Franke’s Steel Series family includes kitchen, prep and bar models that feature a pull-down, dual-spray head that extends up to 21” and offers full and needle-spray patterns. All but one use a 35 mm Kerox cartridge and Neoperl aerators with a flow rate of 1.75 gpm. With its 1/2” flush cartridge, the potfiller has a flow rate of 2.2 gpm. The only exceptions to this all-stainless-construction are two polymer plastic O-Rings to seal the waterways, ceramic cartridges and the spray hoses.
