- the flow adapter 11 is in one piece and preferably molded from plastic. As a result, the flow adapter 11 is robust and the air drawn in from the outside by the respective blower 5 is already distributed in the flow adapter 11 and flows uniformly over the respective filter elements 3.
- the flow adapter 11 has the flow region 11a and the collecting region 11b, connecting to each other.
- the flow area 11 a of the flow adapter 11 corresponds fluidly to the inlet openings 8 of the respective housings 4, and the collecting area 11 b is offset transversely to the flow direction 10 below the flow area 11 a. assigns. Further, the collecting portion 11 b is located outside a main air flow in the flow adapter 11th
- the drain channel arrangement 17 is formed in the coupling frame 14.
- the latter fluidly connects the collecting area 11b of the flow adapter 11 and the drip areas 4b of the respective housings 4 fluidically with one another.
- the drain channel arrangement 17 the water separated in the filter element 3 can be guided out of the respective housing 4 into the collecting area 17 of the flow adapter 11 in the opposite direction of flow 10.
- the collecting region 11b of the flow adapter 11 is fluidically connected to the drain channel arrangement 17 via a drain opening 28, the drain channel arrangement 17 being connected to the drain opening 28 at its lowest point in the lower gutter channel 17a via a drain line (not shown here) is.
- the water deposited in the filter elements 3 is led into the flow adapter 11 through the drain opening 28 and guided outward in the collecting area 11 b of the flow adapter 11 counter to the flow direction 10.
- the construction of the drainage channel arrangement 17 is shown in detail in FIGS. 6, 14 and 15.
- FIGS. 14 and 15 show sectional views of the ventilation device 1.
- the individual ventilation modules 2 to the stacking block 19 and, on the other side, the flow adapter 11 are fixed on one side to the coupling frame 14.
- 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 each because the drip areas 4b of the adjacent housing 4 of the ventilation modules 2 in the stack block 19 are connected 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 is fluidically connected at its lowest point by the discharge opening 28 with the collecting area 11b of the flow adapter.
- the plurality of housing 4 and the plurality of filter elements 3 via the drain channel assembly 17 in the coupling frame 14 are fluidly connected to each other and the separated in the plurality of filter elements 3 water can be easily derived from the ventilation device 1.
- the ventilating device 1 can be modularly constructed and the identically designed ventilation modules 2 can be easily exchanged for one another; Furthermore, the water separated in the respective filter element 3 can be diverted from the ventilation device 1 in a simplified manner; A sealing of the ventilation device 1 can be simplified and the ventilation device 1 can be controlled more accurately and the air flow in the respective filter element 3 can be better distributed.
