What’s new with the Prism 2 CE version?

So, what’s new with the Prism 2 CE version? The answer is…not a lot! After all, if it ain’t broke, don’t fix it.

Since 2009 we have been building the Prism 2 rebreather in its current configuration with minimal mechanical changes. All of which have been released to our customer base individually or as running changes to our product.

Qinetiq Lab – Breathing machine and P2 FMCL ready for test

In early 2019 we submitted both the Prism 2 front mounted counterlung and back mounted counterlung for a true 3rd party performance test at Qinetiq labs in the UK. The results not only showed both variants exceeded EN 14143:2013 standards, but proved the Prism 2 is one of the best performing rebreathers on the market with one of the lowest work of breathing numbers and an incredibly efficient scrubber design.

Starting October 2019, all new Prism 2’s shipped have been the CE compliant model. Pricing and part numbers remained unchanged. Our new user manual in the Hollis Rebreathers library includes the operation of the new CE model, found here: https://www.hollisrebreathers.com/support/manuals/

So what changed as a result of CE?
