Bag filter housing plays a crucial role in industrial liquid filtration, ensuring efficient removal of contaminants. The design of bag filter directly impacts filtration efficiency, making it essential to choose the right bag filter housing for your application.
In this blog, we will explore the key factors in the design of bag filter, how to improve efficiency, and tips for selecting the best bag filter housing for your needs.
1. Understanding Bag Filter Housing and Its Importance
A bag filter housing is a pressure vessel that holds filter bags to trap impurities from liquid streams. The design of bag filter determines how effectively it removes contaminants, improves process efficiency, and extends equipment life. Selecting the right bag filter housing ensures reliable filtration performance.
2. Key Factors in the Design of Bag Filter
The design of bag filter affects its efficiency and suitability for various industrial applications. Here are the essential factors to consider:
a) Filtration Capacity & Flow Rate
- The design of bag filter should match the required flow rate (liters per minute or GPM).
- A properly designed bag filter housing prevents clogging and pressure drop, ensuring high efficiency.
- Multi-bag housings improve efficiency for high-volume filtration.
b) Material Selection for Bag Filter Housing
The design of bag filter depends on the material used in the bag filter housing, which should be compatible with the liquid being filtered:
- Stainless Steel (SS 304/316) – Ideal for high-temperature and corrosive applications.
- Carbon Steel – Suitable for general industrial use.
- Polypropylene/PVC – Best for low-pressure, non-corrosive filtration.
c) Micron Rating & Filtration Efficiency
- The efficiency of bag filter housing depends on selecting the correct micron rating.
- Fine filtration: 1–10 microns for high-purity applications.
- Coarse filtration: 50–200 microns for larger contaminants.
- The design of bag filter should prevent particle bypass to maintain efficiency.
d) Pressure & Temperature Ratings
- A durable bag filter housing must withstand system pressure and temperature requirements.
- High-pressure processes require reinforced bag filter housing for maximum efficiency.
- Corrosive applications need chemical-resistant bag filter housing materials.
e) Housing Design & Sealing Mechanism
- A well-sealed bag filter housing prevents leakage and ensures high efficiency.
- The design of bag filter should include a top-entry system for better sealing.
- Swing bolt or clamp closures make bag filter housing maintenance easier.
f) Ease of Maintenance & Filter Bag Replacement
- Quick-opening bag filter housing reduces downtime.
- Basket strainers in bag filter housing support filter bags for easy removal.
- The design of bag filter should allow easy replacement to maintain efficiency.
g) Compliance with Industry Standards
- A high-quality bag filter housing should meet industry standards like ISO, ASME, and FDA.
- The design of bag filter must follow regulatory guidelines for safety and efficiency.
3. How to Improve the Efficiency of Bag Filter Housing
The efficiency of a bag filter housing depends on proper selection, installation, and maintenance. Follow these tips to maximize efficiency:
✅ Choose the right micron rating based on contaminants.
✅ Ensure proper sealing in the bag filter housing to avoid leaks.
✅ Use a multi-bag filter housing for high-flow applications.
