Lincoln Electric’s
®
Mobiflex
™
400-MS is a portable, low vacuum/high volume self-cleaning filtration
system designed for heavy duty extraction and filtration of welding fumes.
The lightweight and rugged design of the Mobiflex
™
400-MS along with the standard front caster and
rear wheels allows for easy portability. It is ideal for facilities that require welding fume extraction in
multiple locations, including maintenance departments, general fabrication and job shops, and industrial
welding environments. Because of the self-cleaning function, the Mobiflex
™
400-MS can also be used in
production environments where welding duty cycles are longer and more frequent.
The Mobiflex
™
400-MS can be configured with Lincoln’s LFA 3.1 or LFA 4.1
fume extraction arms or with the 152 mm (6") diameter, 5 m (16’) long flexible
hose and hood set. Lincoln Electric’s
®
fume extraction arms are designed to
provide welders optimal motion and reach for their specific welding position(s)
and work area. The arm lengths range from 3.1 m (10 ft.) to 4.1 m
(13 ft.). For hard to reach areas such as confined spaces, the flexible hose
and set can be easily carried to locations where an extraction arm just is not
feasible.
The internal extraction fan is designed specifically for weld applications.
It extracts weld fume through the arm, into the internal spark arrestor and
finally through the self-cleaning filter cartridge capturing the welding fume
particulate. As the particulate is collected on the outside of the filter cartridge
and builds up, the filter is then automatically cleaned causing the particulate
to fall into the collection bin for easy, hands free disposal.
The Mobiflex
™
400-MS filter is recommended for consumable use of approximately
6,000 lbs.(2722 kg) of MIG wire or 4,000 lbs. (1814 kg) of stick or flux-cored wire before replacing.
Filter performance will be affected by process and application variables including:
base metal(s), consumables(s), and coatings (oil) if applicable.
