3.2 Installation examples
Inspect the building in relation to the drawing, paying attention to the position of DA 60-820, roof pitch and roof
type.
3.2.1 Placement
If the fresh air is coming from the open, the inlet must
be placed above the ridge to minimize the external im-
pact of the air inlet.
If the roof pitch is less than 20°, this is not necessary.
DA 60-820 can also distribute the air coming from the
attic space, when an adequate opening area has been
ensured to the attic.
0.9 - 1.0 m
Min. 0.5m
In flat-ceiling livestock houses, the DA 60-820 should be
placed as close to the ceiling as possible.
In flat-ceiling livestock houses, the exhaust unit is
placed minimum 0.5 m under DA 60-820, if possible, to
reduce the risk of direct shortcut of air between the two
units.

Place DA 60-820 as follows in livestock houses with a
sloping ceiling:
F

D
.
F
is diviced by 60% to
C
.
Make sure to comply with the distance requirement of at
least 1.5 m from the edge of the outlet funnel and hori-
zontally to the ceiling. Otherwise it could give rise to
problems regarding to excessive air velocities in the ani-
mal zone.

H
4 m
If the height difference to the ceiling at a distance of 4
m from DA 60-820 is:
H
≤ 1.2 m, it should be dimensioned as an adhesive
air jet
H
> 1.2 m, it should be dimensioned as free air direc-
tion
As a general rule, SKOV recommends a placement so
that the air is distributed as an adhesive jet.
