The customized stainless steel bag filter housing is a high-performance, pressure-rated filtration vessel engineered for industrial liquid filtration applications where high flow rates, large dirt-holding capacity, and operational efficiency are paramount. Constructed from premium-grade stainless steel (304 or 316L), this housing provides exceptional corrosion resistance, durability, and reliability—making it the preferred choice for facilities that demand consistent fluid purity and minimal downtime.
What sets this housing apart is its full customization capability. From bag size (#1, #2, #3, or #4) and connection types to pressure ratings, seal materials, and surface finishes—each unit can be tailored to match your exact system specifications.

The customized stainless steel bag filter housing is widely used across diverse industries due to its dependability and adaptability:
Q1: What is the difference between a bag filter housing and a cartridge filter housing?
A: Both serve the same basic purpose—holding filtration media to remove contaminants from liquids—but they are designed for different applications.
Bag Filter Housing is the better choice when:
Your liquid has high solids loading or looks “dirty”
You have high flow rates (a single #2 bag can handle 100-150+ GPM)
You need to change filters quickly and minimize downtime
You want lower initial and operating costs
Cartridge Filter Housing is the better choice when:
You need fine filtration down to 0.1 microns
You are “polishing” a liquid for pharmaceutical, fine chemical, or beverage applications
Filtration precision is more important than flow volume
Q2: What is the difference between SS304 and SS316L for bag filter housings?
A: SS304 contains 18% chromium and 8% nickel. It offers excellent corrosion and oxidation resistance at a cost-effective price point. It is suitable for general water treatment, food processing (non-acidic), and standard industrial applications.
SS316L contains 10% nickel, 2% molybdenum, and 16% chromium. The molybdenum provides superior resistance to chlorides, saltwater, acids, and aggressive chemicals. The “L” stands for low carbon, which improves weldability and resistance to intergranular corrosion.
Recommendation: Choose SS316L for applications involving chlorides above 200 ppm, saltwater exposure, CIP washing with caustic or acidic sanitizers, or pharmaceutical and food-grade requirements. Choose SS304 for general industrial water, light chemical duties, and less corrosive environments.
Q3: What are the standard sizes of bag filter housings?
A: Standard bag sizes are typically:
| Bag Size | Diameter | Length |
|---|---|---|
| Size 1 | 7″ (180 mm) | 16″ (410 mm) |
| Size 2 | 7″ (180 mm) | 32″ (810 mm) |
| Size 3 | 4″ (100 mm) | 8″ (200 mm) |
| Size 4 | 4″ (100 mm) | 14″ (350 mm) |
Size 2 is the most commonly used for industrial applications due to its high flow capacity and large dirt-holding capacity. Custom sizes are also available upon request.
Q4: How do I select the right bag filter housing for my application?
A: Consider the following factors:
Flow rate requirements: Determine the volume of liquid you need to filter per hour. This will dictate whether you need a single-bag or multi-bag housing.
Operating pressure and temperature: Select a housing rated for your system’s conditions.
Chemical compatibility: Choose housing material (304 vs. 316L) and seal material (EPDM, Viton, PTFE, etc.) resistant to your process fluid.
Filtration accuracy: Determine the micron rating needed for your application.
Regulatory compliance: Ensure the housing meets relevant standards (PED, ASME, CE, etc.).
Space constraints: Consider the footprint and height of the housing in your facility.
