The Honeywell 14002913-001 0.005" Blue Filter Restriction Assembly is a flow-monitoring part in the HVAC systems in boilers and hydronic heating units. It compares the difference in pressure across a filter or orifice to identify when the flow limiting happens, to enable the control system to monitor the condition of filters or fluid flow. This assembly is installed in the supply line where monitoring is needed to give a specified point of restriction and a feedback signal to control module. It assists technicians and system control low flow and ensures the exact work and safety of residential and commercial systems.
