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.
Consisting of a hood, facepiece with lens housing, breathing tube, lens cartridge, flow-control device, air-supply hose and support belt, the Abrasi-Blast Respirator can be designed for diverse applications by varying individual components.
The Abrasi-Blast Respirator has the following NIOSH/MSHA approvals: " Approval TC-19C-161 for Abrasi-Blast Respirator when used with 8 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 8 to 300 ft. of MSA Air-Supply Hose at an inlet pressure of 35 to 40 psig. " Approval TC-19C-178 (cool only) for Abrasi-Blast Respirator with vortex tubes. " Approval TC-19C-236 for Abrasi-Blast Pressure-Demand Respirator. " Duo Flow Abrasi Blast - see NIOSH Approved Matrix, PN 818148

Designed to be used in toxic atmospheres not immediately dangerous to life or health as defined in 30 CFR, Part 11. The respirator is available with a belt-mounted, pressure-demand regulator with quick-disconnect assembly, web belt and either a full facepiece or half-mask facepiece connected by a flexible breathing tube. Applications include welding, painting and handling certain hazardous materials.
These respirators are designed to maintain a slight positive pressure of air inside the facepiece whether the wearer is inhaling or exhaling. This helps prevent contaminants from seeping in around the facepiece, even if there should be small breaks in the face-to-facepiece seal.

The MSA Pressure-Demand Air-line Respirator has received National Institute for Occupational Safety and Health (NIOSH) and Mine Safety and Health Administration (MSHA) Certification No. TC-19C-158, for use in atmospheres not immediately dangerous to life and health and from which the wearer cannot escape without the aid of a respirator. MSA Air-Supply Hose (25-300 feet) must be used to maintain NIOSH/MSHA certification. The units require an air supply from an uncontaminated compressed-air source as stipulated in General Industry Safety and Health Regulations, Part 1910.134 (OSHA) with the delivered air conforming to at least Grade D of ANSI Standard Z86.1.

The complete respirator assembly is available with either an Ultravue or Ultra Elite full-facepiece, Comfo half-mask facepiece or Comfo welder's facepiece, breathing tube, web support belt and air flow control valve with quick-disconnect assembly. The constant flow respirator is used in non-IDLH environments.
Constant Flow Air-Line Respirators are designed to maintain a slight positive pressure of air inside the facepiece whether the wearer is inhaling or exhaling. This helps prevent contaminants from seeping in around the facepiece, even if there should be small breaks in the face-to-facepiece seal.
The MSA Constant Flow Air-line Respirators have received National Institute for Occupational Safety and Health (NIOSH) certification for use in atmospheres not immediately dangerous to life and health. The approval requires use of the proper length of air-supply hose and the proper air source. Units having an inlet pressure range of 10-15 psig are covered by Approval TC-19C-113 when used with 8-50 feet of MSA Air-Supply Hose; units having an inlet pressure range of 35-40 psig are covered by Approval TC-19C-78 when used with 8-300 feet of MSA Air-Supply Hose. The respirator requires a source of compressed air conforming to at least Grade D Compressed Gas Association, Inc., Commodity Specification for Air, G-7.1. When connected to an appropriate air supply, the respirator delivers a continous supply of breathable air and simultaneously provides a cooling effect.
