Filling the scba

[Alderman]

I was able to get a 30 minute SCBA bottle with a year and 1/2 service life left on it for $70. Was curious to see how long it would take to fill to 200 bar with the Yong Heng. I just got my compressor a little while back and changed the oil after 15 minutes of run time. I was able to get to 200 bar in about 20 minutes which I did in three sessions. I could have run longer but I was holding the temperature to around 55c. I’m sure a bigger water bucket would give me some more run time at a lower temp. 
At this point all of my guns are 200 bar so I want to keep the pressure near that until I get the hang of filling from a bottle. 
With these low pressures the compressor never gave any indication of struggling.

Even at 300 bar it doesnt really struggle just takes longer. I'd get royal purple oil and a good setup for moisture/oil control.

Great compressors.

I have Royal Purple in it and am currently running two filters.

FWIW, my YH is not reliable for stopping at the set pressure or for reading the right pressure. I have to keep a close watch on the bottle or the gun while pumping.

I run my yh with the bucket in the bathtub and the return line in the tub as well and I just trickle the cold water into the bucket so it is always getting fresh cold water I can fill my 60 min scba tank from 2000 to 4300 in 23 min and never have to stop for temp I never let it go above 55 usually it never gets close but fresh cold water all the time is key
