Neptune FBK-2 Filter Bag Kit (Conversion Kit for DBF-2 / VTF-2)
The Neptune FBK-2 is a complete internal retrofit kit designed to convert your standard 2-gallon "Dome Top" bypass feeder into an active side-stream filtration system. By installing this kit, your feeder can simultaneously dose chemicals and capture suspended solids, scale, and rust chips that would otherwise damage your pumps, seals, and heat exchangers.
What’s Included in the FBK-2 Kit:
- (1) Stainless Steel Bag Hanger / Frame: Precision-sized specifically for 2-gallon tanks.
- (1) 30-Micron Drawstring Filter Bag: The standard high-flow bag for reliable sediment capture.
- (1) Inlet Tubing & Internal Fitting: Corrects the flow path to ensure all water passes through the filter bag before exiting.
Product Specifications:
- Feeder Compatibility: Fits Neptune DBF-2, DBF-2HP, VTF-2, and VTF-2HP (2-Gallon Models).
- Replacement Bags: Uses the PAC-6 series drawstring replacement bags (30-Micron).
- Installation: Simple drop-in design; no drilling or tank modifications required.
*** COMPATIBILITY CHECK ***
- Use this kit ONLY if you have a "Dome Top" feeder (DBF or VTF models) and want to add filtration.
- If your feeder is an "FTF Series" (it already has a stainless steel basket), you do not need this kit—you simply need the ring-top "sock" filters.
