Function, section Combination of flange-mounting filling filter and cap removable over the bayonet lock as air breather with internal filter element. The filter element must be exchanged with the cap. The breathing filters are used in hydraulic systems for filtration of the suction air of the fluid tank. They are designed for installation on fluid tanks. Type FEF 0 By default, the cap (1) is connected via a chain (7) to the base (3). Depending on the process cycles, the air and contamination are drawn into the fluid tank. By use of our breathing filters, air circulation at the fluid tank...

Mounting, Commissioning, Maintenance Mounting ▶ Filter connection must correspond to the hole pattern (DIN 24557-2) at the tank. ▶ Position the seal on the hole pattern at the tank, insert the filling strainer and apply the second seal. ▶ Over the flange, all parts are fitted at the tank. For this purpose, the screws included in the scope of delivery (see tightening torques) must be used. ▶ Screw-in the cap in clockwise direction (see tightening torques). ▶ We recommend a minimum clearance of 140 mm [5.51 inch] between filter and oil level. Commissioning For commissioning of the system, no...
