Self-contained breathing apparatus (fire SCBA) - PROPAK SCOTT Safety

The Propak self-contained breathing apparatus

Approved according to EN 137:2002 Type 2 – which includes the highly demanding flame resistance test – the Propak self-contained breathing apparatus offers an unrivalled performance level required by professional firefighters. Ultra-lightweight, this fireproof self-contained breathing apparatus is also MED 10^th amendment approved which means that it is approved to the latest marine certification.

Propak is a type 2 open-circuit self-contained breathing apparatus (OC-SCBA) with compressed oxygen. It is composed by a backplate, a padded harness and a powerful pneumatic system that includes a cylinder connector, a pressure reducer, a manometer, a low pressure whistle and a demand valve.

Combined, the reducer and the cylinder connector only feature two mobile parts in order to ensure maximum efficiency and reliability. The reducer can handle pressures up to 379 bar without prior adjustment. It features a bronze filter that protects the high pressure reducer against residues that may lay in cylinders.
