Established in 1998, Anping County Boli Hardware Wiremesh Products Factory has been a trusted manufacturer of industrial filtration solutions for over two decades. Our Industrial Spin-down Filter 200 Micron 2 inch Flanged 316 Stainless Steel 150 PSI represents the essence of our engineering expertise — combining durable materials, precise filtration, and easy maintenance to serve our global clients across North America, South America, Europe, Asia, and beyond. Designed for demanding environments, this filter delivers reliable performance in water treatment, irrigation, and process systems, helping you protect downstream equipment and reduce downtime.
The spin-down filter features a unique centrifugal action that separates solid particles from the fluid stream, allowing for continuous filtration without frequent cartridge replacement. With a robust 316 stainless steel body and flanged connections, it withstands high pressure and corrosive conditions, making it ideal for both industrial and commercial applications. Its 200-micron stainless steel mesh screen captures sand, rust, scale, and other particulates, while the flush valve enables quick cleaning without disassembly, ensuring minimal operational interruption.
Key Features & Technical Specifications
- Material: Premium 316 stainless steel housing and screen — excellent corrosion resistance, suitable for saltwater and chemical exposure.
- Filtration Grade: 200 micron (approx. 74 mesh) — effectively removes medium-sized particles while maintaining high flow rate.
- Connection: 2-inch ASME/ANSI flanged inlet and outlet — easy integration into existing piping systems.
- Pressure Rating: 150 PSI (10.3 bar) maximum working pressure — safe for moderate to high-pressure lines.
- Temperature Range: -20°C to 100°C (optional high-temperature version available upon request).
- Flush Valve: 1/2" NPT bottom drain with manual ball valve — quick purge without stopping flow.
- Sealing: EPDM O-rings (NBR or Viton optional) — leak-proof and chemical resistant.
- Installation: Vertical orientation recommended; supplied with mounting bracket.

Frequently Asked Questions
-
Q: What is the difference between a spin-down filter and a standard Y-type strainer?
A: A spin-down filter uses centrifugal force to separate solids from the fluid, allowing continuous operation even when the screen is partially loaded. The flush valve can be opened to discharge debris without stopping the flow. Y-type strainers typically require manual disassembly for cleaning. -
Q: Can this filter be used for seawater or brackish water?
A: Yes, the 316 stainless steel construction provides excellent resistance to chloride corrosion, making it suitable for seawater, brackish water, and other corrosive fluids. However, we recommend advising us of your specific water chemistry to select the optimal O-ring material (Viton recommended for high salinity). -
Q: How often should I flush the filter?
A: Flushing frequency depends on the contaminant load. For typical well water with moderate sand content, flushing every 1–2 weeks is sufficient. For heavy sediment, daily or weekly flushing may be needed. The built-in manual ball valve makes the process quick and easy. -
Q: What is the maximum operating temperature?
A> The standard version is rated for -20°C to 100°C. If you require higher temperatures (up to 150°C), we can supply high-temperature Viton seals. Please specify when ordering. -
Q: Does the filter come with a pressure gauge or drain valve?
A: The standard model includes a 1/2" NPT drain valve with a manual ball valve. Pressure gauges are not included but can be added as an optional accessory. We also offer threaded connections for gauge installation. -
Q: Can I use this filter for gas or air filtration?
A: While designed for liquid filtration, it can be used for low-pressure gas or air with solid contaminants. However, the pressure drop and flow characteristics may differ. For compressed air systems, we recommend our dedicated coalescing filters. -
Q: What certifications does your factory hold?
A: As a manufacturer with over 25 years of experience, we follow strict internal quality control procedures. We can provide material test certificates (MTC) for 316 stainless steel upon request. For specific certifications required by your market, please contact our sales team for feasibility. -
Q: What is the lead time and shipping cost?
A: Lead time is typically 15–25 working days depending on quantity. We ship via sea, air, or express from ports such as Tianjin, Qingdao, Shanghai, and Foshan. Exact shipping costs depend on destination and order volume — please contact us for a quote.
