Military-Standard Protection Against CBRN Threats
The NBC-17 SOF 40mm threaded gas mask filter delivers certified defense against chemical, biological, radiological, and nuclear (CBRN) hazards. Engineered for NATO-standard respirators, this filter integrates with full-face masks, mouthpiece assemblies, and PAPR/TAPR systems (excluding MB-90 PAPR*) to safeguard against toxic agents in high-risk environments.
Critical Compatibility Note: Due to shortened threading, the NBC-17 SOF filter is NOT compatible with the MB-90 PAPR unit.
Key Features & Benefits
- 10-Year Factory-Sealed Shelf Life – Reduce long-term costs with a decade of reliable readiness when stored unopened (-5 °C to +30 °C).
- NATO-STANAG 4155 (EN 148-1) Compliance – Rd 40×1/7" threading ensures interoperability with 40 mm NATO respirators globally.
- Military & Specialist Trusted – Deployed by armed forces, CBRN response units, and special operations personnel worldwide.
- Robust Hard-Polymer Construction – Impact-resistant design withstands operational stress and physical damage.
- CE-Certified & EN 14387+A1 Compliant – Tested to European standards for maximum respiratory safety; CE mark (“CE” symbol) present.

Usage & Maintenance Guidelines
Lifetime Estimate: Usage duration depends on contaminant concentration; estimate by comparing workplace exposure levels to the minimum DAC values above.
Storage: Keep factory-sealed in original plastic. Ideal: −5 °C to +30 °C, RH <80%. Tolerates −30 °C to +50 °C, RH <95% (sealed). Do not regenerate; never clean with compressed air/water; do not use past expiration date.
Disposal: Treat as hazardous/special waste. Follow local regulations for the filtered substances. Remove from respirator and dispose of as solid special refuse.
