OPT4160.500 - Optrel Swiss Air Replacement Half Mask - Black

Technical Overview of the Optrel Swiss Air Replacement Mask

The Optrel 4160.500 is the designated replacement half mask for the Swiss Air Powered Air-Purifying Respirator (PAPR) system. Engineered to maintain the system's TH3 certification, this component is critical for ensuring the positive pressure seal required to protect operators from particulate matter, fumes, and aerosols in industrial environments. The mask is constructed from high-grade, flame-retardant ripstop textile, offering both durability against sparks and spatter, and flexibility for a contour-conforming fit.

This assembly includes the textile mask body and the essential nose foam element. The design facilitates a clear separation between the breathing zone and the ambient environment, directing clean airflow directly to the user's nose and mouth while efficiently managing exhalation. The material selection prioritizes skin compatibility and moisture management, reducing the risk of dermatitis during prolonged shifts. The mechanical interface allows for rapid detachment from the Y-hose assembly, simplifying the cleaning and maintenance protocols mandated by safety standards.

By replacing the half mask at regular intervals or when signs of wear appear, facilities ensure that the Swiss Air system continues to deliver its rated protection factor (APF). The low-profile geometry of the mask is specifically calibrated to fit underneath virtually any welding helmet or face shield without creating pressure points or obstructing the visual field. This SKU serves as a direct OEM replacement, guaranteeing perfect compatibility with the existing blower and harness setup.
