Stainless Steel Bag Filter

Our stainless steel bag filter is a high-performance, multi-purpose pressure filtration equipment, designed for efficient solid-liquid separation in various industrial fluid treatment scenarios. 

Adopting a fully enclosed structure and made of high-quality food-grade/industrial-grade stainless steel (SUS304/SUS316L), this filter consists of a sturdy filter cylinder, reinforced support basket, high-precision filter bag, quick-opening mechanism and inlet/outlet connectors, with a compact and reasonable overall structure, small footprint and strong adaptability.

Working under pressure, the fluid to be filtered enters the filter cavity from the side or top inlet, passes through the filter bag supported by the metal basket, and impurities are trapped inside the filter bag, while the purified fluid flows out from the outlet to achieve efficient purification. It supports single-bag and multi-bag customized configurations, can handle different flow rates and filtration requirements, and realizes zero material loss during filtration, with stable and reliable operation effect, which is widely recognized as a cost-effective filtration solution in the industrial field.

Frequently Asked Questions (FAQ)

1. Q: How to choose between SUS304 and SUS316L stainless steel materials?

A: SUS304 stainless steel is suitable for neutral fluids, conventional water treatment, food and beverage and other non-corrosive or weakly corrosive scenarios, with cost-effective advantages; SUS316L stainless steel has stronger acid and alkali resistance and high temperature resistance, suitable for chemical corrosive fluids, high-temperature media and other harsh working conditions, you can choose according to your fluid properties and use environment.

2. Q: How often does the filter bag need to be replaced?

A: The replacement cycle depends on the impurity content and operating time of the fluid. Generally, it is replaced when the equipment pressure difference increases to 0.1-0.15MPa or the filtration flow decreases significantly; for fluids with low impurity content, the replacement cycle can be as long as 1-3 months, and for high-impurity fluids, it needs to be checked and replaced regularly.

3. Q: Can the filtration precision be customized according to my needs?

A: Yes, we support customized filtration precision from 1μm to 400μm, and can match special filter bags for high-viscosity, high-temperature and other special fluids; at the same time, we can customize single-bag/multi-bag specifications, inlet/outlet calibers and installation methods according to your flow and site requirements.

4. Q: Is this filter suitable for high-viscosity fluids such as oil and resin?

A: Absolutely. Our stainless steel bag filter has a large filtration area and strong fluid passing capacity, which can efficiently filter high-viscosity fluids; we can also recommend targeted filter bag materials and equipment configurations to ensure smooth filtration and avoid blockage.
