Function principle
Air volume from the ground
RS100 has a 50 m hose on
the pressure side which can
be positioned freely up to
till 50 m away from the wall
lead-in.
The extraction points in
the concrete slab must
be positioned centrally
where the air below the
concrete slab is warmest
and not at outside walls.
In order for the radon level in the house to be reduced the air pressure under the
concrete slab must be lower than that in the house. Because the house often
stands on very compact fill material it is necessary to have an installation which has
an extremely large suction capacity. To achieve this, radon extractor RS100 is con-
nected to a pipe system that sucks up an air/radon mixture from the air pockets
under the concrete slab. The dirt particles that follow in the airflow remain in the
filter that is directly inside the inlet connector on the suction side (filter hatch) in
RS100. When the air/radon mix has passed RS100 it is blown out to the surrounding
air through a silencer and wall lead-in. The installation is designed and constructed
for continuous operation.
Flow resistance in the fill material under
the concrete slab
The “tri-coloured” curve indicates the air volu-
me/flow resistance which is also based on the
Corromatic meter on the RS100 radon extractor.
At an air volume of 50m3/h the flow resistance
is 5000 Pa (corresponds to 0.05 kg/cm2).
NOTE! During operation, the air volume meter
must be within the green zone up to 85 m3/h.
The energy consumption is usually 200-250 W.
Installed output 370 W.
