FAQ

What is a bag filter housing used for?

Bag filter housings are used for bulk solids removal, process protection, and applications with heavier or variable solids loads. Typical industries include chemical processing, petrochemical, food and beverage, pharmaceutical, water treatment, and wastewater treatment. They are particularly effective where large amounts of suspended solids must be removed economically.

What is the difference between a bag filter and a cartridge filter?

Bag filters use a fabric or mesh bag as the filter medium, offering high dirt-holding capacity and fast changeout for bulk solids removal. Cartridge filters use pleated, melt-blown, or membrane elements for finer, more controlled filtration. Generally, choose bag filters for heavier solids loads and economical bulk removal; choose cartridge filters for final barrier filtration, RO/DI pretreatment, or high-purity applications.

How often should a bag filter be replaced?

Replacement depends on solids loading, flow rate, and the pressure differential across the bag. A common guideline is to replace the bag when differential pressure reaches 0.5–1.0 bar above the clean starting pressure, or when flow rate drops noticeably. In heavy-load applications, bags may require daily or weekly changes; in cleaner streams, replacement intervals can extend to several weeks.

What materials are available for bag filter housings?

Standard housing materials include carbon steel, stainless steel 304, 316, and 316L. For highly corrosive environments, duplex stainless steel 2205 and other specialty alloys are available. Filter bags are available in polypropylene, polyester, nylon, PTFE, and other materials to suit different chemical compatibility and temperature requirements.

How do I choose the right bag filter housing?

Consider the fluid type and chemical compatibility, required flow rate, operating pressure and temperature, solids loading and particle size, bag size and micron rating, connection type, and available installation space. Providing these details in your inquiry ensures the housing matches your process line and maintenance preferences.

Can bag filter housings be customized?

Yes. We customize housing material, bag size and quantity, inlet/outlet configuration and connection standards, cover opening type, surface finish, and internal weld treatment according to your specific process requirements. Custom designs are available for special pressure ratings, temperature conditions, and space constraints.
