MOBIFLEX 400-MS BASE UNIT
The K1741-1 Mobiflex 400-MS Base Unit is a mobile
filter unit with integrated fan that provides extraction
and filtration for use with a flexible extraction arm or
optional hose.
The Mobiflex 400-MS Base Unit features a steel mesh
prefilter and a round cellulose LongLife filter cartridge.
This LongLife filter cartridge is provided with a precoat
(ExtraCoat) to extend the lifespan and increase initial
operating efficiency of the filter.
The Mobiflex 400-MS Base Unit is provided with a
RotaPulse system for automatic cleaning of the
LongLife filter cartridge.
The Mobiflex 400-MS is a portable unit suitable to be
used in relatively small facilities or near sources of pol-
lution without a fixed location.
The Mobiflex 400-MS Base Unit with Flexible
Extraction Arm is used for extracting and filtering fume
which is released during the most common welding
processes, such as:
• MIG/MAG solid wire (GMAW)
• MIG/MAG flux cored wire (FCAW)
• TIG (GTAW) welding
• Stick welding (MMA or SMAW)
• Autogeneous welding
The Mobiflex 400-MS is designed for intermittent or
continuous welding applications as indicated above.
The Mobiflex 400-MS filter is recommended for annual
consumable use of approximately:
• 6,000 lbs (2,750 kg) GMAW or FCAW or GTAW
• 4,000 lbs (1,800 kg) MMA or SMAW or autoge-
neous
Variables such as coatings (e.g. oil), base material,
weld process, humidity and procedures can affect filter
life and performance.
MOBIFLEX 400-MS/HE BASE UNIT
The K1741-2 Mobiflex 400-MS/HE Base Unit is a
mobile filter unit with integrated fan that provides
extraction and filtration for use with a flexible extraction
arm or optional hose.
The Mobiflex 400-MS/HE Base Unit features a steel
mesh prefilter and a high efficiency round
cellulose/polyester blend LongLife filter cartridge.
The Mobiflex 400-MS/HE Base Unit is provided with a
RotaPulse system for automatic cleaning of the
LongLife filter cartridge.
The Mobiflex 400-MS/HE is a portable unit suitable to
be used in relatively small facilities or near sources of
pollution without a fixed location.
The Mobiflex 400-MS/HE Base Unit with Flexible
Extraction Arm is used for extracting and filtering fume
which is released during the most common welding
processes, such as:
• MIG/MAG solid wire (GMAW)
• MIG/MAG flux cored wire (FCAW)
• TIG (GTAW) welding
• Stick welding (MMA or SMAW)
• Autogeneous welding
The Mobiflex 400-MS/HE is designed for intermittent or
continuous welding applications as indicated above.
The Mobiflex 400-MS/HE filter is recommended for
annual consumable use of approximately:
• 550 lbs (250 kg) GMAW or FCAW or GTAW
• 385 lbs (175 kg) MMA or SMAW or autogeneous
Variables such as coatings (e.g. oil), base material,
weld process, humidity and procedures can affect filter
life and performance.
