Precision filtration is critical to ensuring product purity, protecting equipment, and optimizing industrial processes. Our industrial Liquid Filter Bags are engineered to meet these demanding requirements across a vast array of applications. They serve as a highly efficient, reliable, and cost-effective solution for solid-liquid separation in systems ranging from machine tool coolant loops to food and beverage production lines and water treatment plants.

Key Features & Design Excellence

Advanced Sealing Technology: Our bags feature stainless steel or galvanized steel rings manufactured with precise argon arc welding. This results in an extremely low diameter error (<0.5mm) and horizontal error (<0.2mm), which significantly improves the seal within your filter housing, virtually eliminating side leakage and bypass.
Clean Manufacturing Process: The bags are produced on high-speed industrial sewing machines that operate without silicone oil cooling. This critical detail prevents silicone oil contamination of your filtrate, ensuring fluid purity—a paramount concern in food, pharmaceutical, and high-precision industries.
Comprehensive Material Selection: Choose from three primary filter media, each with distinct properties:

Polypropylene (PP)
Excellent chemical resistance, especially to strong acids and alkalis. Ideal for chemical processing and plating solutions.

Polyester (PE)
Good all-around chemical resistance and higher temperature tolerance. Suitable for a wide range of industrial liquids.

Nylon (PA)
Excellent abrasion resistance and alkali resistance. Perfect for applications involving wear or alkaline fluids.
Wide Filtration Spectrum: Achieve your desired clarity with micron ratings ranging from fine 0.5 microns for polishing to 600 microns or more for coarse particle removal. The specific available ratings vary by material to match performance characteristics.
User-Oriented Design: We use easily removable labels to prevent ink or label material from contaminating your product during use.

Frequently Asked Questions

What makes your filter bags less prone to side leakage?

Our key innovation is the ultra-precise metal ring. Manufactured with argon arc welding to tolerances below 0.5mm, it creates a near-perfect seal against the filter housing gasket, drastically reducing the gap that causes side leakage.

I'm concerned about filter media introducing contaminants. How is this addressed?

We address this in two ways: 1) Our sewing machines do not use silicone oil, eliminating that source of fluid contamination. 2) Product labels are designed to be easily removable to prevent label or ink from entering your filtrate.

Which filter bag material is best for filtering a strong acidic solution?

Polypropylene (PP) is the unequivocal best choice for strong acids, as it offers "Excellent" resistance to both strong acids and alkalis according to our chemical resistance chart.

Do you offer custom sizes outside your five standard models?

Yes, we fully support customization (OEM). You can request filter bags in virtually any dimension, micron rating, and material combination to fit your unique filter housing and process requirements.

What industries are these liquid filter bags commonly used in?

They are incredibly versatile and are widely used in Food & Beverage (beer, wine, juices), Water Treatment, Machine Tool Coolant Filtration, Chemical Processing, Pharmaceuticals (ultra-pure water), Oil & Gas, and Marine systems.
