## Overview
TG elements are pleated-media cartridges for particulate removal in gas streams. Large surface area pleats deliver low initial dP and long life while protecting downstream coalescers and equipment.

## How It Works
Gas flows outside-to-inside across tightly spaced pleats. The pleated surface area holds a growing particulate cake on the upstream side; as the cake forms it contributes to fine capture and stabilizes efficiency. FX version features a keyed interface between the housing riser and inner cartridge top cap to keep the element concentric, prevent sag under liquid load, and maintain a tight gasket-to-cup seal to eliminate bypass.

## Applications
- Dry gas transmission, processing and storage
- Compressor suction/discharge
- Gas gathering
- Metering / custody transfer
- Glycol and amine contactor protection
- Fuel gas
- Utility & instrument air
- Removal of fine, rigid solids such as dust, rust, scale, sand, salts, coal fines and other particulates
