287170-36 - Miller 287170-36 HEPA Filter Bulk Pack for PAPR & PAPR II

Technical Overview of Miller 287170-36 HEPA Filters

The Miller 287170-36 is a bulk package containing thirty-six (36) High Efficiency Particulate Air (HEPA) filters designed specifically for the Miller Powered Air Purifying Respirator (PAPR) systems. These filters serve as the primary line of defense in industrial respiratory protection setups, engineered to interface seamlessly with both the legacy Miller PAPR blower motors and the updated PAPR II blower assemblies. As a direct NIOSH-approved replacement for the discontinued Miller 235673-36 filter, this SKU ensures continued compliance and safety for facilities utilizing Miller's air-purifying technologies.

Technically, the filter media is constructed to capture airborne particulates with an efficiency of 99.97% down to a size of 0.3 microns. This level of filtration is critical in welding and metal fabrication environments where operators are exposed to hazardous contaminants such as hexavalent chromium, manganese, zinc oxide, and other metallic fumes generated during the welding process. The filter's pleated design maximizes surface area, allowing for optimal airflow rates required by the blower unit while maintaining high particle retention. This balance prevents the blower motor from overworking, thereby extending the battery life and longevity of the PAPR unit itself.

For procurement and inventory management, the 36-pack configuration (SKU 287170-36) offers a logistical advantage for large-scale operations. By consolidating consumables into a larger unit of measure, facilities can reduce administrative overhead associated with frequent purchasing cycles. It is imperative that these filters are stored in a dry, climate-controlled environment to maintain their electrostatic and mechanical filtration properties prior to use. Users should note that these are particulate filters only and do not provide protection against gases or vapors unless used in conjunction with appropriate chemical cartridges, where applicable and supported by the specific PAPR configuration.
