"Constructed from 316L stainless steel, the heavyduty bag housings offer durability and resistance to high temperatures, pressures and aggressive chemicals. As standard all housings are built to include inlet and outlet pressure gauge ports to help monitor system performance, vent and drain ports for efficient filter changeout with adjustable mounting legs for installation ease and housing stability. Size 3 and 4 bag filters are ideally suited to batch processes or multi-line applications where economic costs and frequent changeouts are required. The reduced footprint of a size 3 and 4 bag housing also makes these suitable for applications with space limitations."
