OVERVIEW

Technical Specification and Filtration Dynamics

The Miller 235673-6 HEPA Filter is a critical component for Miller Powered Air Purifying Respirator (PAPR) systems, engineered to meet stringent industrial hygiene standards. This high-efficiency particulate air (HEPA) filter is rated to capture at least 99.97% of airborne monodisperse particles with a diameter of 0.3 micrometers. This level of filtration is essential for environments where welding, gouging, and grinding operations generate fine particulate matter that can bypass standard filtration media.

In industrial fabrication settings, the composition of weld fumes varies based on the base metal and consumables used. This filter is specifically designed to mitigate the risks associated with hazardous elements often found in weld fumes, including hexavalent chromium, manganese, nickel, zinc, iron, copper, beryllium, lead, and cadmium. By effectively trapping these sub-micron particles, the filter ensures that the air delivered to the operator's breathing zone remains within safe permissible exposure limits (PELs).

The 235673-6 comes in a package of six, facilitating inventory management for safety officers and maintenance teams. Each filter is manufactured to precise tolerances to ensure a proper seal within the Miller PAPR blower unit, preventing bypass leakage. Regular replacement of the HEPA filter is necessary to maintain the system's assigned protection factor (APF) and to prevent strain on the blower motor caused by clogged media. The physical dimensions of the package are 6.00 inches in height, 8.00 inches in width, and 8.00 inches in length, with a total shipping weight of 1 lb 9 oz.

FAQ

These HEPA filters are rated to remove 99.97% of airborne particles at 0.3 micrometers in diameter.

This product (SKU 235673-6) contains a pack of 6 HEPA filters.

Yes, the HEPA filtration is effective at capturing particulates containing hexavalent chromium, as well as manganese, zinc, and lead.

It is designed for Miller Powered Air Purifying Respirators. Please check your specific blower unit manual for part number confirmation.

Filters should be replaced when the PAPR flow indicator signals low airflow, or if the filter is damaged or heavily soiled.

The package dimensions are approximately 8 inches long, 8 inches wide, and 6 inches high.

No, HEPA filters are disposable and should not be cleaned with compressed air or water, as this damages the filter media.

No, this is a particulate filter. It does not remove gases or vapors unless used in conjunction with a specific nuisance odor pre-filter if available for your unit.
