Welcome to Anping County Boli Hardware Wiremesh Products Factory – your trusted partner for industrial filtration solutions since 1998. Our Stainless Steel Spiral Filter Tube is engineered to deliver exceptional oil filtration efficiency in demanding industrial systems. With decades of expertise in wire mesh manufacturing and a global export footprint, we provide a product that combines durability, precision, and cost-effectiveness. Whether you need to remove particulate contaminants from hydraulic oils, lubricants, or fuel, this filter tube is designed to extend equipment life and reduce downtime.
The spiral construction of our filter tube creates a large filtration surface area, enabling high dirt-holding capacity and consistent flow rates. Made from premium stainless steel, it resists corrosion, high temperatures, and pressure fluctuations, making it ideal for continuous operation in harsh environments. Below, we detail the key features and specifications that set this product apart.
Key Features & Benefits
- High Filtration Efficiency: The spiral design ensures uniform particle capture, achieving up to 99% removal efficiency for particles down to 5 microns.
- Durable Stainless Steel Construction: Available in 304 or 316L stainless steel, offering excellent resistance to rust, chemicals, and thermal stress.
- Customizable Dimensions: We offer tailored diameters (20–200 mm), lengths (100–2000 mm), and connection types to fit your existing system.
- Easy Maintenance & Long Service Life: The robust structure allows for repeated cleaning (backwashing or ultrasonic) without deformation, reducing replacement costs.
- Wide Application Range: Suitable for oil filtration in hydraulic systems, lubricating oil circuits, fuel filtration, and industrial process fluids.
- Enhanced Flow Characteristics: The spiral channels minimize pressure drop while maximizing throughput, optimizing system efficiency.

Our Stainless Steel Spiral Filter Tube is manufactured using advanced CNC winding technology, ensuring consistent spiral pitch and uniform filtration performance. The tube can be designed with either single-layer or multi-layer mesh, depending on the required filtration level and mechanical strength. For viscous oil applications, we recommend a larger spiral pitch to prevent clogging, while fine filtration tasks benefit from a tighter wound structure.
One of the key advantages of this product is its recyclability. Unlike disposable filter cartridges, our stainless steel spiral tube can be cleaned and reused multiple times, significantly reducing operational waste and long-term costs. It is also compatible with automatic backwashing systems, making it an excellent choice for continuous filtration processes.

Frequently Asked Questions (FAQ)
Q1: What is the typical lifespan of the stainless steel spiral filter tube?
A: The lifespan depends on operating conditions and maintenance. With proper cleaning (backwashing or ultrasonic), the tube can last several years. The stainless steel construction resists corrosion and fatigue, making it a long-term investment.
Q2: Can I use this filter tube for water filtration as well?
A: Yes, while designed for oil filtration, the spiral filter tube is also suitable for water, chemicals, and other industrial fluids. Please specify the fluid type and temperature when ordering for optimal material selection.
Q3: How do I clean the filter tube?
A: Common cleaning methods include backwashing with clean oil or solvent, ultrasonic cleaning, or high-pressure water jet. The spiral structure allows easy access to trapped particles. Avoid using abrasive tools that may damage the mesh.
Q4: What filtration accuracy do you recommend for hydraulic oil systems?
A: For hydraulic oil, we typically recommend 10–25 microns, depending on the system's tolerance. For high-precision systems, 5–10 microns is common. We can provide testing samples to verify performance.
Q5: Do you offer custom sizes and connection types?
A: Absolutely. We can customize outer diameter, length, spiral pitch, and connection type (threaded, flanged, etc.). Please provide your system drawings or dimensional requirements for a tailored solution.
Q6: What is the minimum order quantity (MOQ)?
A: Our MOQ is typically 10 pieces for standard sizes. For custom orders, the MOQ may vary based on complexity. We also offer sample orders for evaluation.
Q7: How do you ensure product quality?
A: We have a multi-step quality control process: incoming material inspection, in-process dimensional checks, visual inspection, pressure test, and final filtration efficiency test. Each batch is traceable.
Q8: Can you provide a certificate of material or origin?
A: Yes, we can provide a material test certificate (MTC) and certificate of origin upon request. Please mention this requirement when placing an order.
