- As a first line of defense for 3M TR-600 and TR-800 Series Powered Air Purifying Respirators (PAPRs) since it captures large airborne particles and debris before they reach the main HEPA filter or gas/vapor cartridge, preventing premature clogging and ensuring consistent airflow
Uses
- High-Particulate Environments:
- Ideal for heavy-dust industries like grinding, sanding, stone masonry, tile fabrication, and composite finishing
- Filter Protection:
- Used alongside the 3M Versaflo Spark Arrestor (TR-662) for added physical protection in sparks and heavy-debris applications like welding and paint preparation
- Versatile Compatibility:
- Can be installed directly in frontof either particulate (HE) filters or combination gas/vapor cartridges
Features
- Extended Filter Life:
- Traps coarse dust and debris, preventing the main filter media from filling up too quickly
- Maintenance-Free:
- The disposable design requires no cleaning. Simply discard and replace the prefilter when it becomes clogged or damaged
- Lightweight:
- Adds minimal weight (approx. 0.06 lbs) to the PAPR system
Benefits
- Reduced Operating Costs:
- By protecting expensive primary HE filters and cartridges, you replace main filters less frequently, driving substantial cost-per-worker savings
- Optimized System Performance:
- Minimizing filter loading maintains a steady airflow at the blower's powered rate and prolongs battery life between charges
- Simplified Maintenance:
- Keeps the primary filter media cleaner for easier storage and system maintenance
