The Speakman Lifesaver SE-820 8 In. Stainless Steel Shower Head features a high performance spray engine that delivers a superior performance and spray coverage when your life is on the line. Equipped with a self-draining system, the Lifesaver empties any excess water after activation, meaning the unit will never collect water and freeze up. An internal flow control reduces water output to 20 GPM, allowing pressure to balance perfectly between the eyewash and shower. Plus, the Lifesaver retrofits to any existing emergency shower station, meaning there''s no need to install a new combination station. The Lifesaver is a 100 percent ANSI/ISEA Z358.1 Certified emergency shower head and features an ABS plastic spray engine with an 8-inch stainless steel shroud.
