GENERAL DESCRIPTION
This instruction manual describes two base units and
four types of extraction arms:
• K1653-2 Mobiflex 200-M Base Unit (mobile filter
unit with disposable filter cartridge - filter class MERV
11 (untreated); MERV 14 (treated))
• K1653-3 Mobiflex 200-M/HE Base Unit (mobile filter
unit with high efficiency disposable filter cartridge - fil-
ter class MERV 16)
• K2633-1 LFA 3.1 Mobile Manual (10 ft. extraction
arm)
• K2633-3 LFA 4.1 Mobile Manual (13 ft. extraction
arm)
• K2633-2 LFA 3.1 Mobile Automatic (10 ft. extrac-
tion arm with integrated Lamp & Arc Sensor Kit)
• K2633-4 LFA 4.1 Mobile Automatic (13 ft. extrac-
tion arm with integrated Lamp & Arc Sensor Kit)
MOBIFLEX 200-M BASE UNIT
The K1653-2 Mobiflex 200-M Base Unit is a mobile fil-
ter unit with integrated fan that provides extraction and
filtration for use with a flexible extraction arm or option-
al hose.
The Mobiflex 200-M Base Unit features an aluminum
prefilter and a square disposable cellulose LongLife fil-
ter cartridge. This LongLife filter cartridge is provided
with a precoat (ExtraCoat) to extend the lifespan and
increase initial operating efficiency of the filter. A sep-
arate MSDS sheet for the ExtraCoat is included with
the instruction manual package.
The Mobiflex 200-M is a portable unit suitable to be
used in relatively small facilities or near sources of pol-
lution without a fixed location.
The Mobiflex 200-M 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 200-M is designed for lighter to medium
duty, intermittent welding applications as indicated
above.
MOBIFLEX 200-M(/HE) MOBILE FILTER UNIT & LFA 3.1 / 4.1 EXTRACTION UNIT
OPERATION
The Mobiflex 200-M filter is recommended for annual
consumable use of approximately*:
• 1,500 lbs (700 kg) GMAW or FCAW or GTAW
• 1,100 lbs (500 kg) MMA or SMAW or autoge-
neous
* Variables such as coatings (e.g. oil), base material,
weld process, humidity and procedures can affect fil-
ter life and performance.
MOBIFLEX 200-M/HE BASE UNIT
The K1653-3 Mobiflex 200-M/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 200-M/HE Base Unit features an alu-
minum prefilter and a high efficiency square dispos-
able cellulose/polyester blend LongLife filter cartridge.
The Mobiflex 200-M/HE is a portable unit suitable to be
used in relatively small facilities or near sources of pol-
lution without a fixed location.
The Mobiflex 200-M/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 200-M/HE is designed for lighter to medi-
um duty, intermittent welding applications as indicated
above.
The Mobiflex 200-M/HE filter is recommended for
annual consumable use of approximately*:
• 500 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 and procedures can affect filter life and
performance.
