Bard 8406-072 - Differential pressure switch
Bard part number 8406-072 is an OEM differential pressure switch set to approximately 0.51 in. w.c. (plus or minus 0.05) and designed to open on a falling pressure signal, helping the unit verify proper airflow and safe operating conditions before allowing the system to run. In Bard wall mounted equipment, pressure switches are commonly used as a safety proving device tied into the control circuit, so matching the correct setpoint and switching action is critical to prevent nuisance lockouts or unsafe operation. This Bard factory replacement is intended to restore correct pressure sensing and reliable unit sequencing when the original switch is out of tolerance or intermittently failing, and it should be selected by exact part number and confirmed against the unit model and wiring diagram for proper fit and function.
