3M Replacement Cassette R3-KAS.U-M — filtration cassette for compatible 3M respirator systems

3M Replacement Cassette R3-KAS.U-M is a modular filtration cassette intended for use with compatible 3M respirator systems. The cassette is designed to be fitted to approved 3M mask bodies to provide a removable filter element that helps protect against airborne particulates and certain gases when used as part of an appropriate respiratory protection assembly. It is intended for occupational and industrial environments where ease of maintenance and straightforward replacement of the filter element are required.

Advantages

The cassette offers a compact, replaceable filtration module that simplifies filter changes and routine maintenance of compatible respirator systems. Its modular design enables quick attachment and detachment without modifying the mask body, supporting continued use of the same respirator platform. The component is engineered to meet performance expectations for workplace respiratory protection when combined with appropriate mask bodies, seals and user practices.

Suitable for

• Industrial workplaces with airborne particulates
• Environments where detachable filter elements simplify maintenance
• Application with compatible 3M mask bodies for occupational respiratory protection

Key specifications

• Modular cassette design for detachable filtration element
• Compatibility with specified 3M respirator systems (use only with approved mask bodies)
• Intended for protection against particulates and selectable gas/vapour types when used with appropriate filter media
• Designed for occupational and industrial use and routine filter replacement

How to use

Fit the cassette to a compatible and approved 3M mask body following the mask manufacturer’s instructions. Ensure the cassette is fully engaged and locked into position, and perform a user seal check as required by the respirator guidance. Replace the cassette when breathing resistance increases noticeably, when damage or contamination is observed, or according to workplace safety procedures and exposure assessments. Store unused cassettes in a clean, dry environment away from contaminants and extreme temperatures.

Usage recommendations

Use the cassette only with compatible 3M mask bodies and within the conditions of use defined by workplace risk assessments and the respirator system documentation. Select the appropriate cassette/filter type for the specific particulate and gas exposures present, and follow established maintenance, fit testing and replacement intervals to ensure effective respiratory protection.
