Cleveland Controls NS2-1023-00 Air Intake Pressure Switch

The Cleveland Controls NS2-1023-00 Differential air pressure switch is used in HVAC systems to provide control of air intake. It measures pressure fluctuations between the external air and the internal atmosphere of the equipment. When the pressure differential gets to a certain level, the switch turns on or off an electrical circuit as a response. This is vital, especially for designing proper airflow in rooftop units, air handling equipment, makeup air, and others. They include avoiding problems due to blocked filters or ductwork, improving system efficiency by maintaining the right airflow for combustion or ventilation and increasing safety by avoiding back-drafting in heating applications.
