Product Details

Description

This high-performance differential pressure switch is a vital safety and monitoring component designed for commercial and industrial HVAC systems. Functioning as an air proving switch, it accurately detects the pressure difference between two points to ensure optimal airflow and system integrity. By monitoring the pressure drop across filters or verifying fan operation, this switch prevents the system from engaging under unsafe conditions, such as a blocked flue or a failed blower motor. It is a critical replacement part for maintaining the efficiency and safety of air handling units, furnaces, and ventilation systems. Engineered for reliability, this sensor helps prevent equipment damage and ensures consistent climate control performance.
