HAGO Manufacturing Co.'s upgraded Model Dual Filtration Nozzles are available through traditional supply houses that stock burner supplies. The DFN filters the oil all the way up to the metering slot. This extra filtration maintains constant oil flow within the burner and avoids plugging caused by fuel impurities. HAGO's DFN is helpful for burners firing at 1.00 gph and less.
