Franklin Electric Sterling Water DF20 Non-backwash Filter

Product Description

The Franklin Electric Sterling Water DF20 is a 2.0 cubic foot (CF) non-backwash filter designed for residential and light commercial water treatment applications. Unlike standard backwashing filters, this unit operates without a drain connection or backwash cycle, making it suitable for installations where waste water discharge is limited or not practical. It is typically installed by licensed plumbers or water treatment technicians as part of a whole-house or point-of-entry filtration system.

The DF20 is suited for whole-house water treatment setups where a low-maintenance, non-backwash filtration approach is preferred. Its 2.0 CF media capacity supports adequate flow rates for residential service. It is sold as a single unit and is intended for use in compatible water treatment filter systems requiring this tank and media size.
