Notes

Product Overview

The Siemens QPL25 Series is designed for monitoring combustion air pressure in industrial and commercial burner systems.
It ensures that adequate airflow is present before ignition and during burner operation, serving as a critical safety interlock component.

The QPL25 series is commonly used in gas-fired and oil-fired burners installed in boilers, furnaces, and heating systems.
If the air pressure drops below the preset threshold, the switch signals the burner control unit to prevent startup or initiate safety shutdown.

Different sub-models within the QPL25 series provide various adjustable pressure ranges to match specific burner requirements.
