Backwash: 10 GPM

Media Specifications:
Granular Activated Carbon (GAC) - Primary Filtration Media
• Large surface area results in an exceptionally high capacity and efficiency. Activated Carbon is very hard so losses due to attrition are kept to a minimum. GAC constitutes an excellent filtration media, having a density with a balanced pore structure for more efficient operation. GAC even with it’s high capacity should be replaced when the filter loses the capacity for removal of taste and odor.

• GAC is the most effective media for the removal of contaminants from water. GAC has the unique ability to adsorb chlorine from water and is the most preferred method for the complete protection from trihalomethanes (THM’s) and has been proven 99% effective.

• However, no one media, resin or cartridge is capable of all things.
Please refer to the GAC reference chart for capacities.

• A high grade, dedusted GAC with an iodine rating of 1200 has been selected for all CWL and EWS Series.

Bed Depth: 26 - 30 in., Backwash Rate: 8-10 gpm
Backwash Bed Expansion: 30 - 40 % of bed depth

Filter Ag
Used to afford maximum removal of suspended matter throughout the filter bed and to allow the GAC media to work at maximum efficiency.
* Acts as a Pre-Sediment (20 micron) media
* Less pressure loss, increased filter capacity
* Light weight, lower backwash rates.

Under Bed Filter Sand
Keeps riser in place and promotes better flow and even water distribution through media bed and during backwash cycles to lift bed uniformally.

Conditions of Operation:
System Service Flow Rate - up to 50 gpm
Media Service Flow Rate - 5 gpm / sq. ft.
Min/Max Water Temperature: 40º / 80 ºF - 4.4 / 62.8C
Min/Max Water Pressure: 40 PSI / 75 PSI
Warning: Install Pressure Reducing Valve (PRV), by code in places, to prevent pressure surges and warranty issues
