The ventilation filtration, filling, liquid level monitoring and temperature monitoring as well as safe oil sampling are among the basic functions of an oil tank. In the circuit diagram for the ventilation filter as per DIN 24557 T2, the FCT fluid control terminal offers these functions in a single, compact device. This considerably reduces the space required on the tank cover. The high functional density in a single unit reduces installation and procurement costs as well as logistics efforts considerably. Good access improves maintenance, the filling coupler prevents secondary contamination during filling
