GENERAL DESCRIPTION
The MINIFLEX
®
is a portable, high vacuum welding fume extractor
designed for the removal and filtration of welding fumes from light
duty welding applications. Its compact size permits the MINIFLEX to
be used in confined spaces and other locations that are not
accessible with other welding fume extractors.
The convenient automatic start/stop function can extend the life of the
motor brushes and reduces energy consumption. (Note: welding
current must be at least 50 amps to activate sensor). The optional
wall mounting bracket allows the unit to be mounted to a wall, freeing
up floor space.
The MINIFLEX can be completely disassembled in a matter of minutes
for cleaning and maintenance.
