3M 7000005397 Papr Sar Headgear Prefilter

Product Description

The 3M 7000005397 is a prefilter accessory designed for use with the W-2806 Filter and Regulator Panel in powered air-purifying respirator (PAPR) and supplied-air respirator (SAR) headgear systems. This component provides an additional filtration stage ahead of the main filter assembly, helping to extend the service life of downstream filter media by capturing larger particulates before they reach the primary filter. Installation and replacement are handled by safety equipment technicians or industrial hygiene personnel responsible for maintaining respiratory protection programs. The unit ships as a single piece and weighs 2.9 pounds.

This prefilter is intended for use in industrial, construction, and hazardous-material environments where PAPR or SAR headgear systems are deployed. It fits specifically within the W-2806 Filter and Regulator Panel assembly and is suited for applications requiring continuous respiratory protection, such as spray finishing, abrasive blasting, or work in atmospheres with airborne particulates. Replacement frequency depends on particulate loading and environmental conditions at the jobsite.

Installation Notes

Prefilter replacement should be performed by trained personnel following the respiratory protection program procedures established at the facility. Always shut down airflow to the PAPR or SAR unit before removing or installing filter components. Consult the W-2806 system documentation for correct seating and retention procedures. Follow applicable OSHA respiratory protection standards and facility safety protocols during service.
