In our Foundry, eliminating downtime is critical. These bag filters have improved the cleanliness of our cooling towers, heat exchangers and closed loops exponentially. We no longer schedule regular cleanings.

Multi- Bag Filter Housing Unit Features and Benefits

Tile 2

If your filtration application needs include higher volumes and flow rates but prefer less frequent media bag changes, a multi-bag filter housing system may be the best option for you. Multi-bag filter housings offer fast turnaround times and reduce downtime during bag media filter changes. Compression bag clamps guarantee a positive seal and offer zero discharge — no process fluids are lost. These features also prevent bypassing and leakage.

Our ergonomic design makes operation, repairs, and cleaning of the multi-bag filtration housing system quick and easy. Stainless steel prevents corrosion and is easy to sanitize. Over-the-top design and spring lids make cleaning and changing filter bags easier. Side drain ports allow for chaining multiple units together, to run in parallel, or alternate for a continuous source of the filtered fluid. Because you can simply replace the filter media, our bag housing units offer huge savings over cartridge filters.


Multi-Bag Filter Housing Unit Sizes and Functions

At Filter Sciences, we offer a wide variety of multi-bag filtration housing systems that range from 1 to 12 cells. Each of the cells is capable of up to 200 GPM flow.  If 12 cells are not enough for your application needs, all of our units can easily be flanged together, run in parallel, or chained to alternate for continuous filtration. Piping multi-bag units together permit disabling one to service it while flow continues through the other to offer continuous use and no downtime.  

Because our filter housing units are capable of using any of hundreds of bag filter media options, including multi-basket strainers, they can be used in nearly any application you need. Made of stainless steel, our multi-bag filter housing units are corrosion-resistant and able to be used in many applications. Common applications of our units include metalworking, pharmaceuticals, hydraulic fracturing, food and beverage, paint and lacquer, chemical processing, and the automotive industry. Discover all of the uses on our application page.

Twin or Multiple Bag Filter Housing System

Tile 4

Whether you need more than 12 bag filtration cells in your housing unit or your application requires more frequent filter media changes or strainer cleaners, using modified bag housing units or flanging several together may be the better option for you. At Filter Sciences, we offer twin and dual bag filter housing units in both the single and multi-bag options. Additionally, all of our bag filtration housing systems feature side valves to allow the units to be flanged together. Creating a multiplex filter housing system allows for cleaning, servicing, and bag changes without disrupting flow and permitting continuous operation. Contact our engineers to discuss your specific filtration needs, and let us customize a bag filtration system that works for you.
