3M Half Face Reuseable Respirator, 4000 Series


The 4000 Series Respirators are a unique range of ready-to-use, maintenance-free half face respirators.

The built-in filters are integral to the mould providing comfortable protection against a combination of many gases, vapours and particulate hazards. Utilising the unique filter technology enables a low-profile, well balanced design for an undisturbed field of view.  Meets the performance requirements of AS/NZS 1716:2012.

Features and Benefits:

  • Lightweight, well balanced design
  • Soft, non-allergenic face seal
  • Textured face seal to minimise slippage and improve comfort
  • Built-in filters - No cartridge or filter replacement required
  • Four versions available, each offering protection against different hazards
  • One piece, maintenance-free design
  • Unique wrap around design provides an undisturbed field of view
  • Use until damaged, particulate filters clog or gas filters become saturated
  • Re-sealable bag provides convenient and clean storage between uses
  • Ideal for contractors, plant shutdowns and spill response (eliminates need for separate respirator, cartridge/filter or carrying out respirator maintenance)
