When people start sourcing and filling their own filters with materials sourced from non compliant suppliers
And then putting them in my machines - it is my Brand that people look at with expectations of air quality
Below is a example of things that can go horribly wrong when people do what they want and don't source the correct materials
I was on holiday at this site - running 3 Bauers and a Nitrox Membrane system - i felt the air was not up to standard and asked to see their filters and compressors
Attached you will see a picture of molecular sieve and activated carbon which i pulled out of a machine ( a Bauer with P21 filters - woefully inadequate for the conditions ) which they were repacking - just in layers !! not with the carbon running up the middle and molecular sieve on the outside
They were re - using the sponge pads - not even washing them or putting new ones
The oil !! we drained it and it was completely black ( this was sourced from a Bauer agent - who was decanting Shell oil into a 5 L and writing by hand "Bauer synthetic oil " it may have been breathing air grade oil - Nitrox compatible ?? Clearly not as it was black
I had the most disgusting air ever from this Bauer setup
Its seems you have nothing good to say about Coltri - other than its a Paintball machine pressed into service
( yes we do supply paintball - but the majority of our units end up in the Scuba and Fire markets )
So instead of knocking Coltri - why not put your clearly vast knowledge to educating people out there of correct practices and not encouraging that
they start repacking their filters with dubious materials
At least I know when i send out a machine it has a adequate filtration system specced as standard
And we supply original oil - it is specced for our machines for Nitrox
And when my clients re pack their filters they are using the correct materials sourced from me -
So i ask you ! would you like to breathe off a machine with correct materials and a properly trained operator or someone who is putting in the cheapest materials he can find
My goal is the best quality air out there for all clients - through education and not scaremongering
and i try and keep my materials at the best possible pricing
see the pic of materials from the mentioned site
what should be molecular sieve has been identified as Activated Alumina
and heaven knows what that carbon is ?
and you can make your own deductions as to which is the proper oil
