Welcome to Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer established in 1998 with over two decades of expertise in wire mesh and filtration solutions. Our Double Layer Detachable Stainless Steel Perforated Filter Tube is specifically designed for hot melt glue machines, offering superior filtration performance and easy maintenance. With an annual export value exceeding US$5 million, we serve global markets including North America, Europe, and Southeast Asia, ensuring consistent quality and reliable supply chains.
This filter tube is engineered to remove impurities from molten adhesive, preventing nozzle clogging and ensuring consistent glue application. The double-layer detachable design allows quick cleaning and replacement of inner or outer layers, reducing downtime and extending service life. Made from premium stainless steel (304 or 316L), the tube withstands high temperatures (up to 300°C) and corrosive environments typical in hot melt adhesive processes.
Key Features & Technical Specifications
- Double-Layer Structure: Inner perforated layer + outer support layer, detachable for thorough cleaning. The gap between layers can be customized to achieve desired filtration accuracy.
- Perforation Precision: Laser-cut round holes with staggered arrangement, available from 0.5mm to 2.0mm diameter. Custom hole patterns (slot, square, etc.) available upon request.
- High Temperature Resistance: Suitable for continuous operation up to 300°C (572°F), compatible with EVA, polyolefin, polyamide, and other hot melt adhesives.
- Corrosion Resistance: Stainless steel 304 or 316L ensures excellent durability in acidic or alkaline adhesive environments.
- Easy Detachment: Quick-release locking mechanism (screw type or bayonet) allows tool-free disassembly for cleaning or replacement.
- Customizable Dimensions: Outer diameter from 20mm to 200mm, length from 100mm to 2000mm, with threaded, flanged, or custom end connections.
- Surface Finish: Electropolished interior and exterior for smooth flow, reduced adhesive buildup, and easy cleaning.

Advantages & Customer Benefits
- Reduced Downtime: The detachable double-layer design allows separate cleaning of each layer without removing the entire tube from the machine. This cuts maintenance time by up to 50% compared to traditional single-layer filters.
- Enhanced Filtration Efficiency: The dual-layer system provides progressive filtration: the outer layer captures larger particles, while the inner layer traps finer contaminants. This prevents rapid clogging and extends the service interval.
- Cost Savings: Instead of replacing the entire filter element, you only need to replace the damaged inner layer. The outer layer often remains reusable, reducing replacement costs.
- Improved Product Quality: Clean adhesive means fewer nozzle blockages, consistent glue bead size, and reduced rejection rates in packaging, bookbinding, and woodworking applications.
- Versatile Compatibility: Fits most hot melt glue machine brands and models, including Nordson, ITW, Robatech, and Meltblown. Custom end connections ensure seamless integration.
- Long Service Life: Stainless steel construction resists wear and thermal shock, typically lasting 3-5 times longer than plastic or brass filters in similar applications.

Frequently Asked Questions
Q1: What is the difference between double-layer and single-layer filter tubes?
A: Double-layer tubes provide progressive filtration, longer intervals between cleaning, and the ability to replace only the inner layer. Single-layer tubes require full replacement when clogged, leading to higher cost and downtime.
Q2: Can this filter tube be used for other adhesive types besides hot melt?
A: Yes, it is suitable for any low to medium viscosity fluid that requires filtration, such as silicone, resin, or thermoplastic adhesives, provided the temperature and chemical compatibility are checked.
Q3: How do I clean the double-layer filter tube?
A: Disconnect the tube from the machine, unlock the detachable layers, and soak them in a suitable solvent (e.g., mineral spirits or hot water) to remove adhesive residue. Rinse and dry before reassembly.
Q4: What is the typical lifespan of this filter tube?
A: With regular cleaning, the stainless steel tube can last several years. The inner layer may need replacement every 6-12 months depending on adhesive quality and usage frequency.
Q5: Do you offer custom sizes or connections?
A: Absolutely. We can customize diameter, length, perforation pattern, and end connections (threaded, flanged, quick-connect) to match your machine. Please provide a drawing or sample.
Q6: Can you ship samples for testing?
A: Yes, we offer sample orders. The cost is reasonable, and we can ship via express or air freight. Please contact our sales team for details.
Q7: What is the minimum order quantity (MOQ)?
A: Our MOQ for standard sizes is 50 pieces. For custom designs, it may be 100 pieces. However, we accept smaller trial orders for new customers.
Q8: How do I ensure the tube fits my hot melt glue machine?
A: Please measure the existing filter housing dimensions (inner diameter, length, and connection type). We can also work with a photo or drawing of your current filter to provide a precise match.
