Helmet 9000 HWR
The NIOSH-approved supplied air (SA) 9000 system provides
respiratory protection from airborne particulates and gases. The
lightweight, belt-mounted valves permit the
welder to adjust the temperature of the air
entering the headpiece ±45°, making it
ideal for very hot or strenuous
jobs.
Note: Because faceshields and welding shields can be raised from the
normal position ANSI Z87.1-2003 states that safety spectacles or
goggles must be used in conjunction with these respirators.
