Description
The Lennox 25B19 Air Orifice 0.860″ ULN is a flow control element used in HVAC systems. It regulates air passage within burner or combustion-related assemblies by maintaining a precise opening size for controlled airflow. This component is mounted in furnaces or heating units where accurate air-to-fuel balance is required for stable operation. It operates as part of the internal metering pathway, assisting to ensure consistent combustion conditions and proper system performance across the heating part. The orifice assists in maintaining steady air distribution supporting efficient operation of related components and contributing to overall system functionality within heating applications.
