A: Automatic backwash uses a control system (differential pressure switch or timer) to initiate the cleaning cycle without human intervention. Manual backwash requires an operator to open a valve or start a process. Our filter element is fully automatic, reducing labor and ensuring consistent cleaning. -
Q: Can this filter element handle high-viscosity cutting fluids?
A: Yes, it is designed for typical photovoltaic cutting fluids (water-based, glycol-based). For very high viscosity fluids, we recommend consulting our engineering team for customized flow path design. -
Q: How often does the backwash cycle occur?
A: The frequency depends on the contaminant load. Typically, the filter backwashes every 1–4 hours under normal conditions. The differential pressure trigger can be set between 0.05–0.5 MPa, and the timer can be adjusted from 10 minutes to 24 hours. -
Q: Is 304 stainless steel suitable for cutting fluids with high chloride content?
A: For fluids with chloride levels above 200 ppm, we recommend considering 316L stainless steel. Our standard 304 grade is suitable for most photovoltaic cutting fluids. Please provide your fluid analysis for material recommendation. -
Q: What is the lifespan of the filter element?
A: With proper operation, the 304 stainless steel filter element can last 5–10 years. The woven wire mesh is durable and resistant to wear. Regular visual inspection is recommended every 6 months. -
Q: Can I get a custom connection size or thread type?
A: Yes, we offer customization. Common connections include ANSI flanges, DIN flanges, BSP threads, NPT threads, and tri-clamp. Please specify your requirements. -
Q: Does the filter element require any power source?
A: The automatic backwash mechanism requires a small electric actuator or pneumatic valve (power supply 24V DC or 110/220V AC). Alternatively, a purely hydraulic version is available for sites without electricity. -
Q: What is the minimum order quantity?
A: For standard models, MOQ is 1 piece. For custom designs, MOQ may vary. Contact us for details.
