Description
The Price Industries 019425-002 Airflow Switch is a differential atmosphere sensing tool to detect the presence or absence of air movement within ducts and equipment. It operates using an internal pressure-sensitive mechanism that responds to airflow changes and sends an electrical signal when it reaches or drops below a set threshold. HVAC systems rely on this feedback to confirm fan operation, protect equipment, and ensure proper ventilation control during operation. Integrated in pipes or air handling units, it serves as a monitoring safety component that supports system verification, operational reliability, and stable airflow performance in controlled conditions.
