Eaton Industrial Nylon Mesh Filter Bags: Precision Liquid Filtration

Precision Surface Filtration for Industrial Applications

At Purecowater, we specialize in high-performance filtration solutions for complex industrial challenges. Among the most versatile and reliable options in our inventory are Eaton Industrial Nylon Mesh Filter Bags. These bags are the industry standard for surface filtration applications requiring precision, strength, and reusability.

Designed for applications where maintaining specific pore sizes is critical, Eaton’s Nylon Monofilament (NMO) bags provide a fixed-aperture structure that effectively sieves particles from liquids. Unlike needlefelt bags that rely on depth filtration, nylon mesh bags maximize surface retention, making them ideal for removing solid particulates from paints, solvents, water, and other process fluids.

What Are Nylon Mesh Filter Bags?

Eaton’s Nylon Mesh bags are constructed from woven monofilament fibers. “Monofilament” means that each thread is a single, continuous filament, much like a fishing line. When woven into a mesh, these filaments create uniform square openings. This construction offers distinct advantages over multifilament or felt media:

• Absolute Efficiency: The fixed woven structure prevents pore shifting under pressure, ensuring consistent particle removal at the rated micron size.
• Non-Fiber Releasing: Because the material is a continuous filament, there are no loose fibers to migrate into the filtrate, making it safe for high-purity paints and coatings.
• High Strength: Nylon is known for its excellent tensile strength and resistance to abrasion.
• Cleanability: The smooth surface allows for the bags to be washed and reused in many non-critical applications, reducing consumable costs.

Key Features and Technologies

Eaton integrates advanced sealing technologies into their filter bags to prevent fluid bypass—a common issue in lower-quality filtration systems.

Feature	Benefit
SNAP-RING® Seal	A classic metal or plastic ring sewn into the top of the bag creates a tight seal within the housing basket, preventing bypass.
SENTINEL® Seal Ring	An all-plastic, pressure-activated sealing ring that chemically bonds to the bag body. As pressure increases, the seal tightens, ensuring 100% bypass-free filtration.
Material Compatibility	Nylon provides excellent resistance to solvents, alkalis, and oils at higher temperatures.

Technical Specifications

Choosing the right filter bag requires understanding the operating conditions. The Eaton NMO series covers a wide range of micron ratings to suit everything from coarse straining to fine polishing.

Max Operating Temperature	Up to 325°F (163°C) depending on ring selection
Chemical Resistance	Excellent for Solvents (Aromatic/Aliphatic), Esters, Ketones, Alkalies. Note: Generally poor resistance to strong acids.
Bag Sizes	#01 (7″ x 17″), #02 (7″ x 32″), #03 (4″ x 9″), #04 (4″ x 15″)

Common Applications

Because nylon mesh is silicone-free and non-migrating, it is a preferred choice in industries where surface finish quality is paramount.

• Automotive & Paint: Filtration of primers, topcoats, and clear coats to remove agglomerates without affecting pigments.
• Chemical Processing: Filtering solvents and resins where polypropylene bags might swell or degrade.
• Water Treatment: Removal of sand, algae, and grit from well water or process cooling water.
• Metal Working: Straining drawing compounds and hydraulic oils.
• Food & Beverage: (Specific FDA-compliant grades available) Filtering edible oils and viscous syrups.
