Engineering summary from PDF text extraction for RFFE20-BB Radial Flow Cartridges. Verify every value with the OEM datasheet.
Summary
Product Identification
The RFFE20-BB is a Radial Flow Iron Reduction Cartridge designed for use in PENTEK® 20-inch Big Blue® filter housings.
Key Features
- Easily and effectively reduces up to 3 ppm of dissolved iron from water.
- Improves flavor and reduces the metallic taste caused by iron.
- Helps to eliminate orange and brown stains often found in sinks, toilets, and tubs.
- Reduces the possibility of pipe and water heater damage.
- Adds no harmful chemicals to the water, making it safe for drinking water applications.
Installation Notes
- Should be installed on the main cold water line after the pressure tank or water meter.
- For best results, pre-sediment and post-carbon treatment is recommended.
- New cartridges, after installation, should be flushed with sufficient water to remove all traces of fines (very fine powder) from your water system before use.
Operating Limits
- pH: >7.0
- Silica: <100 ppm
- Manganese: <1 ppm
- Iron: <3 ppm
- Iron Bacteria: None
- Hydrogen Sulfide: None
- Water conditions outside of these specified limits may lead to a shortened filtration life. If your water contains Iron Bacteria, shock chlorination is recommended.
Approximate System Life
The following table shows the approximate system life, based on test results obtained using the RFFE20-BB in combination with an RFC20-BB cartridge.
| Iron Level in Water | Total Gallons Water Used | 250 GPD (Four People) | 125 GPD (Two People) | 75 GPD (One Person) |
|---|---|---|---|---|
| 3 ppm | 26,000 gal | 104 days | 208 days | 416 days |
| 2 ppm | 40,000 gal | 160 days | 320 days | 640 days |
| 1 ppm | 80,000 gal | 320 days | 640 days | 1280 days |
| 0.5 ppm | 160,000 gal | 640 days | 1280 days | N/A |
Warnings and Cautions
- WARNING: Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the unit.
- CAUTION: Protect against freezing to prevent cracking of the filter and water leakage.
