The Pro-Flo product line now offers a chrome-plated, lead-free brass bubbler that features a flexible guard molded with AgION antimicrobial technology. The flexible guard helps prevent chipping teeth and is said to be ideal for schools, parks and recreation facilities, wherever children come in contact with drinking fountains. The unique flexible guard is manufactured with AgION technology, a silver-based compound that is activated upon contact with moisture and inhibits and reduces microbial growth.
