SR 76-2 S, S/M (Stationary Storage)

SR 76-2 M, S/M (Portable escape hood)

SR 76-2 S, M/L (Stationary Storage)

SR 76-2 M, M/L (Portable escape hood)

Face piece:
Available in Small/Medium and Medium/Large sizes and fits most adults and teenagers.
Hood:
The hood is based on a Sundstrom silicone half mask, which is mounted in a hood made of chemicals-resistant material.
Visor:
Scratch-resistant, anti-mist, polycarbonate
Fitting:
The hood can be put on quickly and simply, without prior adjustment.
Temperature:
-30°C to +70°C (-22F to +158F)
Filter:

The hood is equipped with combined filter SR 299-2, ABEK1-Hg-P3 and provides protection against all types of particles and following gas types:

A1 organic gases and vapours, such as solvents, with boiling points above 65oC.
B1 inorganic gases and vapours, such as chlorine, hydrogen sulphide and hydrogen cyanide.
E1 acidic gases and vapours such as sulphur dioxide and hydrogen fluoride.
K1 ammonia and certain amines, such as ethylene diamine.
Hg mercury vapour.
Weight:
490 g
Size of pack:
120 x 120 x 170 mm (4.7" x 4.7" x 6.7 ")
Storage:

The hoods are vacuum-packed in aluminium bags. The SR 76-2 M is delivered in a contingency bag made of nylon and designed for mounting on a belt.
