Description
The Cleveland Controls NS2-1341-01 is a precision differential air switch engineered to prove airflow in HVAC systems, combustion equipment, and air-handling applications. With a factory-set pressure differential of .034″ WC and a reset point of .04″ WC, this switch is ideal for low-pressure sensing applications where reliable, repeatable performance is critical.
How It Works
The NS2-1341-01 monitors differential air pressure across a duct, filter, fan, or blower assembly. When airflow meets or exceeds the calibrated setpoint, the switch actuates its internal contacts — providing a proven-airflow signal to the system controller. This makes it an essential safety and control component in furnaces, rooftop units, air handlers, and draft-proving circuits.
