Custom Filtration Solutions (CFS) — ESP Extended Surface Pleat Liquid Bag Filter

Overview

The CFS ESP Extended Surface Pleat liquid filter bag is designed for high dirt-holding capacity and longer on-stream life. Under normal operating conditions, ESP bags can provide approximately four times the service life of a standard nominal felt bag, reducing change-outs and downtime while increasing throughput. Unique internal pleats use two layers of pleated felt to maximize usable media area.

Key Features

~4× life of a standard nominal bag (typical, under normal operating conditions).
Unique internal pleats with two layers of pleated felt for high dirt loading.
Wide chemical compatibility with polypropylene and polyester media choices.
Media options meet FDA food-contact requirements (CFR 21 §177.1520).
Silicone-free construction.
Choice of steel ring or plastic flange connections.
Handles on all ring-style bags (standard).

Typical Uses

General liquid filtration where longer life and fewer change-outs are desired.
Applications benefiting from wide chemical compatibility of PP/PET felts.
Processes requiring silicone-free construction.
Food-contact compliant applications (per CFR 21 §177.1520).

Notes

Service life and dirt-holding capacity depend on process conditions and contaminant profile.
Select ring or flange style to match your housing design and sealing requirements.
