It is manufactured to clean the sediment that forms on the bottom of the tank over time and causes the fuel quality and stored fuel volume to decrease. With this system designed by Neftgen, there is no need to enter the tank or stop the fuel supply process. While the sales process is in progress at the station, fuel cleaning can be done. Filtration can be performed according to different fuel and pollution levels. The system can also be easily used to draw fuel or water from tanks or dispenser sumps.
