Oil filter/deaerator BOB De Dietrich 7311025

The oil filter/deaerator BOB is a combined component that filters impurities and removes air from the oil supply in a burner system. This helps protect the burner nozzle and pump from contamination and ensures smooth combustion. Regular replacement of this filter/deaerator is key to maintaining boiler efficiency and preventing operational issues. It is a practical maintenance part for any oil-fired heating system, particularly those using BOB burners.
