The BLS 425 ABEK2P3 R filter offers protection against: 

• Particulates or dusts, mists and fumes
• Organic and inorganic gases and vapors with a boiling point above 65 °
• Acid gases including hydrochloric acid, sulfuric acid, hydrofluoric acid etc.
• Ammonia and derivatives

Its structure consists of a durable ABS casing with two filters inside combined to offer double protection: a pleated fabric filter allows you to filter 99.99% of particulates, equally reducing respiratory fatigue; a particularly porous activated carbon filter traps gases and vapors on the internal surfaces fully respecting all safety standards thanks to the absence of toxic additives.

The BLS 425 ABEK2P3 R filter is compatible with the 5000 series (5150, 5400) and 3000 series full face masks, thanks to the universal connection with standardized thread.

The device is certified as Category III PPE in compliance with the technical standards EN 143: 2000 + A1: 2006 and EN 14387: 2004 + A1: 2008.
