Bard 8301-012 - Air Flow Switch

The Bard 8301-012 Air Flow Switch is an OEM electrical safety and proving device used in Bard wall-mount HVAC equipment to confirm blower airflow before allowing normal operation. When airflow is inadequate due to a failed blower, blocked return, dirty filter, or other restriction, this switch helps signal the control circuit to prevent improper heating or cooling operation and nuisance trips. It is a direct-fit Bard replacement part intended to restore reliable system monitoring and proper interlock operation; verify the part number and the unit model and serial information to ensure correct compatibility before ordering.
