The fume extraction unit WFE 8S can be connected to up to 8 extraction arms. This makes the unit suitable to use as a small central system in applications such as soldering, adhesives, clean-room work and laser work. It is also capable for connection to small, selective reflow and soldering ovens. The large integrated pre-filter makes the WFE 8S very suitable for lead-free soldering as it is able to catch a large quantity of particles. The WFE 8S is a mobile system that is simple to install – it does not require any permanent installation. Its high quality components keep service needs to a minimum. The combination of low running costs and a flexible system independent of fixed installations produces a unit with a very low cost of ownership. WFE 8S can be connected so that it exhausts air. This is an advantage in applications where re-circulation is not allowed. To further increase the filter lifetime and save energy, the WFE 8S has an automatic airflow control - depending on the number of connected workplaces.
