Specifications

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
