The Advantage 4000 Abrasi-Blast Respirator, new from MSA Safety Works, provides respiratory and upper body protection during abrasive blasting for workers in shipbuilding, the construction industry, utilities and other industries.

The respirator can be configured for diverse applications by varying individual components.

Components and Approvals

The Advantage 4000 consists of a durable hood, facepiece with lens housing, breathing tube, lens cartridge, flow-control device, air-supply hose and support belt. MSA says the air-line respirator is the only one of its type with CE-approval for tight-fitting facepieces.

MSA Advantage 4000 respirator

Advantage 4000 Abrasi-Blast Respirators can be modified through model and component selection for diverse blasting operations and can be used with MSA’s new Breathing Air Distribution System (BRADS) models.

The Abrasi-Blast Respirator has the following NIOSH approvals:

  • Approval TC-19C-161 for Abrasi-Blast Respirator when used with eight to 50 ft. of MSA Air-Supply Hose at an inlet pressure of 10 to 15 psig.
  • Approval TC-19C-162 for Abrasi-Blast Respirator when used with eight to 300 ft. of MSA Air-Supply Hose at an inlet pressure of 35 to 40 psig.
  • Duo Flow Abrasi-Blast: See NIOSH Approved Matrix, PN 818148.

Lenses and Assemblies

During blasting operations, the Abrasi-Blast lens is protected by two to four flat glass cover lenses mounted in a special foam material. Each cover lens can be removed by integral pull tabs when it becomes abraded, eliminating the need to stop and change lenses.

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 with socket assembly, medium facepiece with dual-exhalation valves and lens housing, breathing tube, web-belt and air-hose connector.
