Weight and Design
Constructed out of synthetic components, the Miniflex is light-
weight, at only 36 lbs. (16 kg), and impact resistant with a user-
friendly design. With wheels and handle standard, the Miniflex can
be easily rolled or carried around, unlike competitive models.
Five-Stage Filtration Process
The Miniflex has a five-stage filtration process. In stage one, as the
air enters the system through an intake connection, it passes
through a removable and washable metal pre-filter in which heavier
particles and foreign material are captured. In stage two, the air
passes through a second metal pre-separator to further reduce any
large particle matter from reaching the LongLife-H main filter. In
stage three, the air passes through the LongLife-H main filter where
the welding fume particles are captured and deposited. In an
optional stage four, after flowing through the LongLife-H filter, the
air passes through the optional activated carbon filter to help
prevent or neutralize the release of odors back into the
environment. In the final stage (stage five), the air passes through a
HEPA filter (also known as High Efficiency Particle Air).
LongLife-H filter
The unique design of the Miniflex's LongLife-H main filter has
resulted in a very large filter surface area equaling 130 ft2 (12 m2).
With such a large surface area, the filter has an extended life. The
LongLife-H filter is designed to dispose of extracted welding fume
deposits at the time of filter disposal, preventing deposits from
being released during welding.
Cable Sensor
At the top of the Miniflex unit is an automatic start/stop button and
a manual button. When the Miniflex is being operated in automatic
mode, the unit automatically switches on as welder begins to weld,
and automatically switches off approximately 15 seconds after
welder stops welding. The result is less energy consumption and
non-continuous noise. For the automatic start/stop function to
work, the welder’s work cable or power cable must be laid across
the top of the Miniflex unit in the slotted groove with an integrated
sensor.
When the Miniflex is being operated in manual mode, the unit is
continuously running.
Reduced Noise
Smart noise insulation around the air exhaust significantly reduces
noise without overheating the motors. 70dB(A) with nozzle
extraction installed.
Two Parallel Motors
The Miniflex is powered by two 1.2 hp motors allowing for sufficient
extraction capacity under all conditions. At the top of the Miniflex
unit is a high/low button. In high mode, both motors are working at
100% capacity, extracting 135 CFM of air. In low mode, both
motors are working at 50% capacity, extracting 94 CFM of air. With
both motors increasing and decreasing speed, the result is a
continuously balanced system with reduced maintenance. The
motors parallel positioning design reduces noise.
Automatic Start/Stop for
less energy consumption,
convenience and longer
filter life.
Wheels standard
for easy portability.
