It mounts upstream of the main filter cartridge to capture larger airborne particles before they reach the primary filtration stage, extending the service life of downstream filter media. This prefilter is intended for environments where workers face particulate hazards such as dust, debris, or coarse aerosols. Installation and replacement are typically performed by safety personnel, industrial hygienists, or trained tradespeople responsible for maintaining respiratory protection equipment on the job site.\u003c\/p\u003e\u003cp\u003eThe 9350-04 prefilter is suited for use in industrial, construction, and manufacturing environments where PAPR systems are deployed for particulate respiratory protection. It is packaged individually, making it practical for on-demand replacement during routine maintenance of PAPR equipment. Typical applications include settings with elevated dust concentrations, abrasive blasting operations, or other particulate-generating processes where continuous-flow respiratory protection is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eParticulate protection designed for PAPR system prefilter stage\u003c\/li\u003e\n\u003cli\u003eExtends service life of downstream primary filter cartridges by capturing coarse particles first\u003c\/li\u003e\n\u003cli\u003eIndividual packaging supports single-unit replacement and inventory management\u003c\/li\u003e\n\u003cli\u003eCompact form factor fits PAPR system filter housing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style prefilter replacement for ALLEGRO PAPR respirator systems that accept the 9350-04 prefilter format.

Power down the PAPR blower unit before opening the filter housing and replacing the prefilter. Inspect the filter housing seal and gasket for wear during each prefilter change. Follow applicable OSHA respiratory protection standards and the site's written respiratory protection program when servicing PAPR equipment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProtection Type\u003c\/strong\u003e: Particulate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFilter Type\u003c\/strong\u003e: Pre-Filter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 21 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 13 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 17 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 19 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 46182007\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ALLEGRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9350-04\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLEGRO INDUSTRIES","offers":[{"title":"Default Title","offer_id":51541068251442,"sku":"9350-04","price":749.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dfed81fe37bcdf18ff3c044b802bd805.jpg?v=1785868090","url":"https:\/\/voomisupply.com\/products\/allegro-9350-04-papr-particulate-prefilter","provider":"Voomi Supply","version":"1.0","type":"link"}
