About this product
Engineered for professionals facing the world's most severe chemical, biological, radiological, and nuclear (CBRN) hazards, the MIRA Safety C21 Full Face Respirator represents the pinnacle of respiratory protection technology. Born from our Italian engineering excellence, this next-generation mask delivers superior safety, unmatched comfort, and tactical versatility for critical operations in extreme environments.
Unrivaled CBRN Protection & Safety Engineering
- Certified Excellence: CE certified to EN 136:1998 Class 3 for full-face respirators.
- Proven CBRN Defense: Advanced protection validated by Proqares Test Report no. 105474.
- Superior Seal & Fit: Achieves a fit factor >10,000 (EN 136 requirement: 2,000), ensuring maximum barrier integrity. Available in three precise sizes (Small, Medium, Large).
- Auto-Shut-Off Safety (Accessory): Optional auto shut-off valve system helps prevent contaminated air ingress during filter changes (accessory coming soon).
- Extreme Environment Ready: Operationally tested and reliable across –40°C to +70°C.
Engineered for Peak Performance & Endurance
- Reduced Breathing Fatigue: Advanced airflow minimizes resistance (Inhalation: 1.9 mbar @ 160 L/min; 0.7 mbar @ 95; 0.3 mbar @ 30). Exhalation: 1.7 mbar @ 160 L/min. The low-CO₂ inner mask limits CO₂ re-breathing to 0.6%, helping reduce fatigue and maintain alertness during extended wear.
- Crystal-Clear Vision: Robust panoramic visor (>91.7% natural FoV; 88.2% binocular — Apave Test Report no. 22.1386.001.1), treated for scratch and chemical-agent resistance. Ballistic protection (Newton Test Report no. 10413-05031039). Optical Class 1 clarity; close-set geometry supports visual aiming systems and accommodates corrective vision via the Spectacle Kit.
- Optimized Filter Integration: Universal 40 mm NATO / EN 148-1 threaded connection. Side-mounted filters (left or right configurable) avoid FoV obstruction; fully compatible with MIRA Safety filters (e.g., NBC-77 SOF®, VK-530, P-Can®).
Tactical Versatility & User-Centric Design
- Ambidextrous Filter System: Patented side-vent design allows quick switching between left or right mounting for optimal weapon handling and situational awareness. Available in left- or right-side configuration; orientation is also user-configurable.
- Enhanced Communication: Integrated speech diaphragm; optional microphone accessory available for amplified comms.
- High-Flow Hydration: Designed for integration with CamelBak® systems.
- Helmet Compatibility & Comfort: Compact profile integrates with tactical helmets and CBRN suits.
- Anti-Fog Technology: Directed airflow minimizes visor misting.
- 6-Point Head Harness Options: 3D fabric (standard) for fast donning; rubber harness available separately.
- Chemical Resistance: Bromobutyl rubber facepiece and treated surfaces facilitate easy decontamination after exposure.
