The Elkay EF1500VRBMC Vandal-Resistant Retrofit Filtration Kit with Filter Status Monitor is designed to be used on existing non-filtered water coolers, drinking fountains and water bottle filling stations. The EF1500VRBMC includes the 51299C Watersentry VII filter, which has a 1,500-gallon capacity and is certified for reduction of lead, particulate class 1, chlorine, taste and odor. This retrofit kit is vandal-resistant, made from 20-gauge stainless steel to protect filter and discourage tampering. The versatile mounting box can be mounted virtually anywhere near an accessible water line. The filter status monitor notifies the user when the filter needs to be replaced.
