What it is
The air diffuser, listed as a scoop, is a Riello burner component used on RL series oil burners. It sits in the combustion air path and shapes the airflow as it leaves the blast tube, which influences how the fuel and air mix at the burner head. It is supplied as part of the Riello burner spares range.
