Gas Mask Filter A2B2E2K2-P3

28,95 €

The A2B2E2K2-P3 is a combined multi-threat respirator filter designed for full-face and half-mask systems with a standard 40 mm NATO / EN 148-1 threaded connection. It provides broad-spectrum protection against industrial chemical vapours, toxic gases, and particulates, and is commonly used in professional civil defence and industrial safety applications.

The classification follows the EN 14387 filter standard, where each letter corresponds to a specific hazard class and the P3 rating defines the highest level of particle filtration.

Key protection coverage:

A2: Organic gases and vapours (boiling point >65°C)
B2: Inorganic gases and vapours
E2: Acid gases (e.g. SO₂, HCl)
K2: Ammonia and ammonia derivatives
P3: High-efficiency particle filtration (≥99.95%), including fine dust, aerosols, and bioaerosols

In practical terms, this type of filter is used for CBRN-level industrial environments, emergency response, and high-exposure chemical handling scenarios where multiple hazard types may be present simultaneously. It does not cover every possible gas (e.g., CO or NOx require specialized filters), so its protection profile is broad but not universal.

Standard: EN 14387 / EN 148-1
Thread: 40 mm NATO
Type: Combined gas + particle filter
Use case: Industrial safety, civil protection, chemical exposure environments
Particle efficiency: P3 (highest class)

This is a multi-chemical combination filter, not a single-purpose cartridge, and performance depends heavily on correct mask seal and adherence to service life limits.
