Features
1. Wide-Vision Panoramic Visor: Utilizes a novel spherical 3D window design, achieving a total field of vision of over 81%. Excellent optical performance and high light transmission ensure users maintain a broad and clear view in complex environments.
2. Ergonomic Fit Design: The orinasal mask is precisely designed based on human facial contours, available in S/M/L sizes to ensure a perfect fit for various face shapes. Inhalation and exhalation channels are separated, preventing exhaled air from mixing with fresh air inside the mask and minimizing CO₂ rebreathing risks.
3. Dual Anti-Fog Technology: The inner surface of the visor features a professional anti-fog coating. Additionally, dry compressed air from the cylinder continuously flows across the inner visor surface, effectively preventing fogging during prolonged operations and ensuring clear vision.
4. High Durability Visor: The outer surface of the visor is hardened, providing excellent abrasion and scratch resistance. It effectively resists interference from on-site debris, dust, and other particles.
5. Premium Silicone Face Seal: The face seal is made of flame-retardant silicone rubber, offering excellent adhesion to facial skin. It remains soft and elastic even at extreme low temperatures down to -40°C, without stiffening or hardening. The material is non-allergenic, ensuring comfortable and safe wear.
6. Nomex/KEVLAR Flame-Retardant Head Harness: Features a 5-point adjustable fastening system. The harness is primarily constructed from inherently flame-retardant and cut-resistant Nomex®/KEVLAR® fibers and includes a supportive neck strap. It allows for quick and easy donning, ensures excellent airtightness, and can be freely adjusted to fit any head shape.
7. Positive Pressure Operating Principle: The mask interior consistently maintains a slight positive pressure relative to the external environment, effectively preventing the ingress of toxic gases, smoke, and other contaminants through any gaps, ensuring breathing safety.
Product Highlights
Clear Communication: Equipped with a high-strength sound-transmitting diaphragm for effective voice transmission, facilitating on-site communication and coordination.
Rapid Connection: Features a standard quick-plug interface for fast and secure connection to the demand valve.
Comfort and Stability: Scientific weight distribution and a soft face seal design ensure comfort during prolonged wear without fatigue.
Multi-Scenario Adaptability: Verified through multiple performance tests including anti-fog, scratch resistance, low-temperature resistance, and flame retardancy.
