Category: Bag Filters
Series: MB
Model format: `[MEDIA]-[MICRON]-[SIZE]-[FLANGE]-[OPTIONS]`
Example: `POMO-5-2-PS`

## Overview
Mono/multifilament mesh bags for industrial liquids in standard housings provide high-flow, low-dP surface filtration; sewn construction with molded collars or rings, silicone-free, with nylon/polyester options suitable for food contact

## How It Works
Surface filtration through woven mesh: particles larger than the mesh openings are retained on the surface during inside-to-outside flow in a sealed housing. Monofilament provides precise, uniform openings with low fiber migration; multifilament offers economical screening.

## Applications
- Water and wastewater prefilters; intake/pump protection; membrane pretreatment
- Chemical batch screening of hard particles; raw material cleanup
- Paints, inks, coatings where silicone‑free materials are required
- Oils, fuels, produced water; coolants and metalworking fluids
- Pulp and paper, power, and general process liquids; marine/desal pre‑RO
