WFE 4S Mobile fume extraction unit purifies air at up to eight soldering workstations


The WFE 4S fume extraction system is userfriendly 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 workstations. 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 operating 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.
WFE 4S includes:

Pre-filter to extend capacity of
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.

Pre-filter includes:
Filter box
(2) hose connections 75
