Description
The Cleveland Controls NS2-0000-08 Field Adjustable Switch with Bleed Hole is a compact air pressure sensing component used in commercial airflow control units in HVAC systems. It is used to monitor differential air pressure and provide a consistent on/off switching signal. It has an integrated bleed hole that helps to stabilize operation by pressure buildup at the sensing port, improving consistency in air flow conditions. It is placed in furnaces, air handlers, or combustion air systems where it verifies proper draft or airflow before enabling ignition or continued operation and provides protective and controlled system performance.
