Product Details

Description

This high-quality Air Pressure Switch is a vital safety component for commercial and residential HVAC systems. Functioning as an air proving switch, it is designed to monitor the pressure differential within the unit, ensuring that the inducer motor is creating sufficient airflow and that the venting system is clear of obstructions. By verifying proper draft before allowing the ignition sequence to proceed, this switch protects the equipment from malfunctioning and prevents hazardous operation. It is an ideal replacement part for rooftop units (RTUs) and packaged heating systems that are experiencing ignition failures or intermittent shutdowns due to airflow detection issues.
