## Overview
Pleated cellulose fiber filter elements designed for dry gas filtration applications. The pleated design maximizes filtration area, offering benefits such as reduced downtime, extended meter life, and improved measurement accuracy.

## How It Works
Gas flows through pleated cellulose fiber media. The pleated design maximizes surface area for filtration, allowing for efficient capture of particulates while maintaining low pressure drop.

## Applications
- Industrial/process gas lines and instrument air prefiltration
- Prefiltration ahead of coalescers or fine polishers
- Removal of dirt, pipe scale and foreign matter from gas streams
- Protection of downstream equipment and meters
