this welding downdraft table is designed to help
collect and recycle shop air that is contaminated
with many types of welding dust, oily smoke, and
fumes. however, it is not designed as a substitute
or "single-solution" for a respirator or fresh-air
type respirator. often metals have coatings that
produce poisonous fumes when heated, so make
sure that you are familiar with the materials to be
welded and you know what types of fumes will
be produced. Keep your shop in compliance with
oSha welding safety requirements at all times.
this fume extractor can be permanently connected
to a welding workstation downdraft table, or
wheeled to various welding locations.
a squirrel-cage type fan located inside of the fume
extractor cabinet draws welding sparks, dust,
smoke, and fumes through the snorkel. then the
contaminated air passes through a slag drawer
that is fitted with two 1mm stainless steel screens
that arrest sparks and collect minor welding slag.
periodically the operator must pull this drawer
open to remove the collected material.
From the slag drawer, the air now enters the next
chamber where a 10-micron paper roller-type
filter collects the coarse welding dust and the oily
smoke. at an adjustable interval, this paper filter
automatically advances to always provide new
filtration paper before it becomes caked and CFM
is lost.
With the air now vacant of oily smoke and 85%
of the welding dust, the air passes through a
dual 1-micron pleated paper-type filter where the
remainder of the dust is collected. at an adjustable
interval, this filter element is vibrated automatically
to prevent caking. any caked material then falls
into the removable dust drawer.
at this point, the air passes through the a final
filter. this pleated hEpa filter removes the rest
of the 1-micron particles and 99.97% of the 0.3-
micron particles. the recycled air now reenters
the shop.
