Advantages of multi-stage stainless steel bag filter
1. The processing flow per unit filtration area is large, the filtration resistance is small, and the filtration efficiency is high. The function of a system filter is equivalent to 5~10 times that of ordinary filters, which can greatly reduce costs. The design flow can meet the requirements of 1 ~ 500m3 / h, and the cost is low.
2. Centrifuge pump is equipped well. Support continuously and stable working.

3. High filtration accuracy, suitable for any fine particles or suspended matter, the filtration range can be from 0.5 to 200 microns.
4.The filter is free of cleaning, and the replacement of the liquid filter bag or filter element can be completed in 30 seconds, which is convenient and fast, saving labor and time.

5. The bag filter material includes stainless steel SUS304, and stainless steel 316L can be optionally replaced.
