Increased Ease-Of-Use
We’ve eliminated those time-consuming filter
fastener screws! Now you simply snap-off the
helmet’s front panel and squeeze two locking tabs
together to quickly remove the filter cassette.
Changing the inner and outer protective filter
plates has never been
easier or faster!
Speedglas helmet 9000 construction: Note the
aerodynamic exhaust vents that are located directly
behind the front silver panel. The patented helmet
is extremely comfortable, weighing only 17.4
ounces (including filter) and has excellent balance.
Its narrow width is ideal for welding in tight spots.
The polyamide nylon construction is heat and
chemical resistant and extremely durable.

FILTERS AND HELMETS
The revolutionary 3M
Speedglas
Helmet 9000
features patented aerodynamic exhaust vents that
help to remove exhaled air.
Welders experience lower humidity, less heat, and
reduced “stuffiness.” The welder’s natural
breathing action directs the exhaust airflow; no
moving parts are involved. Fresh, incoming air is
not drawn through the special vents; instead, it
chooses the path of least resistance—the area
around the welder’s neck, which is typically further
away from the smoke plume.
A Welding Helmet
that Breathes!
Exhaled air is directed through the four aerodynamic
vents. It then exhausts through two thin openings
created between the double-shell construction of the
heat-reflecting silver front panel and the black helmet.
