The United Electric J21K-232 Differential Pressure Switch SPDT 0–25 PSI (NEMA-4) is a critical control component designed for HVAC air handlers, fans, and ventilation systems. It monitors pressure differences across filters, ducts, or blower compartments and triggers or interrupts electrical circuits when pressure reaches preset thresholds. This helps ensure proper airflow and system safety. Benefits include improved system efficiency, protection against blocked filters or duct obstructions, consistent airflow regulation, and enhanced longevity of HVAC equipment through proactive pressure monitoring.
For an efficient and reliable HVAC system, the United Electric Differential Pressure Switch is a great choice for optimal system performance.
