1. Description
The Weller WFE 2S is a volume fume extraction system ideally suited to a continuous
industrial operation environment. (it is not suitable for use as a tip extraction system.)
A powerful, maintenance free turbine combined with a digital electronic speed control
system ensures ease of use and low maintenance costs. The digital electronic speed
control system provides air movement which is continuously variable from 30 m
to 230 m
3
/h. Two DN 40 intake flanges are fitted to the top of the unit for connection
to pipe work systems. The WFE 2S is fitted with a three stage filter system, pre filter
(F5), sub micron filter (H13) and wide band gas filter, specifically designed to deal
with solder fumes. In its delivered state this filter system ensures a degree of
separation of 99.95 % i.a.w to DIN 24184 for a particle size of 0.3 µm. The differential
pressure inside the unit is measured constantly and a red LED display is illuminated
when the unit senses that a filter change is required. Under normal running conditions
a green light is displayed. The system can be controlled manually at the unit or
remotely via an RS 232 interface. An hours run counter and a speed limiting control
are available as optional extras.
