Franke’s corrosion-resistance Steel Series includes kitchen (pictured), prep and bar models that feature a 100% stainless-steel pull-down, dual-spray head that extends up to 21” and offers full and needle spray patterns. Includes two polymer plastic O-Rings to seal the waterways, ceramic cartridges and the spray hoses. Hose construction consists of a PE inner core protected by a low-friction, smooth nylon, braided, outside mesh. All but the potfiller uses a 35mm Kerox cartridge and Neoperl aerators, with a flow rate of 1.75 gal. per min.
