Reliable Coarse-to-Fine Particle Protection for Strainer Applications

Skytech Ultrafab Strainer Filter Bags provide reliable coarse-to-fine particle removal in pump strainers, pipeline basket strainers, and inline filtration assemblies across industrial water systems, cooling towers, HVAC, chemical dosing, and agricultural irrigation. Available in woven polypropylene, nylon, stainless steel mesh, and needle-felt media from 50 µm to 5000 µm (5 mm), these bags protect downstream equipment from damage and fouling.

What Are Strainer Filter Bags?

Strainer filter bags are coarse filtration elements inserted into basket strainer bodies fitted to pipelines, pump inlets, and process equipment. Unlike fine liquid filter bags that capture sub-micron particles, strainer bags are designed for the first line of protection — removing large-particle debris, scale, rust, grit, and solids from process streams before they can damage pumps, valves, heat exchangers, and downstream process equipment.

Features and Benefits

• Wide Micron Range: Available from 50 µm woven mesh through 5000 µm (5 mm) aperture for first-stage coarse straining in all pipeline and pump strainer configurations
• Multiple Material Options: Woven nylon, PP monofilament, stainless steel wire mesh, and needle-felt options cover the full range of chemical compatibility and temperature requirements
• Heavy-Duty Ring Construction: Rigid polypropylene, stainless steel, or galvanised steel retaining rings ensure a positive seal in strainer pot bodies and prevent bag bypass under high flow rates
• Reinforced Bottom: Double-stitched or welded bottom closure prevents bag blowout under surge pressure conditions at pump start-up
• Custom Strainer Fit: Bags manufactured to exact internal diameter and depth of standard and custom strainer pot bodies — ensuring secure fitment and positive sealing rim contact
• Easy Maintenance: Bags quickly removed, cleaned, and reinstalled during planned maintenance shutdowns — or replaced with fresh bags during emergency strainer cleaning operations

Technical Specifications

Applications
