Description
The Cleveland Controls NS2-1365-05 is a dependable air proving switch engineered to verify the presence of airflow in commercial and industrial HVAC systems. By confirming that adequate air movement exists before allowing downstream equipment to operate, this switch plays a critical safety role in forced-air heating, ventilation, and air handling applications.
How It Works
The NS2-1365-05 senses differential air pressure across a duct or air handler. When airflow meets the required threshold, the switch closes its electrical contacts to signal the control system that safe operating conditions exist. If airflow drops below the set point — due to a failed fan, blocked filter, or closed damper — the switch opens, interrupting the control circuit and preventing unsafe operation.
