Kevin Gurr - Cis-Lunar wrote; an approximate L300 service price [snip] (if limited use logged) of possibly upto two years. The full service requirements for any Closed Circuit Rebreather will be very similar as common components will need to be replaced. The final price is yet to be defined, but will basically consist of O rings, regulator servicing, disenfecting, a calibration check, sensor replacement and batteries. Any damaged parts will also be replaced. end quote I work in a place that services rebreathers. How do you do that for 300 pounds?? "O rings" Yep I'd say more than fifty O2 compatable, Plus mushroom valves, circlips etc Don't forget the O ring lands. Add cleaning, examining, O2 cleaning an lubing with O2 compatable grease. "regulator servicing" An open circuit reg, plus an integrated CC2 mouth grip (these are heaps more complex than you might expect) plus the Oxygen injector and dilutent injector. Heaps of O rings in each, both have to be striped and checked, then O2 cleaned and placed back in the units. "disinfecting" Yes, washing, drying, checking, we are talking *hours*. "a calibration check" How much is the test gear for this check worth? You have a very small number of sets out there to spread the cost of test gear amoungst. It isn't just a couple of checks like OC gear. This would take *hours* of highly skilled labour. There is the depth sensor, the on and off board gas pressures the activation of the gas injectors and I'm sure lots more. "sensor replacement" You quote 40 pounds for each sensor, are they compatable with MSA O2 analysers? I'd love to find a replacement at only a third of the normal cost. "batteries" Lithium? "any damaged parts will be replaced" A normal breathing hose is worth over 50 pounds just for one! The Cis-Luna hoses are meant to be really wizz bang, so they are not of the shelf items. A mould for a part like that costs *many thousands* how many units will be sold to amortise the cost of the tooling up? That is just *one* part of hundreds. I *can't* see how you could do this job in under 30 hours and I would expect it to take *much* longer. The 300 pounds is less 120 for the sensors (your figures) leaving 180 pounds. Less 20 pounds for the 50+ O2 O rings and mushroom valves. Less 10 pounds for the battery. Less 10 pounds for consumables (Krytox, cleaning agents, wipes, O2 and N2 for the test panel) I'm sure that there are lots of other expenses, I haven't mentioned sevicing the ofboard gas switch block and hoses but let's stop there. We now have 140 pounds to pay at least 30 hours labour. Possibly much more. Where do you get someone of the standard needed to work on this kind of gear for under 5 pounds an hour? Cheers Jason :)
