Powered Air Respirator 3M S-433L, white, approved to EN 12941 and EN 166

The 3M S-433L powered air respirator in white is a combined respiratory and eye protection solution designed for professionals working in environments with airborne contaminants and splash or impact hazards. Approved to EN 12941 for powered filtering devices and to EN 166 for eye protection, this unit supplies a continuous flow of filtered air to the facepiece, reducing breathing effort and helping to maintain a secure seal while providing integrated visor protection. The system is intended for users who require both particulate filtration and splash/eye coverage in industrial, maintenance, and cleaning operations.

Advantages

The powered airflow reduces inhalation resistance compared with non-powered respirators, improving comfort during prolonged wear and lowering fatigue for the user. The integrated visor offers clear, wide-field eye protection that meets EN 166 impact and optical requirements. Lightweight construction and balanced airflow distribution help maintain a stable seal and reduce facial pressure points. The white finish supports visual identification of cleanliness and is suitable for environments where a neutral appearance is preferred.

Suitable for

• Industrial maintenance and repair tasks with dust, fumes or light aerosols
• Cleaning and sanitation work involving sprays and splashes
• Manufacturing processes with particulate or low-to-moderate airborne contaminants
• Work requiring combined respiratory and eye protection for extended periods

How to use

Before each use, inspect the unit for visible damage and ensure filters and battery (or power source) are properly fitted and charged according to manufacturer instructions. Don the device ensuring the visor and face seal sit correctly and that airflow is maintained when the unit is operating. Adjust headgear or harness for a secure, comfortable fit without compromising the seal. Replace filters or consumables as indicated by performance guidelines or when breathing resistance increases. Store the respirator in a clean, dry place away from direct sunlight and contaminants when not in use.

Usage recommendations

Use the powered air respirator in accordance with workplace risk assessments and applicable safety procedures. Select appropriate filter types for the specific contaminants present and follow local regulations for respiratory protective equipment. Ensure users receive instruction on correct fitting, operation, and maintenance, and perform regular checks to verify the unit continues to meet performance requirements.
