LT2 Pleated Microglass Cartridges

LT2 Pleated Microglass Cartridges

Meets Long Term 2 (LT2) Requirements for Ground Water Under Direct Influence of Surface Water (GWUDI)

Certified: NSF/ANSI Standard 61 Drinking Water System Components - Health Effects

 
High flow capability
Low initial pressure drop
Lower overall operating cost
Increased contaminant removal
Longer filter runs for fewer change-outs

Features

  • NSF-61 Listed filter media removes cyst-sized particles for safe, cyst-free drinking water
  • Pleated microfiber media provides more surface area for longer filter life and increased particle removal
  • Patented Dual Durometer end caps ensure positive end cap sealing
  • End caps, center tubes and media are thermally bonded as one integral component for added strength and to provide superior end sealing
  • 120 sq. ft. media (surface area) in a single cartridge design
  • FDA Listed Materials: Manufactured from materials which are listed for food contact applications in Title 21 of the U.S. Code of Federal Regulations

Applications

  • Surface Water Treatment Rule (SWTR) LT2
  • Ground Water Under Direct Influence (GWUDI)
  • Municipal Drinking Water

Independent Lab Validated

To verify the performance of the Harmsco LT2 cartridge and NSF filter housing, IBR, a highly respected independent testing facility, was selected to conduct a challenge test outlined in the LT2 ESWTR Toolbox Guidance Manual 8.4.1. This defines the maximum challenge particulate based on detection limit and acceptable cryptosporidium surrogate…2 microns in this test. The “terminal” pressure drop was determined by Harmsco to be 30 psi. The Harmsco LT2 cartridge was tested in a single-pass challenge test at 3 points…after initial flushing, at 15 psi differential, and again at 30 psi differential.
