Filter cartridge Climax 757-N A1B1E1K1 for half masks 757-S, 742 — 1 piece

Climax 757-N A1B1E1K1 is a single replacement filter cartridge compatible with Climax half masks 757-S and 742. The cartridge combines adsorption and chemical filtration media to reduce exposure to a range of airborne contaminants: organic vapours, inorganic gases, acidic gases and ammonia/amines. Supplied as one piece, the 757-N cartridge is intended for use where gaseous and vaporous contaminants are present and particulate filtration is not the primary function.

Advantages

The Climax 757-N cartridge offers multi-class gas and vapour protection in a compact, single-cartridge format that is easy to install on supported half masks. Its combined filter media eliminates the need to change cartridges when users face mixed atmospheres containing organic solvents, inorganic gases and acidic or alkaline contaminants. The cartridge is lightweight and designed for straightforward replacement, supporting routine maintenance and minimizing downtime.

Suitable for

• Industrial environments with organic solvent vapours (paint shops, degreasing)
• Maintenance and repair tasks involving inorganic gases and fumes
• Laboratory work handling acidic gases or ammonia/amines
• Short-duration operations where gas and vapour protection is required alongside a compatible half mask

Key specifications

• Protection classes: A1 (organic vapours), B1 (inorganic gases), E1 (acidic gases), K1 (ammonia/amines)
• Form factor: single replacement cartridge for half masks
• Compatibility: designed for use with Climax half masks 757-S and 742
• Supply quantity: one cartridge per package

How to use

Before use, inspect the cartridge for damage and ensure the packaging seal is intact. Attach the cartridge to a compatible Climax half mask (models 757-S or 742) according to the mask manufacturer’s fitting instructions, ensuring a secure and airtight connection. Perform a user seal check on the assembled respirator to confirm correct fit. Replace the cartridge when breathing resistance increases noticeably, if an odour breakthrough is detected, or according to your organisation’s respiratory protection program and local regulations.

Usage recommendations

Use the Climax 757-N cartridge only with compatible half masks and within the limitations of its protection classes. It does not provide particulate filtration unless combined with an appropriate particulate pre-filter; therefore, assess both gas/vapour and particulate hazards before selecting respiratory protection. Store cartridges in a dry, cool place in their original packaging and replace after the recommended service life or upon contamination.
