[simpits-tech] Breathing Air was Re: Cockpit builders quote....

[David C. Allen]

Hello to the Gang

The problem with filters, is when do you change them??????

I purchased a new 2216 PSI Scott Air-PAK Aluminum bottle from Ebay. 
The seller a Fire department that was converting to a higher pressure 
and this bottle had not been in service. (Watch out for bottles that 
have a fixed (in years) service life) The bottle I purchased has a 
current hydrostatic test date.

Our local volunteer Fire Department offered to send my bottle in when 
it needs it's next pressure test.

I also purchased a 2 stage regulator, and a 2500 PSI pressure 
transducer with a 0 to 5 VDC output.
The transducer dc output will drive the 737's Crew Oxy pressure 
Indicator. This will allow the bottle pressure to be monitored on the 
aft overhead panel just like the real aircraft

The local medical supply has breathing air hose, and I will plumb the 
two Quick dawn masks so the head band will inflate and breathing air 
will be available to the mask.

The bottle can be filled at a medical or industrial gas supply 
company. The local industrial gas supply company only sells "Medical" 
grade of breathing air.

I don't have a price on the cost of filling, because I just have a 
box of parts LOL
