Weller WFE 2X Operating Instructions Manual Download

Page: 6 / 12

Thank you for placing your trust in our company by purcha-
sing the Weller WFE 2X volume fume extraction unit.
Production was based on stringent quality requirements
which guarantee the perfect operation of the device.

1. Caution!

Please read these Operating Instructions and the attached
safety information carefully prior to initial operation. Failure
to observe the safety regulations results in a risk to life and
limb.

The manufacturer shall not be liable for damage resulting
from misuse of the machine or unauthorised alterations.

The Weller WFE 2X volume fume extraction system extrac-
tion unit corresponds to the EC Declaration of Conformity in
accordance with the basic safety requirements of Directives
2004/108/EC and 2006/95/EC.

WFE 2X is a mobile filter unit for cleaning of both particles
and gases. The unit are used for filtration of process air from
soldering, gluing, cleaning, printing processes etcetera.

2. Description

The Weller WFE 2X is a volume fume extraction system ide-
ally suited to a continuous industrial operation environment.
(it is not suitable for use as a tip extraction system.) A power-
ful, maintenance free turbine combined with a digital elec-
tronic speed control system ensures ease of use and low
maintenance costs. The digital electronic speed control
system provides air movement which is continuously varia-
ble from 30 m

/h to 230 m

/h. Two DN 60 intake flanges are

fitted to the top of the unit for connection to pipe work
systems. The WFE 2X is fitted with a two stage filter system,
a sub micron filter (H13) and wide band gas filter, specifical-
ly 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 EN 1822 for a particle size of 0.12 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 remote interface.

The unit must not be exposed to temperatures exceeding
50° C, open flames or condensated solvents.

Switch off the filter unit when changing filter.

3. Commissioning

The best possible gas filtration will be achieved if:
- Process air temperature in the gas filter < 38 °C
- Relative humidity < 60 %
- Gas molecules > 30 g / mol (filtration better with larger

molecules)

- Boiling temperature of gas molecules > 0 °C

NOTE!

The unit may dust some from the main filter after
transportation. Make sure the starting of the unit is made in
an appropriate room.
Place the filter system on the floor or hang it on the
workbench with mounting device, art no 005 36 575 99.
Connect the power cord and switch the circuit breaker.

Installation

Fit one or both DN 60 connection flanges to the filter hou-
sing. If only one connecting flange is to be used then the
other vacuum connection must remain blanked. The con-
necting flanges can be connected either directly to a DN 60
pipe system or via a flexible pipe to the fume collection devi-
ce. Ensure that the exhaust air from the WFE 2X is not
obstructed.

Electrical connection

The supply voltage must be checked against the machine
name plate details prior to switch on.
