Category: High Flow Filters
Series: UF
Model format: `UF-[MICRON][RATING]-[LENGTH]-[SEAL]-[OPTIONS]`
Example: `UF-1-20-EP-61`

## Overview
Absolute-rated pleated cartridges feature a 6-inch diameter and inside-to-outside flow to deliver up to 300 GPM per 60-inch element with high dirt-holding capacity and thermally bonded, NSF61-compliant construction for long service life and reduced operating costs

## How It Works
Fluid enters the core and flows inside-to-outside through pleated filter media that traps solids, while O-ring–sealed end caps prevent bypass and clean filtrate exits the outer cage

## Applications
- RO/UF pretreatment and plant/utility water polishing
- Desalination intake/well water sand & silt and wastewater/produced-water solids removal
- Chemical, glycol, and coolant loop prefiltration at high dirt load with extended runs
- Power: boiler feed/condensate and cooling-tower sidestream particulate control
- Electronics DI/RO rinse and marine/utility water high-flow particulate reduction
- Data centers: TCS CDU filtration, FWS cooling tower, chilled water filtration
