Professional MSA 3S PS AutoMaXX full face respirator mask with polycarbonate lens, AutoMaXX plug connection, and positive pressure capability. Offers superior comfort, large field of vision, and quick donning system. Over 5 million units sold worldwide.
The MSA 3S PS MaXX Positive Pressure Full Face Mask with AutoMaXX Plug Connection represents the most successful mask design in the world, with over 5 million units sold globally. This professional-grade respirator offers exceptional comfort, value, and efficiency for users requiring respiratory protection in hazardous environments. The mask features an impact-resistant polycarbonate lens that provides users with an enhanced field of vision, while an optional inner mask ensures optimal airflow, prevents lens fogging, and reduces dead space effectively.
The face blank is constructed from a special rubber compound that creates a softer, more comfortable seal that remains unaffected by lotions or creams. Combined with a deeper chin stop design, this ensures a snug and secure fit for all users. A clamped connector within the face blank houses the AutoMaXX plug connection, inhalation valve, and speech diaphragm, which permits excellent communication during use. The 3S-PS-MaXX version is specifically designed for use with positive pressure lung-governed valves for both compressed air breathing apparatus and compressed airline breathing apparatus.
The mask incorporates a harness system that allows for quick donning and removal without requiring adjustments, providing a pressure-free fit with a carrying strap that enables the mask to be carried in front of the chest for immediate accessibility. The exhalation valve is positioned at the lowest point of the respirator, featuring a low exhalation resistance due to the mask's large cross-section. Both the valve disc and valve cover are easily replaceable for maintenance and longevity. Available in multiple versions with various harness options and lens materials to suit different industrial applications and requirements.
