Allegro 9350-03 Papr Sar Filtration Panels Prefilter

Product Description

The ALLEGRO 9350-03 is a prefilter accessory designed for use with PAPR (Powered Air-Purifying Respirator) and SAR (Supplied Air Respirator) headgear filtration panel systems. This component extends the service life of primary filtration panels by capturing larger particulates before they reach the main filter media. It is sized and configured to integrate directly with compatible ALLEGRO filtration panel assemblies. Safety professionals, industrial hygienists, and respirator maintenance technicians typically specify and install these prefilters as part of a scheduled respirator maintenance program. The unit ships in a single-piece package quantity.

This prefilter accessory is suited for industrial and occupational environments where PAPR and SAR respiratory protection is required. Typical applications include manufacturing facilities, chemical processing plants, construction sites, and other worksites where airborne particulate hazards are present. It is used during routine maintenance intervals to protect and extend the primary filtration media within the headgear assembly. Personnel responsible for respiratory protection program compliance will incorporate this component into their replacement schedules per applicable OSHA and ANSI Z88 guidelines.

Installation Notes

Installation and replacement of respirator prefilter accessories should be performed by a qualified respirator program administrator or trained safety technician following the manufacturer's instructions. Always don and doff respiratory protection in a clean area away from the contaminated work zone. Ensure the primary PAPR or SAR unit is fully powered down and disconnected from the air supply before servicing any filter components. Follow your facility's written respiratory protection program and applicable OSHA 29 CFR 1910.134 requirements for filter change-out schedules.
