SPX Flow-Hankison 3146975 Fan Pressure Switch

The SPX Flow-Hankison 3146975 Fan Pressure Switch is a mechanical component used to monitor airflow pressure within compatible compressed air dryers and filtration systems. It detects changes in fan pressure and triggers responses to maintain proper air movement and protect the equipment from operational issues. Commonly used in industrial and commercial air handling applications, the switch is mounted within the fan or duct assembly to sense airflow conditions. In HVAC systems and related compressed air setups, it ensures that fans operate within designated pressure ranges, contributing to stable airflow and the coordinated operation of connected components.
