Constructed from high-impact, chemically resistant molded polymer, these retainers allow industrial and aerospace MRO operators to add N95, R95, or P100 pre-filters directly over gas\/vapor cartridges (such as organic vapor or acid gas elements). By stacking a particulate pre-filter on top of a chemical cartridge, North pre-filter retainers establish a dual-protection combination barrier that traps airborne overspray, dust, and mist before they clog the main chemical absorbent layer, significantly extending cartridge service life.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eTechnical Specifications \u0026amp; Cross-References\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Honeywell Safety Products \/ North®\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e North® N-Series Pre-Filter Retainer Covers\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number \/ SKU:\u003c\/strong\u003e N750036 (Package of 2 retainers \/ 1 pair)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Construction:\u003c\/strong\u003e High-Impact Molded Polypropylene \/ Polymer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Translucent \/ Clear Polypropylene\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCartridge Compatibility:\u003c\/strong\u003e Designed specifically for all Honeywell North® N-Series Gas and Vapor Cartridges (e.g., N75001L, N75002L, N75003L)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePre-Filter Compatibility:\u003c\/strong\u003e Holds Honeywell North® N-Series Prefilter Discs (e.g., N750029 N95 pre-filters, N750030 R95 pre-filters)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAttachment Mechanism:\u003c\/strong\u003e Tool-less snap-fit ring enclosure over cartridge rims\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApproved Specifications \u0026amp; Regulatory Conformance:\u003c\/h3\u003e\n\u003cp\u003eHoneywell North pre-filter retainers comply with strict NIOSH respiratory accessory protocols:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNIOSH System Certification:\u003c\/strong\u003e Maintains full NIOSH 42 CFR 84 system approval when used in combination with certified Honeywell North cartridges, pre-filters, and half or full facepieces (\u003cstrong\u003e5500, 7700, 5400, 7600, RU6500 series\u003c\/strong\u003e).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOSHA Respiratory Standards:\u003c\/strong\u003e Meets OSHA 1910.134 guidelines for particulate pre-filtration accessory components.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch3\u003eKey Features \u0026amp; Performance Benefits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtends Chemical Cartridge Lifespan:\u003c\/strong\u003e Shields primary carbon absorption beds from liquid overspray and solid particulates, preventing premature clogging and lowering operating costs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool-Less Snap-On Assembly:\u003c\/strong\u003e Snaps securely over N-Series chemical cartridges without tools, ensuring rapid field replacement of saturated pre-filters.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable \u0026amp; Chemically Resistant Polymer:\u003c\/strong\u003e Built to withstand harsh shop environments, solvent wipes, spray paint overspray, and high humidity without warping or cracking.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecure Seal Geometry:\u003c\/strong\u003e Features a continuous perimeter lip that clamps the pre-filter flat against the cartridge intake, preventing particulate bypass around the edges.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch3\u003eTypical Applications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAerospace \u0026amp; Automotive Spray Painting:\u003c\/strong\u003e Used to secure N95\/R95 pre-filters over organic vapor cartridges to capture liquid paint mist, primers, and clearcoats.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChemical Processing \u0026amp; Solvent Washing:\u003c\/strong\u003e Holds pre-filters to stop airborne dust and aerosol droplets from entering chemical vapor cartridges during tank washing and degreasing.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComposite Fabrication \u0026amp; Sanding:\u003c\/strong\u003e Enables combination protection against hazardous resin vapors and airborne fiberglass or carbon dust during MRO composite repair operations.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PIP","offers":[{"title":"Default Title","offer_id":56191926468980,"sku":"N750036","price":4.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0888\/2991\/9604\/files\/PIP-North-N750036.png?v=1790630183","url":"https:\/\/145.aero\/products\/north%c2%ae-pre-filter-retainers-2-pairs","provider":"Aircraft Shop Supply","version":"1.0","type":"link"}
