FUME EXTRACTION ARMS
General Description
The extraction arms have been specially designed for extracting
harmful fumes and gasses which are released during the most
common welding processes. Thanks to the patented construction
and the unique principle of the rotating of the hood the extraction
arm is easily maneuverable which enables constant adaptation of
LFA
the working reach to the specific requirements of the user.
Lincoln's LFA extraction arms are spring-balanced for easy
positioning. They are intended for use with a low-vacuum, high-
volume extraction fan. The LFA arms are commonly installed on a
Mobiflex ® 200-M or 400-MS mobile base unit with filter or with an
SF2400 Wall-Mounted Extraction Fan, with or without a Statiflex
LTA
200-M or 400-MS Wall-Mounted Filter Unit.
Lincoln's LTA 2.0 fume extraction arms telescope 3-5 ft. long,
making them ideal for small workstation or booth applications.
They are intended for use with a low-vacuum, high-volume
extraction fan.
The telescopic arm is commonly installed with a SF2400 Wall-
mounted Fan. Extracted air can be vented outside through the Air
Exhaust Silencer, or filtered through a Statiflex 200-M or 400-MS
Wall-Mounted Filter Unit. The Starter/Overload Switch for the
SF2400 Extraction Fan protects the motor against overcurrent.
The optional Arc Sensor/LampKit for Wall-Mounted Systems
provides a work lamp and remote, hood-mounted switches for the
lamp and extraction fan, replacing the starter/overload switch.
