Description
The Field Controls CAS-1 Direct Connect Combustion Air System supplies outdoor air directly to a burner to support proper fuel burning inside heating systems. It operates using a motor-driven fan that draws external air through an intake path and delivers it through a sealed duct connection to the combustion chamber in HVAC systems, maintaining a steady air supply during operation. It is used in mechanical rooms or enclosed spaces where natural airflow is limited. Its direct-connect structure stabilizes combustion conditions, improves ignition stability, and reduces the air shortage affecting burner performance.
