The Speakman SEF-1850 Eyesaver combines a fully functional lab faucet with an independently operated aerated eyewash. Two separate water supplies built within the single-post, solid-brass frame ensure cold to tepid water will constantly flow from the eyewash, regardless if hot water is simultaneously running from the faucet. The SEF-1850 is a unique eyewash that saves valuable counter space, solves concerns associated with faucet-mount eyewash systems and is 100% ANSI Z358.1-certified.
