Category: Bag Filters
Series: PEPT
Model format: `PEPT-[MEDIA]-[MICRON]-[SIZE]-[FLANGE]`
Example: `PEPT-SL-3-2-PS`

## Overview
Nominal-rated phenolic-infused polyester felt bags use a non-compressible depth matrix for gels/high-vis fluids; the optional double layer adds area and slows dP rise, with a positive-seal flange/disc bottom for standard P1/P2 baskets

## How It Works
Inside-to-outside flow through a basket-supported bag. Phenolic-infused, non-compressible PET felt provides gradient-depth capture.

## Applications
- High-viscosity and gel-laden fluids: adhesives, sealants, coatings, inks
- Resins/polymers: epoxies, urethanes, acrylics, alkyds
- Petroleum/heavy liquids: asphalt, crude, lube/hydraulic oils, waxes/greases
- Process/water-based streams: antifreeze, cooling-tower water, completion fluids, saline
- Other: animal oils, elastomers, plasticizers, glycerine, turpentine, tung/rapeseed oils, cosmolene
