RE 51413/02.09
Design
FEF 0, FEF 1:
Combination of flange-on filling filter (screen basket 500 μm)
and cap removable via bayonet lock as breather with internal
filter element 40 μm. The filter element must be exchanged together with the cap. The breather cap is secured against loss
by means of a chain.
Materials as per spare parts list.
BFS 7…, BFS 20…:
Compact housing for ventilation with pleated filter element of
paper.
Materials as per spare parts list.
