General Description
The extraction fan is used for extracting harmful fumes and gases
which are released during the most common welding processes.
The extraction fan is part of a welding fume extraction system
with extraction arms, hoods, downdraft tables, etc. that are
connected to a central filter system type.
The choice of the most appropriate type of extraction fan depends
on the number of extraction arms to be connected, the pressure
drop in the entire system, combined with the local regulations
and/or the specific application.
proDuct combinations
The fan is intended to be used in the following configurations:
-- multiple arm systems
-- modular extraction hood systems
-- push-pull systems
components
The extraction fan is a centrifugal fan with straight blades. The
inlet is on the side; the outlet is on top. The fan consists of the
following main components and features:
A extraction fan
B inlet opening with adapter
C outlet opening with adapter

Extraction fan can either be placed on the floor or on a frame.
Make sure the frame is strong enough to carry the weight of the
fan. A construction drawing of an appropriate frame can be
obtained with your supplier.
In case the fan is not placed directly next to the central filter
system, make sure the connection duct is sufficiently
supported.
The SF Series fan can optionally be equipped with a silencer.
In case of a silencer:
1) Mount the silencer on the outlet of the fan.
In case the silencer is to be connected to an outlet
duct:
2) Connect the second reducer metric-standard to the silencer.
3) Connect the appropriate outlet duct to the reducer.
4) Make sure all connections are airtight.
In case no silencer is involved:
5) Connect the second reducer metric-standard to the outlet
of the fan.
6) Connect the appropriate outlet duct to the reducer.
7) Make sure all connections are airtight.
