For operations requiring robust pre‑filtration of large particulates—such as resin beads, pulp fragments, paint chips, or sediment—our Size #1, 800 Micron – Nylon Monofilament Mesh Liquid Filter Bag, Plastic “P” Flange Ring delivers the perfect blend of high flow, dependable capture, and user‑friendly design.

Size #1, 800 Micron - Nylon Monofilament Mesh Liquid Filter Bag w/Plastic Ring (NMO800P1P)

1. Optimized Coarse Filtration at 800 Microns

  • Effective Bulk Solids Removal
    At an 800 µm rating, this filter bag intercepts the bulk of suspended solids before they damage pumps, clog fine filters, or foul membranes.

  • High Throughput
    Precision‑woven monofilament mesh provides over 70 % open area, enabling flow rates up to 35 GPM per bag with minimal pressure drop.

  • Layered Filtration Strategy
    Use as the first stage ahead of 200 µm or 100 µm bags to extend the service life of downstream finer elements.

2. Durable, User‑Friendly Construction

Nylon Monofilament Mesh

  • Uniform 800 µm Pores: Single‑strand weave maintains consistent retention without fiber shedding.

  • High Strength & Chemical Resistance: Nylon PA66 endures temperatures up to 300 °F and tolerates mild acids, alkalis, oils, and common solvents.

  • Long Service Life: Robust fibers resist tearing under pulsating flows or sudden pressure surges.

Plastic “P” Flange Ring

  • Snap‑Fit Seal: Molded polypropylene flange locks securely into standard Size #1 housings (7.06″ ID), preventing bypass.

  • Corrosion‑Free: All‑plastic construction eliminates rust and metal contamination risks.

  • Quick Change‑Out: Lip design allows fast removal and replacement without tools.

3. Versatile Applications

  1. Water & Wastewater Screening: Remove sand, grit, and organic debris at intake before main treatment.

  2. Chemical & Resin Processes: Trap large resin beads and slurry particles to protect pumps and valves.

  3. Paints, Coatings & Inks: Filter out pigment agglomerates to ensure smooth application.

  4. Food & Beverage Pre‑Straining: Clarify raw juice or brewing mash by removing coarse solids.

  5. Coolant & Lubricant Filtration: Capture metal swarf and chips in machining operations.

  6. Aquaculture & Aquarium: Intercept fish feed and waste to maintain water quality.

5. Installation & Maintenance Best Practices

  • Secure Seating: Snap the plastic “P” flange firmly into the housing ledge for a leak‑proof fit.

  • Support Cage: Always install a Size #1 support basket to maintain bag shape and prevent creasing.

  • ΔP Monitoring: Use pressure gauges upstream and downstream; change the bag at ~12 psi differential.

  • Cleaning & Reuse: Rinse nylon mesh with low‑pressure water or mild detergent; allow to dry completely before reinstalling.

  • Spare Rotation: Keep at least two spare bags on hand per housing to avoid process interruptions.
