OTS Guardian Full-Face Mask
The Guardian incorporates a dedicated second-stage regulator into a full-face mask, allowing breathing through the nose or mouth. Its silicone skirt has a double sealing surface, and the equalising block can be adjusted to suit the wearer.
- Dedicated removable second stage for cleaning and storage; not usable independently of the mask.
- Adjustable equalising block.
- Airflow directed across the visor to help limit fogging.
- Port for compatible OTS communications equipment.
- Ambient Breathing Valve for surface use.
- Mask bag and low-pressure hose included.
Communications equipment is sold separately. Use requires appropriate full-face-mask training and a compatible breathing system. Follow the OTS manual for fitting, operating limits and maintenance.
