3M Scott ProPak Sigma SCBA
The ProPak Sigma SCBA from 3M - Scott Safety is a Type 2 open-circuit self-contained breathing apparatus set.
Please note: cylinders must be purchased separately.
This SCBA set has been designed as a cost-effective solution for marine and industrial firefighting environments. It has minimal padding with rigid back frame construction.
Those with facemasks within this bundle come with a Vision 3 Facemask. They can also be configured with a ProMask Positive Pressure facemask; please speak to our sales team in the live chat if you require this facemask. The 3M Scott ProPak Sigma should also be used with a range of composite or steel cylinders.
With a tempest demand valve, this provides low breathing resistance with first-breath automatic activation.
