DualGuard®

Graver Aegis® DualGuard® Septa are unique two-phase backwashable filters that facilitate both dissolved ion contaminant and particulate reduction. The outer layer may be constructed with filament windings for optimum precoat processing or with a membrane sheath that provides integrated dual phase particulate filtration at optimum efficiency. The inner phase is constructed with pleated polypropylene media in a wide choice of pore sizes.

DualGuard Septa are available in top and bottom tube sheet designs for all manufacturers’ vessels with an assortment of end fittings available to custom fit or improve each plant’s specific installation requirements.

TurboGuard® RF Series

"Graver TurboGuard® RF Series filter is another in the series of larger geometry filters to handle higher volume applications with fewer filter elements."

Key features

Flow is from the inside core to the outer pleats
TurboGuard Filters are wrapped in a onepiece extruded outer cage preventing
both media migration during inside out flow, and tearing during removal
Onepiece molded end caps, including moldedin bail for secure handling
during installation and removal
Thermally bonded construction and low pressure drop at specified flow rates
Maximum Flow Rates (lower flow rates will affect performance)
20” Element up to 175 gpm (663 lpm)
40” Element up to 350 gpm (1,325 lpm)
60” Element up to 500 gpm (1,893 lpm)
Absolute retention ratings from 1 to 100 microns
Capable of flow rates up to 80 GPM in a single element
Multilayer pleated construction with optimized surface area
Retrofits competitive large diameter filter housings utilizing the "740" design
Thermally bonded construction
All polypropylene construction provides for a high level of chemical compatibility
