Three parts. Three different roles.
Usage & Safety
When should I replace each part?
When should I replace each part?
Use a cartridge change schedule based on the identified contaminant, exposure conditions and manufacturer instructions. Do not rely on smell alone. Replace damaged cartridges and do not wash filtration media.
Replace pads when dirty, damaged, wet or when breathing resistance increases. Follow the supplied instructions. Do not wash filter media. A pack quantity is not a guaranteed number of days or weeks of protection.
Replace A8502 covers if cracked, loose or damaged.
Which components fit together?
Which components fit together?
A8510/A8530/A8560 cartridges use compatible A8501 pads and A8502 retainers on listed AMS A620, A680 and A820 systems. A420P uses a separate A4520/A4521/A401 system. These parts do not replace 40mm threaded filters.
What are the safety limits?
What are the safety limits?
Choose filtration for the identified contaminant and concentration. A8501 pads alone do not protect against gases/vapors; A8502 covers do not filter air. Air-purifying respirators do not supply oxygen. Do not use in oxygen-deficient, unknown or immediately dangerous atmospheres, or for carbon monoxide. Follow the product instructions.
