The Sundstrom SR307 Compressed Air Attachment is a small and unintrusive

The SR307 compressed air attachment is designed for connection to Sundström Air Purifying Respirator (APR) half masks and full face masks.

This combination is a Supplied Air Respirator (SAR) in Continuous Flow mode (CF), for connection to a compressed air supply.

The SR 307 is an accessory that enables a given facepiece to be used as either a Air Purifying Respirator or a Supplied Air Respirator (SAR).

The compressed air attachment is especially intended for applications involving heavy and sustained work in environments in which the pollutants have poor warning properties 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 attachment to be used in an explosive or flammable environment.

The flow meter and warning whistle for temporary and continuous monitoring of the air flow rate are included. Control valve mounted on the user’s belt is included.

Many Sundström half masks and full face masks can be fitted with compressed air attachments, rendering them positive pressure respirators
Using the adapter attachment means that no permanent modifications are necessary — the attachment fits like a filter
The SR307 can be used with the SR63 supplied-air hood
