Climax Combined Filter A1P2 NR – Model 755 (Pair)

The Climax 755 A1P2 NR Combined Filter is a dual-protection gas and particulate filter from Spain's Productos Climax, designed for use with Climax half-face respirator masks. It provides Class A1 protection against organic vapours combined with P2 NR particulate filtration — making it a versatile single filter for environments with mixed gas, vapour, and aerosol hazards. The P2 particulate layer is independently replaceable, extending the service life of the gas filter body.

Key Features

• Combined A1 + P2 NR protection — single filter provides both organic vapour/gas and particulate protection simultaneously
• Replaceable P2 NR particulate layer — the P2 non-woven filter element is positioned on top of the gas filter cap and secured with a retainer ring; can be replaced independently when exhausted without discarding the gas filter body
• Multi-layer P2 non-woven filter media — engineered for maximum filtration efficiency against both solid and liquid aerosols
• Non-standard screw thread — compatible exclusively with Climax masks models 755, 756, and 810
• Lightweight ABS plastic body — durable and low-profile for minimal weight on the facepiece
• Sold as a pair (2 filters per pack)

What It Protects Against

• A1 — Organic vapours and gases with boiling point above 65°C (e.g. solvents, hydrocarbons, paint thinners)
• P2 NR — Solid and liquid aerosols — dusts, mists, fumes, and non-volatile particles
• Paint spray mist and solvent vapours
• Pesticide and herbicide aerosols with organic vapour content
• Industrial dusts and grinding/welding fumes (light exposure)

Protection Standard

Certified to EN 14387:2004 + A1:2008 — Combined gas and particulate filter, Class A1P2 NR. CE certified (0161). Colour code: Brown (A1) + White (P2) per EN classification. NR = Non-Reusable particulate layer — discard P2 element when breathing resistance increases or at end of shift.

• Store in sealed bag away from direct sunlight, heat, and humidity when not in use
• Always check expiry date printed on packaging before use
