Product Details

Description

This premium Armstrong Dual Pressure Switch is a critical safety component designed for high-efficiency HVAC systems and gas-fired furnaces. As an essential air-proving switch, it monitors the pressure differential created by the draft inducer motor to ensure proper airflow before allowing the ignition process to begin. By detecting vacuum levels at dual setpoints of 0.45" WC and 0.80" WC, this switch prevents the system from operating under hazardous conditions such as blocked vents or blower failure. This durable replacement part is engineered for precision and reliability, helping to restore optimal performance and safety to your residential or commercial heating equipment.
