I. Pre-Filters (Security Filters)
Filter bags are cost-effective for pre-filtration. High-flow pleated filter cartridges made with 25μm membrane rated as 5μm provide excellent pre-filtration performance. When selecting pre-filters, consider the following factors:
- Particle size distribution in the feed stream
- Flow rate requirements
- Pressure drop limitations
- Chemical compatibility with process fluids
II. Cartridge Filter Selection Criteria
When selecting filter cartridges, consider these key parameters:
| Parameter | Consideration |
|---|---|
| Micron Rating | Select based on required filtrate quality |
| Flow Rate | Ensure cartridge can handle system flow |
| Pressure Rating | Must exceed maximum operating pressure |
| Chemical Compatibility | Media must resist process fluid |
| Temperature Range | Must accommodate operating temperature |
| End Cap Style | Must match housing configuration |
III. Housing Material Selection
Filter housings are available in various materials including 304 stainless steel, 316 stainless steel, and carbon steel with coating. Material selection depends on process fluid compatibility, operating pressure, and environmental conditions.
