Anping County Boli Hardware Wiremesh Products Factory, established in 1998, is a professional manufacturer specializing in filtration solutions. Our Prefiltration Unit for Hydraulic Oil Systems is designed to extend the service life of downstream components by removing contaminants at an early stage. With a 10 μm beta rating and 210 bar working pressure, this unit ensures reliable protection even under demanding conditions. Whether you are upgrading an existing system or building a new one, our prefiltration unit delivers consistent performance and cost-effective maintenance.
This prefiltration unit is engineered to capture particles down to 10 microns with a high beta ratio (β≥200), meaning it effectively removes 99.5% of particles of that size. It is built to withstand a maximum working pressure of 210 bar, making it suitable for high-pressure hydraulic circuits commonly found in mobile equipment, industrial machinery, and power generation systems. The compact design allows easy integration into existing piping layouts.
Key Features & Technical Specifications
- High Efficiency Filtration: Beta rating ≥200 at 10 μm ensures high dirt holding capacity and low pressure drop.
- Robust Construction: Housing made from carbon steel or stainless steel (optional) with corrosion-resistant coating.
- Flexible Connection: Available with SAE flanges, NPT threads, or BSP threads to match your system.
- Easy Maintenance: Replaceable filter element with quick-change design minimizes downtime.
- Wide Temperature Range: Suitable for operating temperatures from -20°C to +80°C.
- Compact Footprint: Space-saving design fits into tight installations.

Benefits for Your Hydraulic System:
By installing this prefiltration unit upstream of sensitive components such as pumps, valves, and motors, you significantly reduce wear and tear. The 10 μm filtration captures both abrasive particles and soft contaminants, preventing premature failure and extending oil change intervals. With a high dirt holding capacity, the element lasts longer, reducing replacement frequency and operational costs. The 210 bar rating ensures you can rely on the unit even in high-pressure circuits typical of injection molding machines, presses, and construction equipment.
Quality Assurance & Trust:
Anping County Boli Hardware Wiremesh Products Factory has been a trusted manufacturer since 1998. With annual export value exceeding US$5 million and shipments to major ports including Tianjin, Qingdao, Shanghai, and Foshan, we serve customers across North America, South America, Europe, Southeast Asia, and more. Our prefiltration units undergo rigorous testing to ensure consistent performance and compliance with international standards. Each unit is individually pressure-tested before shipment. We are confident that our product will meet your expectations for reliability and efficiency.

Frequently Asked Questions (FAQ)
Q1: What is the beta rating and why is it important?
A: Beta rating (β) indicates the filtration efficiency. For example, β≥200 at 10 μm means the filter captures at least 99.5% of particles ≥10 μm. Higher beta values mean better protection for your hydraulic system.
Q2: Can this unit be used with other fluids besides hydraulic oil?
A: While designed for hydraulic oils, it can be used with compatible lubricating oils and fluids. Please consult our technical team for specific compatibility data.
Q3: What is the maximum flow rate this unit can handle?
A: The maximum flow rate depends on the viscosity of the fluid and the pressure drop allowed. Typical flow rates range from 50 to 200 L/min. Please contact us with your system parameters for a precise recommendation.
Q4: How often should the filter element be replaced?
A: Replacement intervals depend on the contamination level of your system. We recommend monitoring the differential pressure indicator (if installed) and replacing the element when pressure drop reaches a certain level, typically 1.5-2 bar.
Q5: Are mounting brackets included?
A: Mounting brackets are available as an optional accessory. The standard unit is designed for inline installation with pipe clamps or custom supports.
Q6: Is there a bypass valve in the filter head?
A: Yes, an integral bypass valve opens at a preset pressure to protect the element in case of clogging or cold start. The bypass setting is typically 3-5 bar, but can be customized upon request.
Q7: What certifications does your factory hold?
A: Our factory operates under a quality management system and can provide test reports. For specific certifications required by your region, please inform us so we can discuss compliance options.
Q8: Can I get a sample before placing a bulk order?
A: Yes, sample orders are welcome. We can provide a single unit for testing. Please note that sample shipping costs may apply.
