ESD safe low sound level
WFE 4S
Mobile fume extraction unit purifies
air up to 8 soldering workplaces
The fume extraction system WFE 4S is user-
friendly with quick and simple installation and
filter exchange. It has a low noise emission
level and is small and convenient to locate
within the work area.
The high quality components used in the
WFE 4S result in low servicing requirements
and long system life. To increase filter lifetime
and save on energy, the WFE 4S is fitted with
an automatic airflow speed control - depending
on the number of connected workplaces. To
extend the capacity an external pre-filter can
be fixed directly to the WFE 4S.
The powerful maintenance free variable speed
turbine is electronically controlled and has a
maximum capacity of 615 m3/h. It has 3 opera-
ting modes:
1. Standard speed control – selected by the user
irrespective of the load on the system.
2. Speed limiting control – the pump speed is
automatically varied to match the load on
the system.
3. Economy control – the rate of fume
absorption is maintained at a constant value.
The operating hours and the filter condition
are recorded for maintenance purposes.

The pre-filter is recommended for use with solder bath,
automatic soldering, laser or other major dust emitting
applications. It acts as a first stage in the filter process
increasing the lifetime of the main filter units. The pre-
filter can be fixed directly to the top of the WFE 4S or in
conjunction with the WFE 2S and WFE 2X as an external
part of the fume extraction system.
