235674 - Miller T94 PAPR Foam Pre-Filter Replacement (6-Pack)

Miller 235674 PAPR Foam Pre-filter (6-Pack)

Maintaining the integrity and efficiency of your Personal Air Purifying Respirator (PAPR) system is critical for safety in industrial welding environments. The Miller 235674 Foam Pre-filter is a vital component designed specifically for the Miller T94-R, T94i-R, and Gen 2 Face Shield PAPR systems. This pre-filter serves as the first line of defense in your respiratory protection setup, engineered to capture larger airborne particulates, grinding dust, and debris before they can reach the main filtration unit.

By effectively trapping coarse contaminants, the foam pre-filter plays a crucial role in extending the service life of the more expensive main HEPA filter. Without a functioning pre-filter, the main filter would rapidly become clogged with large particles, reducing airflow and necessitating frequent, costly replacements. The 235674 pre-filter ensures that the HEPA filter can focus on its primary job: filtering out fine, hazardous welding fumes and sub-micron particles. This staged filtration approach optimizes the overall performance of the PAPR blower unit, maintaining consistent airflow and reducing strain on the motor.

These pre-filters are manufactured from high-quality, porous foam that balances filtration efficiency with low breathing resistance. They are designed for easy installation, fitting snugly into the filter assembly of the T94 series PAPR units. Regular inspection and replacement of the pre-filter are recommended to ensure maximum protection and system longevity. In heavy fabrication environments where grinding and high-amperage welding create significant particulate matter, the pre-filter is an indispensable consumable.

This product comes in a convenient package of six, allowing facility managers and welders to keep a ready supply on hand for routine maintenance. Using genuine Miller Electric replacement parts guarantees compatibility and maintains the NIOSH certification of the respirator system. Whether you are operating in a shipyard, heavy equipment manufacturing, or structural steel fabrication, the Miller 235674 pre-filter is a small investment that yields significant savings in long-term equipment maintenance and filter costs.
