Sundström SR 294 Gas Filter A2B2E1

The SR 294 A2B2E1 gas filter offers enhanced protection against organic, inorganic and acidic gases and vapours, and is designed for professional applications requiring a higher level of protection. Thanks to its Filter Class 2 rating, it has a higher adsorption capacity than standard filters and is ideal for demanding working environments.

System & Application

The filter complies with combination class A2B2E1 and provides simultaneous protection against multiple types of gas. Type A protects against organic gases and vapours (e.g. solvents), Type B against inorganic gases such as chlorine or hydrogen sulphide and Type E against acidic gases such as sulphur dioxide or hydrogen fluoride.

Thanks to filter class 2, the SR 294 offers a higher absorption capacity and longer service life than class 1 filters, making it ideal for longer periods of use or higher concentrations of pollutants.

The SR 294 is compatible with Sundström half masks (SR 100, SR 900) and full-face masks (SR 200). It can also be combined with the SR 510 P3 R particle filter to ensure protection against aerosols and particles.
