The 4000 series half mask can be disassembled in less than a minute. This allows for quick and easy cleaning. The ergonomic and modern design offers greater user comfort and a more secure fit. The support harness is attached to the rigid body of the half mask, not to the facepiece, therefore it does not mark the user’s face. The bayonet fitting system provides a quick and safe filter attachment. The facepiece is available in thermoplastic rubber or silicone rubber.


  • Adjustable harness provides optimal fit for all
  • Design provides compatibility with safety glasses
  • Silicone face seal provides comfort and stability
  • Easy to dismantle and clean in seconds
