- A specialized, consumable filtration component engineered exclusively for the 3M Versaflo TR-300 and TR-300+ Series Powered Air Purifying Respirator (PAPR) platforms, it strains out dangerous inhalable particles to provide a constant supply of safe air
Uses
- Dust & Fiber Environments:
- Deployed across woodworking, textile milling, masonry, and construction applications involving heavy sawdust, silica dust, or drywall insulation particles
- Pharmaceutical & Lab Operations:
- Extensively used when compounding raw ingredients, handling toxic fine chemical powders, or conducting life science research
- Healthcare Isolation & Aerosols:
- Utilized in clinics and hospitals to shield frontline staff from biological aerosols, viruses, and airborne patient pathogens
- Grinding & Metalworking Dusts:
- Protects technicians against fine metallic dust, fly ash, and particulate debris generated during finishing operations
- Target Hazard Limitations:
- Explicitly approved by NIOSH for High-Efficiency (HE/P100 class) particulate filtration against solid and liquid aerosols, it provides zero protection against gases, chemical vapors, or organic solvents
Features
- 99.97% HEPA Efficiency:
- Employs advanced, high-density microfiber filtration media capable of capturing at least 99.97% of airborne particles down to 0.3 microns
- Snap-In Gasket Connection:
- Features an intuitive, tool-free design that utilizes a built-in locking gasket to snap flush against the TR-302N blower motor housing
- Filter Cover Compatibility:
- Integrates natively underneath the standard [TR-370 or TR-371 filter covers] (1.1.3, 1.2.5), these covers can house an optional prefilter to catch large-scale debris
- Individually Sealed Packaging:
- Each filter in the 40-pack arrives hermetically sealed in its own clean wrap, which prevents contamination during transit and ensures stock rotation traceability in regulated settings
- Legacy System Drop-In:
- Functions as the official, direct factory replacement for the older, discontinued TR-3710N filter model
Benefits
- Substantial Fleet Cost Savings:
- Bundling five filters to a single part number lowers the per-unit acquisition cost for safety managers keeping multi-worker shifts stocked
- Lightweight & Well-Balanced:
- Keeps the overall profile of the belt-mounted TR-300 unit slim and compact, this minimizes worker lower-back stress during long, physically demanding shifts
- Eliminates Lung Fatigue:
- Because the battery-operated motor pulls ambient air through the dense HEPA web, the user experiences zero breathing resistance which dramatically improves workplace compliance compared to passive masks
- No Annual Fit Testing Required:
- When paired with a loose-fitting Versaflo hood or headtop, positive-pressure air delivery eliminates the need for tight skin seals to avoid the logistical headache of yearly OSHA face-fit testing
- Automatic System Syncing:
- Built to work with the TR-300+ blower’s safety computer. If the filter becomes completely loaded or clogged with dust, the system actively triggers an audible and visual alarm to prevent airflow dropping
