Description
The Nordyne 632614 Dual Pressure Switch is a safety device for HVAC systems that monitors and regulates airflow. It includes two pressure switches, each with a distinct pressure 0.40″ water column and 0.70″ water column. When the airflow pressure falls below the specified point, the primary switch turns on the blower motor to provide proper ventilation. The secondary switch serves as a safety backup, shutting down the device if airflow falls sufficiently below the second threshold to avoid harm. This dual-pressure switch is critical for ensuring proper airflow and preventing HVAC system failures.
