Carrier 5390 Airflow Proving Switch

The Carrier 5390 Switch Airflow Proving is a unique component of HVAC that is used to prove the airflow in systems. It is a device that works at temperatures ranging from 40°F to 99°F and ensures the identification of airflow before the system turns on. Measuring 0.0047 cubic inches with a white color, this switch is small and can easily fit into most HVAC systems making it more reliable and safe. It is normally used in Carrier air handling units as well as furnaces. Some of the benefits include better performance of the system, better energy utilization, and protection from wrong airflow that might cause harm to HVAC systems to function as required for the expected period.
