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
| Материал | Strength | Химическая стойкость | Temperature | Стоимость | Наилучшее применение |
|---|---|---|---|---|---|
| ПП | Средний | Умеренный | ≤70°C | Низкий | General filtration |
| PPH | Medium+ | Хорошо | ≤80°C | Low–Med | Chemical liquids |
| FRP | Высокий | Very Good | ≤120°C | Средний | Industrial heavy-duty |
| PVDF | Высокий | Отлично | ≤120°C | Высокий | High purity & aggressive fluids |
Bag vs Cartridge Housing
| Функция | Корпус рукавного фильтра | Cartridge Filter Housing |
|---|---|---|
| Расход | Высокий | Medium–High |
| Filtration Precision | 1–2000 µm | 0.1–100 µm |
| Стоимость | Lower | Higher |
| Replacement | Easy | Умеренный |
| Наилучшее применение | Bulk filtration | Fine filtration |
