Neptune 5 Micron Filter Bag | Part #106453 for FTF Filter Feeders
The Neptune 106453 is the industry-standard 5-micron "fine" filter bag designed specifically for the Neptune FTF (Filter Feeder) series. This bag is the "workhorse" of side-stream filtration, offering a high-efficiency balance between flow capacity and superior sediment removal. By capturing fine rust, scale, and suspended solids, it provides essential protection for valves, pump seals, and heat exchangers in closed-loop systems.
