Scott Health & Safety’s easy breathing 742 series twin cartridges were developed to provide optimal respiratory protection in non-IDLH industrial or HAZMAT situations. The 742 cartridges are designed with a low profile, swept back cartridge to ensure optimal field of vision and allows use of communications. The 742 series is available in a full range of NIOSH approved, chemical cartridges or combination cartridges. With Scott’s “Top-Down” convertibility the 742 cartridges attach directly to XCEL Halfmask and Promask full facepiece. Industrial Safety offers the 742 cartridges with the ¼ turn adapters for use with the AV-2000 and the AV-3000 masks.
