## Overview
Sintered metal cartridge engineered for harsh services where durability and reproducibility are critical

## How It Works
Fluid passes through a diffusion-bonded porous metal matrix that captures contaminants on its surface; accumulated solids are removed by backwash or chemical/steam cleaning to restore permeability

## Applications
- High-temp gas particulate filtration and CIP/SIP duty
- Corrosive chemical/solvent filtration (acid/caustic compatible)
- Steam filtration and sterilizing-grade gas service
- Hot oil and high-viscosity polymer/adhesive filtration
- Catalyst fines recovery and backwashable guards
- Abrasive seawater/desalination intake prefiltration
- Refinery/chemical plant high-pressure prefilters
