The Aries AF-20-3690-BB utilizes the advanced media technology of ResinTech® SIR-900 media. AF Series cartridges remove Fluoride by a chemical reaction with the media. ResinTech® SIR-900 is a synthetic aluminum oxide that is specially processed to have minimum fines and other foreign matter. It has minimal shrinkage/swelling and low-pressure loss. The product is physically stable and can be used over a wide pH range.

Features:

• Made with FDA approved materials
• Fits 20" Big Blue Housings
• Uses Resintech SIR-900 (activated alumina) media
• Flow Rate: 0.2 GPM
• Capacity: 2,500 Gallons
• Made in the USA

Fluoride reduction is flow and pH sensitive. Best results with this filter are obtained at a flow rate of 0.2 GPM and an influent pH of 5.5. Higher flow rates and higher or lower pH causes a significant loss of capacity.
