Product Information :
The Abrasi-Blast respirator provides
respiratory and upper body protection for workers in
shipbuilding, the construction industry, utilities and other
applications where blasting with abrasives is performed. A
complete Abrasi-Blast respirator is made up of a hood, facepiece
with lens housing, breathing tube, cover lens cartridge
assembly, flow-control device, approved air-supply hose and
support belt. During blasting operations, the lens of the Abrasi-Blast
respirator is protected by two to four flat glass cover lenses
mounted in a special foam material. Each cover lens is removed
by integral pull tabs when it becomes so abraded that vision is
reduced, eliminating the need to stop and change lenses, as is
necessary with most conventional blasting hoods. Complete
assemblies include one lens cartridge consisting of four
0.06-inch untempered glass cover lenses, flow-control device,
Snap-Tite aluminum quick-disconnect fitting, adjustable
valve-connector body or pressure-demand regulator (with socket
assembly), facepiece (medium) with dual-exhalation valves and
lens housing, breathing tube, web-belt and air-hose connector.
