How to Choose a Bag Filter Housing for Process Liquids
A bag filter housing is a practical choice for many industrial liquids, but the correct model depends on more than flow rate. Housing size, pressure rating, sealing method and liquid compatibility all influence performance.
Selection Guidance
When this matters
Start with flow rate and pressure drop. A housing that is too small may force high velocity through the bag, shorten service life and increase replacement frequency. Multi-bag housings are usually considered when higher flow or longer runtime is needed.
What to compare
Material compatibility is essential. Stainless steel housing material, gasket material and basket construction should match the liquid chemistry, temperature and cleaning method. For many process liquids, 304 or 316 stainless steel is reviewed first.
Common mistakes to avoid
Maintenance access should be considered early. Cover opening style, installation height, bag changeout space and drainage arrangement all affect daily operation. A housing that is easy to service is often more valuable than one selected only by a low purchase price.
Information to prepare
Useful quotation data includes liquid type, solids loading, flow rate, operating pressure, temperature, connection size, micron rating and whether the system is batch or continuous.
