How Filter Bags Work
Liquid enters the filter housing and flows into the filter bag.
Particles are trapped either:
- Inside the depth layers (PP/PE), or
- On the surface (mesh/PTFE/metal)
Clean liquid exits, while contaminants remain inside the bag.
Differences Between Filter Bag Types
| 유형 | 여과 유형 | 내열성 | Reusability | Cost | Best For |
|---|---|---|---|---|---|
| PP | 깊이 | 낮음~중간 | No | Low | Water, chemicals |
| PE | 깊이 | 중간 | Limited | 낮음~중간 | Food, pharma |
| PTFE | 표면 | Very High | Yes | 높은 | Corrosive fluids |
| Nylon (NMO) | Surface (mesh) | 중간 | Yes | 중간 | Precise filtration |
| 스테인리스 스틸 | 표면 | Very High | Yes | 높은 | High-temp, oi |
Common Types of Filter Bags
1. PP (Polypropylene) Filter Bags
- Best for general-purpose filtration
- Excellent chemical resistance (acids & alkalis)
- Cost-effective and widely used
2. PE (Polyester) Filter Bags
- Stronger than PP with better abrasion resistance
- Good for higher temperature applications
- Ideal for fine particle filtration
3. PTFE Filter Bags
- Premium material for extreme conditions
- مقاunt to strong chemicals and high temperatures
- Used in corrosive and high-purity processes
4. Nylon (NMO) Mesh Filter Bags
- Monofilament mesh for precise filtration
- Reusable and easy to clean
- High flow, low pressure drop
5. Stainless Steel Filter Bags
- Fully reusable and durable
- Withstand high pressure and temperature
- Suitable for harsh industrial environments

Selection Tips (From Real Projects)
- High dirt load? → Choose PP depth filter bags
- Need precision? → Use nylon mesh (NMO)
- High temperature or aggressive chemicals? → Go with PTFE
- Want long-term reuse? → Stainless steel is best
- Food/pharma? → Ensure FDA compliance
자주 묻는 질문
1. What is the difference between PP and PE filter bags?
PP has better chemical resistance, PE has better strength.
2. Are filter bags reusable?
Mesh and metal bags are reusable; PP/PE are usually disposable.
3. 어떤 미크론 등급을 선택해야 합니까?
Depends on particle size and downstream equipment needs.
4. How often should filter bags be replaced?
When pressure drop increases or flow rate decreases.
5. Can filter bags be customized?
Yes, fully customizable in size, material, and micron rating.
