Half mask
Revision: 03

General information
Use of a respirator must be part of a respiratory protection program.
Three sizes S/M, M/L and L/XL.
The half masks are used either as filtering devices in combination with filters from the Sundström range, or in
combination with the SR 307 compressed air attachment which then serves as a breathing apparatus with
continuous flow for connection to a compressed air supply. A wide range of accessories are available.
When selecting equipment for SR 100 some of the factors that should be taken into account are as follows:
•Type of pollutant
•Concentrations
•Work intensity
•Protection requirements in addition to respiratory protective advice.
Risk analysis should be carried by a person who has suitable training and experience in the area.
