I filled my SCBA bottles again today and while topping off a warm tank that had cooled, I lost high pressure and I could not get more than 2k. The meter is right at 136.3 hours, or about 500 top-offs. That seems a little high, I bet I had about 300 top-offs so I wonder if the gauge is a little fast? I have a complete rebuild kit in-house so it looks like there will be no target shooting tonight, looks like BEER-30.
I pulled the head off and looked at everything, there was a slow water leak into the seal so I changed the oring and seal, the 2nd stage piston looked really good to me...? I put it back together and ran it again, still stops at 2k.Turned the compressor off (I usually do this after bleeding off the pressure in the line) and I heard a leak!The whole thing turned out to be an oring in the filter that had compressed enough to let a small cut start a leak and blew out at 2k every time I ran the compressor. 136.5 hours and still kickin!!!
