247471 - Miller Titanium 9400i PAPR Replacement Shell Assembly (No Lens)

Miller 247471 Helmet Assembly for Titanium 9400i PAPR

The Miller 247471 is a specialized replacement helmet assembly designed exclusively for the Miller Titanium 9400i PAPR (Powered Air Purifying Respirator) system. This product serves as a direct replacement for a damaged or worn-out helmet shell, ensuring that your respiratory protection system maintains its integrity and comfort without the need to purchase a completely new helmet kit. It is important to note that this assembly is the shell only; it does not include the auto-darkening lens (ADF), the headgear suspension, or the PAPR blower unit itself. It is intended for users who already own the 9400i PAPR system and need to swap out the outer protective housing.

Constructed with Miller's signature aluminum heat shield technology, this silver shell is engineered to reflect radiant heat, keeping the welder significantly cooler than traditional black helmets. This feature is particularly critical for high-amperage welding applications where heat buildup can cause fatigue and discomfort. The shell features the 9400i's renowned flip-up design, which integrates a clear grinding shield underneath the welding lens assembly. This allows the operator to switch seamlessly between welding and grinding tasks without removing the helmet or breaking the positive pressure seal essential for PAPR safety.

Maintaining the condition of your PAPR helmet shell is vital for safety. Cracks or severe damage to the shell can compromise the positive pressure environment required to keep fumes and particulates out of the breathing zone. The Miller 247471 ensures that your equipment meets factory specifications for safety and fit. The lightweight design minimizes neck strain, making it suitable for all-day wear in industrial environments. By offering the shell as a standalone component, Miller provides a cost-effective maintenance solution for professional welders.

This assembly is compatible with the specific ducting and seals used in the Miller PAPR systems. It is not a standard passive helmet shell but is engineered to facilitate proper airflow from the blower unit over the user's face. Whether your original shell has been damaged by impact or excessive spatter, the 247471 restores your gear to optimal working condition.
