 MSA Constant-Flow Abrasi-Blast™ Supplied-Air Respirator
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.
The constant flow model is approved for use in atmospheres not immediately dangerous to life or health and operates through one of three flow-control devices: adjustable, non-adjustable or a vortex tube. These versions incorporate the Quick-disconnect fitting with the flow-control device.
During blasting operations, the lens of the Abrasi-Blast Respirator is protected by 2 to 4 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. There is no need to stop to change lenses, as is necessary with most conventional blastinghoods. Approved by NIOSH.
*Complete Assemblies include Hypalon Hood, 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, facepiece (medium) with dual exhalation valves and lens housing, breathing tube, web belt, and air-hose connector.
