Stainless Steel Bag Filter

Our stainless steel bag filteris a high-performance industrial filtration device engineered for reliable solid-liquid separation across diverse harsh operating environments. Crafted from premium food-grade and industrial-grade SS304/316L stainless steel, this filter features a robust housing structure, matched with high-quality filter bags and a sturdy support basket, designed to deliver consistent, efficient filtration for both low and high flow rate applications. It adopts a user-friendly top-entry/side-entry design, supporting single-bag and multi-bag configurations to meet varied industrial filtration demands, from general liquid purification to high-precision contaminant removal. This filter stands as a cost-effective, durable filtration solution for manufacturers, processors, and industrial facilities seeking long-term, low-maintenance filtration performance.

Technical Features

Premium Stainless Steel Construction: Built with food-safe SS304 and corrosion-resistant SS316L stainless steel, the filter housing resists rust, chemical erosion, and high-temperature fluctuations, ensuring stable performance in acidic, alkaline, and high-humidity environments; SS316L is specially optimized for chloride-rich, marine, and chemical processing settings.

Leak-Proof Sealing System: Equipped with a 360° full-pressure seal and double O-ring sealing structure, it eliminates side leakage and cross-contamination between unfiltered and filtered liquids, guaranteeing nearly 100% sealing efficiency and pure filtration output.

Flexible Configuration & Wide Flow Compatibility: Supports single-bag (for small to medium flow) and multi-bag (up to 24 bags, for large flow up to 4400gpm/960m³/h) setups, with customizable inlet/outlet connections and adjustable mounting legs to fit diverse installation spaces and pipeline layouts.

High Filtration Precision & Large Dirt-Holding Capacity: Compatible with standard filter bags of 0.5–200 micron ratings, delivering high-precision contaminant removal while accommodating high solid loads to reduce frequent filter bag replacements; the streamlined internal structure minimizes pressure loss and ensures uniform flow distribution.

Quick Maintenance & Easy Operation: Features a quick-open top cover and detachable support basket, enabling tool-free filter bag replacement and simple cleaning; no complex disassembly is required, cutting down maintenance downtime and labor costs significantly.

Core Advantages

Unlike ordinary plastic or carbon steel filters, our stainless steel bag filter offers unparalleled durability and operational value for industrial users. First, its corrosion-resistant stainless steel body extends service life by 3–5 times compared to standard filters, reducing replacement frequency and long-term capital investment. Second, it delivers high filtration efficiency with low energy consumption, thanks to minimal pressure drop and large dirt-holding capacity, lowering daily operating costs and boosting production continuity. Third, it boasts strong material compatibility, suitable for filtering water, oils, chemicals, food liquids, and more, eliminating the need for multiple specialized filters and simplifying workflow. Fourth, it supports OEM customization, including tailored sizes, pressure ratings, and surface finishes, to match unique industrial process requirements. Finally, it complies with international industrial hygiene and safety standards, making it ideal for hygienic-sensitive industries like food, beverage, and pharmaceuticals.

Application Areas

This stainless steel bag filter is widely applied across key industrial sectors requiring reliable liquid filtration, covering both general and high-sanitary applications: Water Treatment (tap water purification, groundwater filtration, wastewater treatment, seawater desalination); Food & Beverage (edible oil, juice, dairy, wine, syrup filtration); Pharmaceutical & Biotechnology (raw material purification, finished product filtration, hygienic process liquid treatment); Chemical & Petrochemical (solvent filtration, oil refining, chemical intermediate purification, waste liquid treatment); Paint & Coating (ink, coating, pigment impurity removal); Electronics & Textiles (industrial water purification, electroplating liquid filtration); andMetallurgy & Machinery (cutting fluid, cooling water purification).

Frequently Asked Questions (FAQ)

1. Q: What micron ratings of filter bags are compatible with this stainless steel bag filter? 

A: Our filter supports standard filter bags ranging from 0.5 microns (high-precision fine filtration) to 200 microns (coarse impurity removal), and we can customize special micron ratings based on your specific filtration needs.

2. Q: How often should I replace the filter bag, and is replacement difficult?

A: Filter bag replacement frequency depends on liquid contamination level and operating hours (typically 1–4 weeks for heavy contamination, 1–3 months for light contamination). Replacement is extremely easy: just open the quick-release top cover, remove the old bag, and insert a new one—no tools or professional skills are needed, taking only 5–10 minutes.

3. Q: What’s the difference between SS304 and SS316L, and which should I choose?

A: SS304 is ideal for general industrial use (water, neutral liquids, mild environments) with cost-effective corrosion resistance; SS316L features superior chloride and acid resistance, perfect for chemical plants, coastal facilities, and acidic/alkaline liquid filtration. We recommend SS316L for harsh corrosive environments and SS304 for standard applications.

4. Q: Is this filter suitable for high-pressure industrial systems, and what‘s the maximum operating pressure? 

A: Yes, our stainless steel bag filter is designed for pressure-rated industrial systems, with a standard maximum operating pressure of 10 bar (145 psi); we can customize higher pressure ratings (up to 16 bar) for special high-pressure applications upon request.

5. Q: Do you offer custom sizes and after-sales support for this filter?

A: Absolutely. We provide full OEM customization, including custom flow rates, housing sizes, inlet/outlet types, and surface finishes. We also offer overseas online technical support, video guidance, and spare parts supply to ensure smooth installation and long-term operation.
