Leading Plastic Filter Housings Manufacturer China
Plastic filter housings are essential for corrosive liquid filtration, offering a strong alternative to stainless steel in chemical, wastewater, and high-purity applications. The right material choice directly impacts lifespan, safety, and operating cost—so selection matters.
Differences Between Materials
| مادة | Strength | Chemical Resistance | Temperature | Cost | Best Use |
|---|---|---|---|---|---|
| PP | Medium | Moderate | ≤70°C | Low | General filtration |
| PPH | Medium+ | Good | ≤80°C | Low–Med | Chemical liquids |
| FRP | High | Very Good | ≤120°C | Medium | Industrial heavy-duty |
| PVDF | High | Excellent | ≤120°C | High | High purity & aggressive fluids |
Bag vs Cartridge Housing
| Feature | غلاف مرشح الكيس | Cartridge Filter Housing |
|---|---|---|
| Flow Rate | High | Medium–High |
| Filtration Precision | 1–2000 µm | 0.1–100 µm |
| Cost | Lower | Higher |
| Replacement | Easy | Moderate |
| Best Use | Bulk filtration | Fine filtration |
