Compressed air attachment for half- and full face masks.
The SR 307 compressed air attachment is designed for connection to Sundström half masks and full face masks.This combination forms a breathing apparatus designed for continuous air flow, for connection to a compressedair supply. The SR 307 is an accessor y that enables a given facepiece to be used as either a filtering deviceor a protective device supplied with compressed air. The compressed air attachment is especially intendedfor applications involving heavy and sustained work in environments in which the pollutants have poor warningproperties or are particularly toxic.The SR 307 is made of a material which is not liable to give rise to frictional sparking, which enables the attachmentto be used in an explosive or flammable environment. The flow meter and warning whistle for temporary andcontinuous monitoring of the air flow rate are included. Control valve mounted on the user’s belt is included.
