Johnson Controls P233A-4-AHC Differential Air Pressure Switch

The Johnson Controls P233A-4-AHC is a differential airflow air pressure switch that is used to define airflow of HVAC systems. This surface-mount switch is designed to provide reliable operation in different conditions with the operating voltage of 24V and the current of 10A. This is suitable for demanding operating temperature range of -40°F to 150°F which makes installation easy. To ensure that right air flow is achieved and prevent system failure, this switch is commonly fitted in commercial HVAC applications. It reduces energy consumption, enhances internal environment quality, and ensures maximum system efficiency by measuring pressure differences.
