FiltEdge can help you do the selection analysis. If you have the SDS data of the slurry or your requirements, we can help you analyze the filtration medium, corrosiveness, flow rate, precision, pressure, temperature, etc., and then choose the right bag filter unit for you and provide design drawings.
The replacement frequency of the filter bag depends on the impurity content of the filter media, the higher the impurity content, the higher the replacement frequency, usually about 1-7 days. You can install a pressure gauge on the bag filter to determine whether the filter bag needs to be replaced by the differential pressure value.
Our bag filters have a quick-opening filter, which makes the replacement of filter bags quick and labor-saving, and can be operated by one person.
Our bag filters are available in 5 materials, 304/316 stainless steel typically lasts 8-10 years, carbon steel lasts 5-7 years, and PP/PVDF typically lasts 6-8 years. Service life is not only related to the material, but also to how and how often the equipment is maintained and how well the initial filter purchased matches the operating conditions.
