Bag Filter

Provides Excellent Filtration

This reasonably priced FSI Bag Filter Vessel is designed to allow high flow rates through a single reusable bag filter. It is rated at 75 gpm for clean water. (For particulate laden water and/or to extend time between cleaning, we recommend a design flow rate below 40 gpm.) For higher flows, use two or more in parallel. To further extend time between cleaning, place a larger micron filter before a smaller micron filter in series. The vessel is made of polypropylene with a threaded lid, O-ring and removable internal basket for easy bag removal. This vessel has 2” FNPT inlet and outlet and 1/4” FNPT lid vent. Optional pressure gauges for lid vent are listed below.

This Filter Vessel is only compatible with the bags listed below. Bags are 6” dia. x 20” length with 2 ft² of surface area. They are fitted with a ‘

“Polyloc Ring”, which seals directly against the filter housing, eliminating any chance of bypass. Vessels include housing, lid, retainer basket, and 2 plastic leg/foot assemblies easily cut to your required height. Maximum pressure is 100 PSI @ 110°F. Shipping weight is 10 pounds. Made in USA. One-year warranty.

FSI filter vessels can be used with either a filter bag or a filter cartridge, allowing choice of a filter media that precisely fits your needs. Filter bags feature a “Polyloc snap-fit” bag seal that creates a hermetic seal within a filter housing to prevent liquid bypass. They provide outstanding performance, twice the dirt handling capacity as a standard felt bag, and a no-bypass welded seam design. Bags are available in polypropylene, polyester, and nylon materials.

The following vessels are available: 90 gpm, 1 bag, 2” inlet/outlet: 200 gpm, 1 bag, 2” inlet/outlet: 400 gpm, 2 bags, 3”–4” inlet/outlet; 600 gpm, 3 bags, 3”–6” inlet/outlet; 800 gpm, 4 bags, 4”–6” inlet/outlet; 1000 gpm, 5 bags, 4”–8” inlet/outlet; 1600 gpm, 8 bags, 8”–10” inlet/outlet.

The gauge indicates when the filters is clean or when the bag needs cleaning. Requires a 3/16” drill to finish portholes, use only screws provided. Available in two models: small gauge provides visual indication of cleaning at 6–8 PSI, large gauge provides visual indication of cleaning at 15–20 PSI.
