AFR-Series

The revolutionary Eaton AFR-Series delivers
high-flow filtration of water-like liquids at
retentions as low as 1 micron in a compact

one-square-meter footprint.

FeaTureS/BeNeFITS
• Solids removal from 1 to 1,700 microns
• Flow rates up to 2,000 gpm (454 m /hr)

• Broad selection of filter media materials and retentions suitable
for a wide range of applications
• Numerous automated backwash options for operator-free
service and minimal backwash effluent (<2% of system volume)
• Smooth pipe and nozzle connection transitions to avoid dead
