this portable fume extractor helps collect and
recycle shop air that is contaminated with welding
dust, oily smoke, and fumes. however, it is not
designed to be the "single-solution" air cleaner
and should not substitute respirator or fresh-air
type respirator use. often metals have coatings
that produce very poisonous fumes when heated,
so make sure that you are familiar with the types
of fumes produced by the material that you are
welding. Keep your shop in compliance with
oshA welding safety requirements at all times.
the Model h8375 can be permanently connected
to a small welding downdraft table or moved to
various welding locations. two squirrel-cage fans
are located inside of the cabinet and draw welding
dust, smoke, and fumes through the suction hood
and then through a series of filters before the air
re-enters the shop. this filtration occurs in the fol-
lowing five stages:
Stage 1
Contaminated air enters the machine through a
slag catch tray, and then through a 1-2mm stain-
less steel screen that arrests sparks, and collects
minor welding slag.
Stage 2
Considered the first consumable pleated filter, this
filter collects 35% of the 2-10 micron welding dust
and most of the oily smoke.
Stage 3
the second consumable pleated filter catches
85% of the 1-2 micron dust and the remaining oily
smoke.
Stage 4
this serviceable-type pleated filter, catches 45%
of the 1-micron size particles.
Stage 5
this hepA filter catches 99.97% of the 0.3-micron
dust particles before the recycled air finally exits
the machine and reenters the shop.
