- the drain channel arrangement 17 is formed, which has two horizontal channel channels 17a arranged one above the other and a vertical outlet channel 17b.
- the respective channel channel 17a is aligned horizontally in the built-in ventilation device with a deviation of up to 10 ° to the ground in order to be able to guide the water separated in the filter element 3 horizontally in the outlet channel arrangement 17 under the action of gravity.
- the respective channel channel 17a connects the drip regions 4b of the housing 4 of the ventilation modules 2 in the stack block 19 which are adjacent in series.
- the two channel channels 17a are vertically fluidically connected via the outlet channel 17b.
- the vertical drainage channel 17b is vertically aligned in the built-in aeration device 1 with a deviation of up to 10 ° to the ground, so that the water deposited in the filter element 3 is directed from the upper channel channel 17a to the lower channel channel 17a under the action of gravity can.
- the water separated in the filter elements 3 is then conducted out of the drain channel arrangement 17 into the collecting area 11b of the flow adapter 11 and further outwards.
- the lower channel channel 17a at its deepest Stel le through the drain opening 28 with the collecting area 11 b of the flow adapter ters fluidly connected.
