235673-36 - Miller PAPR HEPA Filter Replacement Cartridge Bulk Pack (36-Count)

Industrial-Grade Respiratory Protection Management

The Miller 235673-36 is a bulk inventory solution designed for industrial facilities utilizing Miller Powered Air Purifying Respirator (PAPR) systems. This package contains thirty-six (36) individual HEPA filters, identified by the base part number 235673. These filters are the primary line of defense in the Miller PAPR blower unit, engineered to provide High-Efficiency Particulate Air filtration. The media is rated to capture 99.97% of airborne particles down to 0.3 microns in size, making it highly effective against the complex mixture of metal oxides, silicates, and fluorides found in welding fumes.

In heavy manufacturing and fabrication environments, maintaining a consistent supply of consumables is critical to operational continuity and regulatory compliance. The 235673 filter is specifically constructed to trap hazardous particulates such as hexavalent chromium, manganese, zinc oxide, and steel dust, which are common byproducts of SMAW, GMAW, and FCAW processes. The pleated design of the filter media increases the total surface area, allowing for a higher particulate holding capacity while maintaining the necessary airflow rates required to keep the PAPR system functioning within its design parameters (typically 6+ CFM).

Regular replacement of the main HEPA filter is dictated by the saturation level of the media, often indicated by the PAPR blower's flow alarm or a noticeable reduction in air supply. By procuring these filters in the 36-count bulk configuration, facility managers and safety officers can streamline procurement cycles and ensure that individual welding stations are never left without necessary protection. These filters are compatible with standard Miller PAPR blower assemblies often paired with Titanium 9400i or T94i-R helmets. Proper storage in a dry, climate-controlled environment will ensure the shelf life and integrity of the filter media until deployment.
