SMBW 4000 Series Filters

Pentair SMBW 4000 Series Pool Filters

Fiberglass DE filter with built-in backwash valve Pentair SMBW 4000 SERIES D.E. filters are designed for optimal filtration efficiency, easy maintenance, and longer runs between cleaning. Their extraordinary dirt-holding capacity and easy cleanability makes them ideal for even large or heavily used pools.
The SMBW 4000 SERIES D.E. filters are engineered to provide high efficiency filtration with a minimum of maintenance. And when occasional maintenance is required, you'll appreciate the safe, user-friendly design of the tank's clamp ring, and the ease with which filters grids can be removed for cleaning.
Filtering with diatomaceous earth (D.E.) removes particles so small they are individually undetected by the human eye, but combine to decrease water clarity. 4000 Series™ filters remove the tiniest of contaminants, so your water truly sparkles. In addition to exceptional filtration, Pentair SMBW 4000 Series D.E. filters feature sheet molded fiberglass tanks and Noryl® rotary backwash valves for long life, dependable performance and easy maintenance.
