SKYTEC Alpha Sentinel Half-Face Respirator Mask

Reusable | EN140 Certified | Low Breathing Resistance | PPE-Compatible Fit

This high-performance reusable half-mask respirator is engineered for professionals in demanding environments. Lightweight at just 140g, it delivers long-term comfort, protection, and a close facial seal across a wide range of applications, including dust, fumes, vapours, aerosols, and mold spores.

Available in three sizes (S, M, L), this low-profile half-face mask features a fully adjustable 4-point head harness and a premium elastic strap for a secure, custom fit. The thermoplastic elastomer construction offers flexibility and durability for extended daily use.

Designed for visibility and compatibility, it sits neatly beneath safety visors, face shields, welding helmets, and other PPE. It connects seamlessly to Alpha Sentinel filters via a quick-click mechanism, allowing for fast filter changes even in high-risk environments.

The large exhalation valve significantly reduces heat and moisture buildup inside the mask, delivering low breathing resistance — ideal for physical tasks in warm or confined conditions.

Tested to EN140:1998 and both CE and UKCA certified, this P3-compatible half-mask respirator is suitable for industries where workplace exposure limits (WEL) demand reliable respiratory protection. Compatible with P3 R D filters for reliable protection against fine dusts, mists, and aerosols.
