951800 - Miller SAR System with T94i-R Helmet, C50 Regulator & 25ft Straight Hose

Complete Supplied Air Respiratory Protection

The Miller 951800 SAR (Supplied Air Respirator) System is a comprehensive safety solution designed for industrial welding environments requiring Grade D breathing air. This package pairs the advanced T94i-R™ auto-darkening welding helmet with the C50™ air regulator and a 25-foot straight air hose, providing a robust defense against hazardous fumes including hexavalent chromium, manganese, and zinc oxide. The system is engineered to meet strict NIOSH standards when used with a compatible air source, ensuring compliance and operator safety in manufacturing and fabrication settings.

Advanced Optical Performance

At the core of the T94i-R helmet is Miller's ClearLight™ Lens Technology, which optimizes contrast and clarity in both light and welding states. The lens assembly offers a substantial 9-square-inch viewing area, supported by four independent arc sensors for reliable arc detection. The digital lens interface allows for precise control over four distinct operating modes: Weld (Shades 8-13), Cut (Shades 5-8), Grind (Shade 3), and X-Mode. X-Mode utilizes electromagnetic sensing to detect the arc, making it ideal for outdoor work or obstructed views where optical sensors might fail. With a switching speed of 1/20,000 second, the lens provides immediate protection upon arc initiation.

Thermal Management and Ergonomics

The included C50 air regulator is a critical component for heat stress management, capable of cooling incoming air by up to 50 degrees Fahrenheit (28°C). The patent-pending Dualtec™ manifold system distributes this cooled air through a six-point airflow system, maximizing perceived cooling and preventing lens fogging. The helmet itself features a matte silver shell and an aluminum heat shield to reflect radiant heat, protecting both the digital lens and the user. The lightweight, low-profile design, coupled with a padded belt and integrated shoulder straps, ensures weight is evenly distributed to alleviate lower back strain during extended use.

System Connectivity and Durability

The 25-foot straight air hose (3/8 inch ID) comes equipped with 1/4 inch industrial interchange fittings and a 360-degree swivel connection to prevent coiling and reduce trip hazards. The breathing tube is protected by a flame-resistant cover to withstand sparks and abrasion. This system is designed for loose-fitting supplied air applications and does not require fit testing, although it must not be used in IDLH (Immediately Dangerous to Life or Health) environments.
