Inserto filtrante doppio DUNGS MB 405 / 407

Dual filter element DUNGS for regulators MB 405 and MB 407 is a replaceable part of the gas filter that cleans gas from mechanical impurities. This element is suitable for installation in these models of combined regulators, widely used in burner devices and boiler installations. The dual filter design increases the filtration area and reduces replacement frequency compared to single elements. Using the original DUNGS filter element guarantees reliable operation of the equipment and compliance with technical requirements. Regular filter replacement prevents contaminants from entering the gas valve train, which contributes to stable burner operation and reduces repair costs. The element is easily replaced during routine maintenance.
