PRODUCT DESCRIPTION
DA 1200 wall inlet is a universal wall inlet which is used for ventilating livestock houses with natural,
LPV or Combi-Tunnel ventilation.
The DA 1200 inlet can be built directly into a wall without any additional support, or it can be embedded
directly in prefab elements at factories manufacturing such elements. The inlet can be assembled from
modules in a number of different ways. The wall inlet is available in different widths making it suitable
for wall thicknesses of up to 35 cm. The inlet is available either with a coarse or a fine mesh.
The universal differentiation of the inlets is patent pending and is supplied with a regulation set which
makes it easy to adjust the air inlet in accordance with the current conditions.
DA 1200 is easy-to-clean due to its open and smooth construction. Also, the thermoplastic stands high-
pressure cleaning. Furthermore, the choice of material (polystyrene) makes the inlet resistant to UV
radiation. The inlet is made of high-impact material; it is dimensionally stable and 100% recyclable.

DA 1200 is for building in or casting in prefab elements. The
inlet is sufficiently rugged to endure installation directly in
the wall without additional support. Furthermore it can be
incorporated directly in prefab elements during the casting
process. The wall inlet can be assembled from modules in
several different ways. The inlet shutter is insulated.
The wall inlet is supplied with regulation set and universal AIC.

433016 DA 1200 net, fine 10x10
A fine net protects against invasion of animals such as mice
and rats.
Net size = 10 × 10 mm. The net is self-supporting, but it is
recommended to fasten it with screws when used together
with an extension duct.
Fine net reduces inlet capacity by approx. 10 %.
1 unit per inlet.
3
433015 DA 1200 net coarse 65x20
Net size = 65 × 20 mm. The net is self-supporting, but it is
recommended to fasten it with screws when used together
with an extension duct.
Coarse net does not reduce the inlet capacity.
1 pc per inlet.

433022 DA 1200 set w.screws x10 for block
Used for assembly of DA 1200 brick-in inlets where these are
to be mounted in blocks. Includes 40 units 5 × 45 mm
rustproof screws.
1 set per 10 inlets.
5
433112 DA 1200 air direction baffle, short
The air direction baffle is 7.5cm long. An air direction baffle
(short/long) is always used for adjusting the air jet in cold
weather, and to prevent Coanda-effect along the wall. The
baffle is used on all inlets. However, with two rows of inlets,
it is only necessary with a baffle on the upper row, provided
the inlets are placed right above each other.
1 unit per inlet or 1 unit per every second inlet.
6
433114 DA 1200 air direction baffle, long w. side pl.
The air direction baffle is 15 cm long and with side plates. An
air direction baffle (short/long) is always used for adjusting
the air jet in cold weather, and to prevent Coanda-effect along
the wall. The baffle is used on all inlets. However, with two
rows of inlets, it is only necessary with a baffle on the upper
row, provided the inlets are placed right above each other.
The long air direction baffle is used where the air jet range
and the Coanda-effect are especially important, e.g. in wide
houses.
1 unit per inlet or 1 unit per every second inlet.
7
433014 DA 1200 baffle plate
For reduction of external actions on the DA 1200 baffle plates
are used when one or more of the following conditions are
current:
•The volume of the house is low (narrow and low with a
flat ceiling)
•In detached buildings without shelter belts and the like
The baffle plate must be mounted on all inlets in the same
room and are not to be used together with Advanced Inlet
Control.
The baffle plate increases the requirements to the tightness of
the building and cannot replace external windshield.
The baffle plate does not reduce the inlet capacity.
1 unit per inlet.

DA 1200 Wall Inlet

560195 DA 1200 operation set w. long U-shackle
Used where there are obstacles to the free movement of the
pull rod in the shape of disproportionate walls, steel rafters
etc., which project up to 70mm. The present differentiation
system cannot be used together with the set, for which reason
an extra line with spring is supplied to absorb slack. This
way, differentiation can be made.
The inlet flap is not to open more than to horizontal position,
as the winch motor may otherwise be overloaded.
1 unit per inlet.
9
433039 DA 1200 extension rod 240 mm
S433037B DA 1200 extension rod 400mm
Used where there are obstacles to the free movement of the
pull rod, which project more than 70mm from the wall. When
the extension rod is used, the pull rod lies 240/400 mm from
the wall, thus avoiding rafters, concrete poles and other
obstacles.
1 unit per inlet.
10
401902 DA 1000/1200 single operation set
When individual operation of each wall inlet is needed, the
DA 1200 single regulation set is mounted.
1 unit per inlet.
11
401935 Carrier roller f. pull rod, built-in inlet
Is used for built-in inlets.
If there are more than approx. 2 m between the inlets, the pull
rod will bend downwards causing inaccuracy if carrying
pulleys are not used.
1 unit by every 2 m free hanging pull rod.
12
401349 All-purpose holder for pull rod
Is used for flange inlets and built-in inlets.
If there are more than approx. 2 m between the inlets, the pull
rod will bend downwards causing inaccuracy if all-purpose
holders are not used.
1 unit by every 2 m free hanging pull rod.
13
433021 DA 1200 regulation set for 2 inlets
DA 1200 regulation set for two inlets in different heights.
One row of pull rods for each row of inlets is preferable, and
therefore the use of 433021 must be considered a cheaper
alternative.
1 unit per inlet in the upper row.

DA 1200 Wall Inlet
14
413214 LPV door set for pull rod 8mm
If there are doors etc. in the wall where the inlets are
mounted, and you want to disconnect the pull rod
temporarily, there is a special set that contains the necessary
parts. The set makes it possible to maintain the correct
ventilation level manually and to reassemble the pull rod
easily.
1 unit per door.
15
413223 Door set for wire
The mounting set is used if the pull rod is led round a door.
1 unit per door.
16
433064 DA 1200 light trap complete
Used for DA 1200 brick-in inlet if light dimming is required.
The light trap light-tightness is 99.9 %, corresponding to
20,000 lux outside and 0.05 lux inside (0.05 lux corresponds
to 2.5 ppm).
1 unit per inlet.
17
433067 DA 1200 outside flange
The flange is included in article no. 433064, but it can also be
mounted on the outside of houses with DA 1211/1211B inlets
in order to
•Increase the output to the same level as DA 1200.
Correct the number of inlets.
•Make a nicer finish on the outside of the building.
The net can be mounted on the flange afterwards.
•Give a broader flashing than 433281
433067 can be used when the distance between the inlets,
when placed side by side, exceeds 5 cm.
1 unit per inlet.
18
433066 DA 1200 light trap without flange
Used for retrofitting on DA 1200 when the flange is already
on the building and light dimming is required.
The light-tightness of the light trap is 99.9 %, corresponding
to 20,000 lux outside and 0.05 lux inside (0.05 lux
corresponds to 2.5 ppm).
1 unit per inlet.

DA 1200 Wall Inlet
19
433155 DA 1200 inlet cover
DA 1200 inlet cover can be used together with the inlets of
the DA 1200 series.
The inlet cover is designed to protect the livestock house
against rain/snow and to provide a certain amount of wind
and light dimming effect.
1 unit per inlet.
20
433312 DA 1200 light trap for inlet cover
DA 1200 light trap for inlet cover is always used with the DA
1200 inlet cover.
The light trap prevents a great deal of the sunlight from
penetrating into the building. The light trap is made of
injection-moulded PP (polypropylene) which is dirt-repellent
and easy to clean.
1 unit per DA 1200 inlet cover.
21
433334 DA 1200 fly screen
DA 1200 fly screen for inlet cover is always used together
with DA 1200 inlet cover.
The fly screen prevents the ingress of flies and the DA 1200
fly screen is self-supporting.
Can only be used for inlets in one row.
With regular and sufficient cleaning, the capacity of the inlet
is not reduced by the use of the fly screen.
1 unit per inlet.
433317 Fly screen - 25 m x 1.37 m
Fly screen on a roll prevents the ingress of flies.
With regular and sufficient cleaning there will be no
significant pressure loss, but an emergency opening should be
provided via by pass in case the fly screen is choked.
Use 1 m2fly screen per 2000 m3/h max. air.
22
433138 DA 1200 hen net, hinged
The hen net prevents the fledged hens from sitting in the air
inlet. The net is top-hinged, allowing easy access when
servicing the inlet.
The screw kit (560333) must be ordered separately.
560333 Screw kit DA 1200/1911 hen net
The screw kit is used to assemble the hen net.
One set per bird net.
