- DIFF PRES. SW..74" W.C. PF
Bard 8406-060 is an OEM differential pressure switch set at 0.74 inches water column that helps your Bard wall mount or packaged HVAC equipment prove airflow and protect operation when pressure conditions fall outside the intended range. In the field, this style of switch is commonly used to monitor airflow across components such as filters or air moving sections so the unit can shut down or alarm instead of running with restricted airflow. When you are chasing nuisance trips, ventilation faults, or intermittent operation, replacing a weak or drifting pressure switch with the correct Bard part number 8406-060 helps restore proper control logic and dependable safety operation. Always confirm the pressure rating and tubing or port orientation match your original switch and the unit documentation before ordering.
