Cleveland Controls AFS-262-320 Pressure Switch N/O 0.05-2" WC 120V

The Cleveland Controls AFS-262-320 Pressure Switch is used in HVAC systems to measure the air pressure. This normally open switch has a pressure range of between 0.05-2”WC and is powered by 120V to close an electrical circuit when the pressure reaches a setpoint. It can also provide feedback in form of responses which can include turning on or off fans, opening or closing dampers or sounding of alarms. This switch is used in air handlers, rooftop units or VAV boxes to control air flow, maintain system efficiency and protect the equipment from pressure changes, which adversely affect the HVAC system efficiency and its overall saving.
