120B4 / 122B4 (MULTI-PORT) HOUSINGS

The 120B4 / 122B4 series are versatile sample process filters, which encompasses the standard features of our 120 series housing, but also allows greater installation flexibility. The B4 has four ports in the head and one in the bowl. The four head ports allow multi-sample streams to be serviced by one filter assembly or the multiple ports may be used for a gauge, vent, and/or drain.

If using a head port as a drain, the B4 should be installed horizontally, or on a slight incline for the liquid to drain properly. When using the head port as a drain, element service is fast and simple since no connections need to be broken. The built in support core provides extra element stability in liquid streams, and superior collapse safety in heavily contaminated gaseous samples. The filter element merely slips over the core and is held in place by the bowl. An integral mounting bracket is included with the assembly.

A model 120B / 122B (two head ports and one bowl port) is also available.
