Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer since 1998 with an annual export value of US$5-10 million, proudly introduces our Threaded Connection, 1/2" NPT, 100μm Self-cleaning Filter Element designed specifically for PV cutting fluid. This filter element combines precision filtration with automatic cleaning technology, reducing downtime and maintenance costs while ensuring consistent fluid quality. Our decades of experience in wire mesh manufacturing guarantee a robust, reliable product that meets the demanding requirements of photovoltaic production lines.
The filter element features a 1/2-inch NPT threaded connection for easy integration into existing piping systems. The 100-micron filtration precision effectively removes particles such as silicon powder, quartz sand, and metal debris from the cutting fluid, protecting downstream equipment and extending fluid life. The self-cleaning mechanism operates automatically based on pressure differential or timer, flushing contaminants out without interrupting the filtration process.
Key Features
- Self-cleaning design – Automatically removes trapped particles, minimizing manual cleaning and replacement.
- 1/2" NPT threaded connection – Compatible with standard pipe fittings, quick and secure installation.
- 100μm filtration precision – Balances high flow rate with effective particle removal.
- Durable stainless steel construction – Resists corrosion from cutting fluids, long service life.
- Low maintenance – Only periodic inspection required; no disposable filter cartridges.
- Customizable parameters – Available in different materials, connection sizes, and filtration ratings upon request.

Applications & Benefits
This filter element is specifically engineered for PV cutting fluid (silicon carbide slurry) used in wire sawing of silicon wafers. It effectively removes large particles that could cause scratches or damage to wafers. The self-cleaning function ensures continuous operation, reducing the need for frequent filter changes and minimizing fluid waste. By maintaining fluid cleanliness, it helps improve cutting efficiency and yield.
Benefits to customers:
- Reduced operational costs – No disposable filter cartridges, lower labor costs for cleaning.
- Increased uptime – Automatic backwashing keeps production running without interruption.
- Extended fluid life – Cleaner fluid reduces bacterial growth and chemical degradation.
- Improved product quality – Consistent filtration prevents defects in wafers.
- Eco-friendly – Less waste from filter media and fluid disposal.

Frequently Asked Questions
- Q: How does the self-cleaning mechanism work? A: The filter element uses an automatic backwash system. When the pressure differential across the filter reaches a preset level (or at a timed interval), a valve opens to reverse flow through the filter media, flushing captured particles out through a drain port. The process takes only a few seconds and does not require stopping the main flow.
- Q: Can this filter element be used with other fluids besides PV cutting fluid? A: Yes, it is suitable for various industrial fluids with similar viscosity and particle characteristics, such as coolant, hydraulic oil, or water with suspended solids. Please consult with our team for compatibility.
- Q: What is the expected lifespan of the filter element? A: The stainless steel filter media is durable and can last for years under normal operation, as the self-cleaning prevents clogging. The lifespan depends on the fluid conditions and the frequency of backwashing, but typically it exceeds 2-3 years.
- Q: Is the 1/2" NPT connection standard? Can I get other sizes? A: The standard connection is 1/2" NPT female thread. We can also provide other sizes (e.g., 3/4", 1") or thread types (BSP, metric) as custom options.
- Q: Do you provide samples for testing? A: Yes, we offer sample orders for evaluation. Please contact our sales team to discuss the sample policy and shipping.
- Q: What is the backwash water consumption? A: Each backwash cycle consumes a small amount of fluid (typically 50-100 ml), which can be collected and reused if desired. The volume depends on the filter design and can be adjusted.
- Q: How do I install the filter element? A: The filter element has a threaded port that connects directly to a standard 1/2" NPT pipe. It should be installed in a vertical or horizontal orientation with the drain port at the bottom. Detailed installation instructions are provided with each unit.
- Q: Can the filtration precision be customized? A: Yes, we can manufacture filter elements with different micron ratings (e.g., 50 μm, 200 μm) to suit your specific filtration needs. Please contact us with your requirements.
