Transverse Adapter and Inlet Nozzles
Technical Data
Issued: 04/2017

Inlet Nozzles
For isokinetic microbiological air samplings in external air flows, e.g. in air
ducts, inlet nozzles are available to adapt the nominal flow rate of the sam-
pling head to the one of the sample air.
The flow rate of the sample air has to be measured with a flow meter to
determine the required inlet nozzle from the table above.
The cleaned inlet nozzle is mounted on the inlet pipe of the transverse
adapter. The sealing is provided by an O-ring on the shaft of the inlet noz-
zle. When using MBASS30 as air-conveying device, make sure that the
outgoing air is flowing in the same direction as the sample air.

Applications
The transverse adapter is an optional accessory for the air sampling
heads LKS 30 and LKS100 and allows to draw in the sample air hor-
izontally. Additionally, isokinetic microbiological air samplings and
the loading of PU foam cylinders for chemical air samplings are
possible. The transverse adapter is used instead of the top part of
the air sampling head.
Components
The transverse adapter consists of the adapter head and the inlet pipe. The
inlet pipe gets screwed into the adapter head and can be unmounted for
cleaning. Only screw on the transverse adapter hand-tight. The sealing is
provided by a gasket on the pipe.
Loading of PU Foam Cylinders
PU foam cylinders with a diameter of 50 mm and a length of 50 to
70 mm can be loaded for chemical air samplings. Up to two PU
foam cylinders can be inserted behind each other in the pipe. When
operating with MBASS30, 300 liters of sample air should be drawn prior
to the sampling without a PU foam cylinder for acclimation. The sampling
procedure is described in the relevant guidelines (e.g. DIN I O 16000 parts
12 and 13).
Remark hen using the air sampling head LKS100:
The air sampling head LKS100 has a much lower air
resistance than the LKS 30 when operating at
30 l/min to load o PU foam cylinder. Depending on
the resistance of the PU foam cylinder, this may lead
to the error message ”No sampler active”. By placing
the included 55 mm circular filter onto the jet plate,
the air resistance of LKS100 can be adjusted.
Remarks hen using MBASS30 as air-conveying device:
The usage of a binderless glass fiber filter is not possible due to its high flow
resistance. Manual checking of the air flow before and after the sampling,
as required by some guidelines, is not possible.
