Aries (AF-20-3318-BB) 20"x4.5" Big Blue Scale Inhibitor Phosphate Filter
AF-20-3318-BB 20"x4.5" Big Blue Scale Inhibitor Phosphate Filter
Polyphosphate Treatment Process
Water Meets Phosphate
Incoming water flows through densely packed food-grade polyphosphate crystals inside the 20" x 4.5" cartridge body.
Mineral Binding
Phosphate ions bind to calcium, magnesium, and iron particles in solution, keeping them suspended and preventing precipitation as hard scale deposits.
Surface Coating
A microscopic phosphate film forms on metal surfaces downstream, inhibiting corrosion and providing a barrier against oxidation and rust formation.
Filter Details
| Model Number | AF-20-3318-BB |
| Dimensions | 20" x 4.5" |
| Housing Compatibility | Standard Big Blue 20" housings |
| Media Type | Food-grade polyphosphate crystals |
| Certification | NSF Standard 61 tested |
| Construction | FDA-approved materials |
| Service Life | Varies by water hardness and flow rate |
Recommended Applications
The Aries AF-20-3318-BB is designed for whole-house water systems, ice machines, coffee and vending equipment, food service operations, tankless and standard water heaters, evaporative cooling systems, and any commercial or residential application where hard water causes scaling or corrosion. Install this filter in any standard 20-inch Big Blue housing rated for the flow demands of your system. Polyphosphate treatment does not remove hardness minerals or reduce TDS, but prevents them from forming visible scale deposits on surfaces and equipment.
