Multi-Bag Housings BFS Series

Our new multi-cavity bag housings are designed for high flow industrial and commercial filter applications, and manufactured from 304L or 316L stainless steel for maximum durability with many standard features. The clamp style housing is fast becoming a market leader with its quick clamp closer and exceptional value. The heavy duty design of the swing bolt closure and zinc plated steel davit assembly make it a perfect choice for your larger flow applications. Protective poly coat over stainless steel is the standard finish, with optional 134 epoxy coating for seawater or corrosive applications. We offer the multi series housings in a 2, 3, 4, 5 and 6 round design.

Multi-Bag vessels are designed to handle those high flow applications where a single bag unit is not sufficient.These bag filter housings offer a wide range of flow capacities and contaminant-holding capabilities. Our multi-bag system enables high flow rate through a single unit like the smaller size filtering vessels.
