Model No. of filter in photograph is BRT6RBZ102.
Features and Benefits ■ Filter is mounted in the tank and flow comes to
it from a pipe connection below it or from the side
■ Optimal flow conditions created by flow from beneath guaranteeing optimal air separation, even tank mixing, and long element service intervals
■ Patented de-aeration windows around the housing offer superior air bubble coalescence in a 360 degree discharge
■ Quality Protected Inside-Out Flow Element Design
