3.1 Degree of Protection
IP40
3.2 Emissions
CAUTION
C4.0050
Possibility of acoustic signals not being heard
Loud suction noises
Possible acoustic alarms and voice communication might not be heard.
•Consider the volume of the suction noises in relation to other
acoustic signals in the work environment. Additional visual signals
may be used.
CAUTION
C5.0046
Hearing damage
Due to suction noises at the suction opening a high sound level may be
generated
Excessive noise in terms of level and duration can cause impairments or
permanent damage to hearing.
•Ensure suitable noise protection measures are taken or wear ear
protection.
Sound parameters:
The AS 200 jet itself causes, due to its construction, almost no significant noise emission.
The sound parameters of the connected industrial vacuum cleaner depend on the set suction
power.
Example:
Industrial vacuum cleaner:
Nilfisk HDS 2000
Suction level:
2
At these operating conditions, the workplace related equivalent continuous sound level
Leq = 72 dB(A).
3.3 Electromagnetic Compatibility (EMC)
EMC class according to DIN EN 55011: B
3.4 Rated Power
~ 50 W (VA)
The rated power of the AS 200 jet including an industrial vacuum cleaner (e.g. Nilfisk HDS
2000) amounts max. 1 450 W (VA).

Height with test sieve (50 mm): ~ 382 mm
Width: 460 mm
Width with cyclone separator: ~ 665 mm
Depth: 302 mm
Depth with manual vacuum regulation: ~ 392 mm
Depth with automatic vacuum regulation: ~ 418 mm
Weight: ~ 16 kg
3.6 Required Floor Space
CAUTION
C6.0047
Falling down of the device
Incorrect positioning or insufficient working space
Due to its weight, the device can inflict personal injury if it falls down.
•The device must only be operated on a sufficiently large, strong and
stable workplace.
•All feet of the device must be positioned securely.
Width of the base: 480 mm
680 mm (with cyclone separator)
Depth of the base: 460 mm
No safety clearances required
Location requirements:
The device must be placed on a vibration-free, plane, stable and free surface to avoid
transmission of vibrations. A level base ensures the uniform distribution of the sample over the
sieve mesh fabric, as well as the stability of the device.
3.7 Receptacle Volume
The maximum receptacle volume (the maximum feed quantity) depends on various factors such
as aperture size of the test sieve, maximum grain size and width of distribution of the sample
material.
Examples for the maximum feed quantity according to DIN 66165 for test sieves of 200 mm in
diameter are listed in the following table:

3.8 Feed Grain Size
Traditional dry sieving is performed in the particle size range of 40 µm to 125 mm. By means of
sieving aids or with wet sieving the measurement range can be extended to 20 µm. The
maximum feed grain size depends on the sample material, the number and aperture size of the
test sieves and the type of the sieving machine.
Examples for the maximum feed grain size according to DIN 66165 are listed in the following
table:

3.9 Negative Pressure
NOTICE The maximum negative pressure, generated by an industrial vacuum cleaner or an
external suction device must be < 100 mbar (10 000 Pa or 1.45 psi)!
3.10 Payload
Depending on the mesh size of the test sieve used (Chapter "Receptacle Volume") and the
density of the sample material, the maximum payload is 0.3 –100 g.
NOTICE If the test sieve is overloaded, it can be damaged as the sample material clogs the
meshes and the negative pressure can thus exert too much force on the sieve mesh fabric.
3.11 Suitable Sieve Diameters
Suitable sieve diameters: 200 mm / 203 mm (8")

Suction of objects
Suction opening of the silencer
Smaller objects can be sucked into the interior of the device.
•Make sure that no objects are placed near the suction opening.
To generate the necessary negative pressure in the nozzle chamber, the AS 200 jet sucks the
required air through the silencer (F) during operation.
Make sure that the suction opening of the silencer is always kept clear and that the air can
be sucked in unhindered!

Danger to life through electric shock
Damaged power cable
An electric shock can cause burns, cardiac arrhythmia, respiratory arrest,
as well as cardiac arrest.
•Never use a damaged power cable to connect the device to the
mains!
•Check the power cable and the plug for any damage before use.
NOTICE
N11.0002
Setting up the device
Disconnecting the device from the mains
A separation of the device from the mains must be possible at any time.
•Set up the device in such a way, that the connection for the power
cable is always easily accessible.
Before first commissioning the silencer and the manual or automatic vacuum regulation must be
installed, and an industrial vacuum cleaner must be connected.
Subsequently, the desired test sieve with the appropriate lid can be inserted. The AS 200 jet is
suitable for test sieves with an outer diameter of 200 mm (with adapter ring) and 203 mm.
NOTICE Only one test sieve must be inserted. A large amount of sample can significantly
increase the load on the sieve mesh fabric. Make sure not to exceed the maximum payload
(Chapter "Payload").
5.1 Silencer
To reduce the suction noise, it is recommended to mount the silencer (F) included in the
delivery to the air inlet duct (D).

5.2.1 Connecting the Manual Vacuum Regulation
Fig. 5: Mounting the manual vacuum regulation
Insert the manual vacuum regulation (G) into the air outlet duct (E).
5.2.2 Adjustment of the Manual Vacuum Regulation
The manual vacuum regulation (G) has a lateral opening (G2) through which air is sucked in.
The size of the opening can be varied by means of a slider (G1). This allows to adjust the
desired negative pressure in the nozzle chamber (A).
When the opening is closed (1), the airflow from the nozzle (B) and thus also the negative
pressure in the nozzle chamber is at maximum. With the opening at maximum (4), the airflow
from the nozzle and thus the negative pressure in the nozzle chamber is at a minimum.
In between, the negative pressure can be infinitely adjusted by means of the slider (G1).
