1 General
This user’s guide is meant for the installer and for the
end user. It’s a reference to operaon and installaon of
an SR-AMC air curtain. For safety sake and to guarantee
correct operaon, it is essenalthat you read this manu-
al thoroughly before starng the installaon, including all
ps and warnings.
Keep this manual with the appliance and see to it that it is
included when the appliance is moved or
sold, to ensure that everyone is informed about the use
and safety aspects of the device throughout its
lifeme.

The Air Curtain Module consists of a metal casing with
a bladed fan and motor on top, secured by a fan guard.
There is a discharge nozzle with louvers on the opposite
side, which enables the airow to be directed in the de-
sired direcon. An air curtain consist of mulple Air Cur-
tain Modules with an assembly set.

The air curtain funcons as an invisible door/segregaon
and has insulaon properes, this can reduce energy loss-
es up to 80% with an open door. The air curtain can be
used with chilled or heated spaces. In most circumstances
an air curtain is used to minimise heat losses with an open
door, it could also be used as a segregaon between a non
or limited heated space and warmer heated space.
For example between a storage space and workshop.
The airspeed can be controlled by an oponal 5 stage
speed controller, which can be used to adjust airspeed for
dierent heights (widths), dierence in forced venlaon
(negave pressure) within the building or for variaon in
weather inuences. The switch has a stage that cuts o
power to the installaon. (stage 0).
The air curtain can be acvated through the use of a door
switch, which triggers a relay which in turn sends the
power to the air curtain.
1.3 Warranty
Operaon/installaon of appliances not according to this
manual will void the warranty. It’s not allowed to change
the specicaons or to make modicaons of any kind, on
this appliance.
2 Technical Data
2.1 Table with data
Because the SR-AMC air curtain consist of mulple modu-
lar secons, a variaon of dierent widths or heights (ver-
cal installaon) can be constructed. Theorecal there
isn’t a limit to the amount of coupled modules, but every
10 connected modules must be succoured/supported at
each end.
If more than 10 modules are used there needs to be a
another power source, because the internal
wiring is designed for a maximum amperage of 10A.

2.2 Pre-check
Before installaon, please check (i.e. on the data badge)
if the appliance is in accordance with the order and
whether it suites the local and present provisions (
electrical supply etc.). Also check aer installaon that
operaon of the appliance can’t form any hazard caused
by moisture and dust, or can cause injuries to people.

3.1 Suspension
Every unit has 4 ‘pop nuts’ at each corner, in the illus-
traon on page 3, the dimensions are depicted with the
nocaon H-H.
By using these ‘pop nuts’ one can mount the air curtain
to the wall or ceiling with brackets or M10 studs. These
are not included (as standard).
The coupled modules have to be suspended or sup-
ported at each end. The maximum non-supported or
suspended coupled units is set at 10 modules (5m) to
prevent sagging.

Each module is 500mm long. One can nd the number of
modules with resulng length in the data table on page
3.
The air curtain has to be wider than the door opening to
provide an eecve barrier and prevent air ingress at the
ends (see Fig.2).
 Measure the width of the door in cm and
divide with 50, the resulng number is the minimum
number of modules. Almost always there is an extra
module needed for sucient overlap.

Make sure the air curtain has undisrupted ow of intake
air and blown air, there should be a minimum distance of
0.5m between ceiling or overhead door.
Horizontal mounng is preferred above vercal mount-
ing, as this enables the air curtain to also serve as a
recirculaon fan and the air stream will be warmer than
on oor level.
The side of the air stream should be as close as possi-
ble to the edge of the door opening, the further the air
curtain is placed away from the door opening the less
eecve it becomes.
The distance to the wall with our horizontal brackets is
variable between 41-368mm, with the vercal brackets
this is between 0-300mm.
The maximum mounng height is 4.5m. In case of
vercal mounng the maximum door width for one air
curtain is 4.5m. For other dimensions ask your supplier
for advice.
With use of the adjustable louvres, one can change the
direcon of the air stream, the louvres may not be set at
extreme angles, because this has a negave eect on the
eciency of the fans.

Warning: Before starng installaon make sure that
that electrical group you are working on, has been shut
o. The appliance must be earthed.
4.1 230Vac supply
The installaon must comply with all applicable local
and/or naonal standards i.e. NEN 1010.
There should be a suitable electrical group with a main
fuse. There is an electrical diagram further on in this
guide.
The electrical supply is 230Vac (50 Hz) with earth.

The appliance has to be equipped with a 230 Volt isola-
on switch or power plug. This switch should be suitable
for the maximum accumulated amperage. This switch
should disconnect phase and neutral (not earth) and
have at least an 3mm contact opening.
Switches or power plugs must be accessible at all mes.
For power supply the unit has been provided with a
3-pole power plug (female). The installer should connect
a 3-wire mains cable and a power plug to it.

With the interference of an isolaon switch or power
plug the air curtain can be connected to the mains. If the
connecon is made the fans will run connually at full
speed. See sect6.2

The air curtain can be acvated as the door opens. This
can be done with the use of a door switch, which powers
the relay of the relay box (arcle GA4100) and acvates
the air curtain. See sect6.3.

dierent heights (widths), dierence in forced venlaon

The 5-stage speed control is installed in between the
power source. Depending on the chosen stage, the fan
will turn fast or slowly.
Before installaon consult the manual of the 5-stages
switch. See sect6.2 and 6.3.

Warning: Before starng maintenance make sure that


With the 5-step switch one can adjust the airspeed on
ground level, as explained in sect4.2.
The airspeed on ground level should not be too low
otherwise the air curtain coverage cannot withstand any
wind load. Too high airspeed at ground level will lead to
unnecessary turbulence and excessive sound. The ideal
ow prole is depicted in the illustraon below (Fig. 5),
one can roughly check this by feeling with the hands, or
‘tu tesng’ with a strip of paper to visualise the airow
prole. Of course an anemometer would be best. If there
is a strong wind load on the door opening, one can turn
up the airspeed.
The air curtain isolates the interior space, thus it can be
used in summer. Not only to repel the heat , but also to
prevent the ingress of ying insects.
Aenon: Do not set the louvers in an (sloping) angle
greater than 20°. This will decrease the air output.

5.2 Maintenance
In spaces with heavy dust it might be necessary to clean
the fan guard with compressed air once a year. If the
fan guard is covered with severe dust the fan will have
diminished sucon capabilies.
