This is the Sunfab solution: 1. Air bubbles from the return oil are guided by the oil flow up to the oil level (venting area) via an oil pipe. 2. Drainage connection/cooling connection close to the bottom far from the suction connection. 3. Large return filter corresponding to 4 x the pump flow. 4. Separate breathing filter, which is fitted protected from water and dirt. 5. Suction connection close to the bottom of the tank on the opposite side to the return filter. 3403GB0611 Produced in Sweden by� ���������������������� Bohman Information AB / Gävle Offset 6. The net volume of the tank should be at least 1.5 x the pump flow and positioned so that the oil level lies above the pump. Sunfab Hydraulics AB, Box 1094, SE-824 12 Hudiksvall, Sweden.
