DA 1200 wall inlet

1 Product description
Wall inlet DA 1200 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 Advanced inlet control 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.
The inlet is easy-to-clean due to its open and smooth construction. Also, the thermoplastic stands high-pressure
cleaning. Furthermore, the choice of material makes the inlet resistant to UV radiation. The inlet is made of high-
impact material; it is dimensionally stable and 100% recyclable.

ments. The inlet can be assembled from modules in a number of different
ways. The inlet shutter is insulated.
The inlet is supplied with regulation set and parts for Advanced Inlet Con-
trol.
2.2 Accessories
433016 DA 1200 net, fine 10x10 mm
The net for DA 1211/1211B is ordered separately. Fine net prevents the
ingress of mice and rats.
Net size 10x10 mm. Self-supporting, but it is recommendable to fasten it
with screws if used together with the extension.
Fine net reduces inlet capacity by approx. 10 %.
One per inlet.

433015 DA net, coarse 65x20 mm
The net for DA 1211/1211B is ordered separately.
Net size 65x20 mm. Self-supporting, but it is recommendable to fasten it
with screws if used together with the extension.
Coarse net does not reduce the inlet capacity.
One per inlet.
433022 DA 1200 set w. screws x10 for block
Used for assembly of DA 1200 inlets where these are to be mounted in
blocks. Includes 40 5x45 mm stainless screws.
One set for each 10 inlets.
433117 DA 1211/1911 net holder set for 25 inlets
The net holder is used for mounting the net when mounting is required on
the outer wall instead of directly on the inlet, for example, at deep window
openings.
Contains 100 pcs.
One set for each 25 inlets.
433112 DA 1200 air direction baffle, short
The air direction baffle is 7.5 cm. Air direction baffle (short/long) can be
used for adjusting the air jet under cold weather conditions and to avoid ad-
hesion on the wall. The baffle is used for all inlets. However, in connection
with 2 rows of inlets the baffle is only required for the top row if the inlets
are placed right above each other.
One per inlet or one for every second inlet.
433114 DA 1200 air direction baffle, long incl. side plate
The air direction baffle is 15 cm and includes side plates. Air direction baffle
(short/long) can be used for adjusting the air jet under cold weather condi-
tions and to avoid adhesion on the wall. The baffle is used for all inlets.
However, in connection with 2 rows of inlets the baffle is only required for
the top row if the inlets are placed right above each other.
Long air direction baffle is applied where the air jet range and Coanda-ef-
fect are particular important, for instance in wide livestock houses.
One per inlet or one for every second inlet.
560195 DA 1200 regulation set w. long U-shackle
Used where obstacles such as lopsided walls, steel trusses projecting up to
70 mm out from the wall, etc. impede the free movement of the pull rod.
The current system of Advanced inlet control cannot be used with the kit
and therefore an extra string with spring to reduce the slack is included by
which you can make Advanced inlet control.
The inlet flap should as a maximum open to a horizontal position; otherwise
it may overload the winch motor.
One per inlet.

433039 DA 1200 extension piece 240 mm
S433037B DA 1200 extension piece 400 mm, type B
The extension rod is used if you want to run the pull rod round heavy con-
crete pillars or the like, where it is not possible to run the pull rod directly
through the pillar by making a through-going hole. The extension rod is
made of stainless steel.
One per inlet.
401902 DA 1000/1200 single operation set
If individual operation of each inlet is required, DA 1200 single operation
set is mounted.
One per inlet.
401935 Carrier roller f. pull rod, built-in inlet
Is used for built-in inlets.
If the distance between the inlets exceeds approx. 2 m, the pull rod will
bend downwards causing inaccuracies if carrier rollers are not used.
One unit for each 2 meters free-hanging pull rod.
401349 All-purpose holder for pull rod
If the distance between the inlets exceeds 2 m, the pull rod will bend down-
wards causing inaccuracies if all-purpose holders are not used.
One unit for each 2 meters free-hanging pull rod.
433021 DA 1200 regulation set for 2 inlets
DA 1200 regulation set for 2 inlets at different heights.
A pull rod row for each row of inlets is preferred and using 433021 should
therefore be regarded as a cheaper alternative.
One for each inlet in the upper row.
413214 LPV door set for pull rod 8 mm
If there are doors or the like in the wall where the inlets are mounted and
you temporarily want to end the pull rod, a special kit containing the neces-
sary parts can be acquired. The kit makes it possible to manually maintain
correct ventilation level and easily reestablish the pull rod.
One per door.

433014 DA 1200 baffle plate
For reduction of external actions on the DA 1200 or DA 1211/1211B, baffle
plates are offered in connection with one or more of the following condi-
tions:
• The volume of the livestock house is low (narrow and low livestock
house with a flat ceiling)
• In detached wind-affected buildings without windbreaks 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.
One per inlet.
413223 Door set for wire tension
The mounting set is used where the pull rod is directed along the door
frame by means of wire and reels.
One per door.
433064 DA 1200 light trap complete
Used for DA 1200 brick-in wall inlet if dimming of light 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).
One per inlet.
433067 DA 1200 outside flange
The flange is included in 433064 but can also be mounted on the outside in
connection with DA 1211/1211B flange inlets to
• increase the output to the same level as DA 1200. Correct the number of
inlets, if needed.
• make a nicer finish on the outside of the building and the net can subse-
quently be mounted on the flange.
• give a broader covering than 433281
433067 can be used when the lateral distance between the inlets is more
than 5 cm.
One per inlet.
433066 DA 1200 light trap ex. flange
Used for retrofitting on DA 1200/1211/1211B 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).
One per inlet.

433155 DA 1200 inlet cover
DA 1200 inlet cover can be used together with the inlets of the DA 1200 se-
ries.
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.
One per wall inlet.
433312 DA 1200 light trap for inlet cover
DA 1200 light trap for inlet is always used together with DA 1200 inlet
cover.
The light trap prevents a large amount of daylight from seeping into the
building ("brown out"). The light trap is made of injection-molded PP
(polypropylene) which is dirt-repellent and easy to clean.
Use one for each DA 1200 inlet cover.
433334 DA 1200 fly screen
DA 1200 fly screen for inlet cover is always used together with DA 1200 in-
let cover.
The fly screen prevents the ingress of flies and the screen is self-support-
ing.
Can only be used for inlets in 1 row.
With regular and sufficient cleaning, the capacity of the inlet is not reduced
by the use of the fly screen.
One 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 bypass in case the
fly screen is choked.
Use 1 m2 fly screen per 2000 m3/h max. air.
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.
Screw kit (560333) is ordered separately.
560333 Screw kit DA 1200/1911 hen net
The screw kit is used to mount the hen net.
1 set per hen net.
