ENPRESS LLC introduces its new Cartridge Tank™ filtration system for POE installations and applications. This patent-pending filtration system features an easy-to-access top and bottom opening for use with multiple filtration connections and solutions, in a lightweight and cost-effective package. The vessel features three optional top and bottom opening connections for use with a pressure release valve configuration or a control valve/in-out head, along with bottom or top drain plumbing connections for residential and light commercial installations. The no-tools-necessary, snap-ring design makes it easy to remove top and bottom opening connections to access the internal filtration solution. This is a direct replacement for 2.5- or 4.5-inch (63.5- or 114.3-mm) housings or SS cartridge housings and is an NSF 61-listed device that has been tested to 150-psi operating pressure. http://www.enpress.com, (866) 859-9274
