The 3M Robust Comfort Half Mask has been designed for dirty and demanding work environments. It is available with a 3M Quick-Release drop-down mechanism. The 3M Quick-Release system allows the mask to be put on and taken off quickly when entering or leaving a hazardous area, without having to remove a helmet or face shield. The mask, available in three sizes, is fitted with the 3M Bayonet Click filter connection. This allows the use of a wide range of 3M filters to protect against gases, vapours and particles, depending on the user’s needs. Size: M
