Alpha Sentinel Half Face Mask
A 140-gram reusable elastomeric half mask in three sizes, with click-fit filters and a low-profile shape that clears other PPE.
EN 140CAT III
Overview
At 140 grams the Sentinel sits light enough on the face that the harness does not have to be over-tightened to hold position — which is usually what makes half masks uncomfortable by mid-shift. The low profile is deliberate: it keeps the field of vision open and avoids fouling safety spectacles or a helmet. Filters click into place without threading.
Features
- Large exhalation valve reduces heat and moisture build-up
- Low profile maximises field of vision
- Click-fit filter connection
- Spare parts available for maintenance
