Bauer Oceania maximum pressure 3200?

[terrykuz]

I bought a used gasoline powered Oceania. It pumps to 3200 PSI then some type of regulator begins to bleed off the pressure. 

So I guess it was set up for scuba tanks. I have a SCBA so I want 4500 or so. So how can I raise the pressure? I assume that the Oceania can handle 4500, and the only difference is this pressure relief valve?

Thanks, Ter

I don’t have a Bauer, but have been told by at least three people that have them that they are all designed for 310 bar. The only difference is the 3rd stage relief setpoint. You can adjust that yourself.

Yup my bauer also came set to 232bar initially.

Had the bauer tech at the dive shop raise the pressure point of the relief valve - took about a minute. 

One thing to note - the pressure gauge unit is different for 232 and 310 bar - both are safe to and read to that level, but the 232bar gauge is supposed to be quite inaccurate beyond about 280bar and they recommend you switch it out

Most dive tanks fill to 232 bar pressure so most Bauers are factory set for that pressure. I think you have a Bauer Oceanus which has a P21 triplex filter housing. It isn't a complex procedure to increase the pop-off valve's release pressure. The top of the housing has a wire which is clamped onto two of the four threaded allen head bolts that hold the cap in place . That wire is to keep the pressure adjustment from being adjusted. If you do an online search for Bauer compressor pressure adjustment you will see that after that wire is removed the 4 bolts holding the cap can be removed to reach the setting adjustment. A flat head screwdriver and open ended 13mm wrench are needed to adjust the pressure. Once the cap is removed, the lock nut is loosened and the screw is turned counter-clockwise to build more pressure before the pop-off valve opens. It isn't difficult to adjust but you should make the increases in small increments until the desired pressure is reached.

If you do an online search for Bauer compressor pressure adjustment you will see that after that wire is removed the cap can be removed to reach the setting adjustment. Two 13mm spinner wrenchs are needed to adjust the pressure. Once the cap is removed, the top lock nut is loosened and the bottom nut is turned clockwise to allow more pressure before the pop-off valve releases pressure. It isn't difficult to adjust but you should make the increases in small increments until the desired pressure is reached.

Humdinger,

I think a picture is needed to see if we are talking about the same part. The pressure relief valve is the round item with the greenish color. Is this the same item?

Thanks, Ter

I am unfamiliar with the photo of your Bauer. However, it appears to me that it functions in the same manner as the P21 triplex. It appears that the green painted lock nut should be able to be loosened with an open ended wrench. Then you can screw in that flat head screw in the middle in increments to increase the pressure before the pop off valve releases.

Your assembly looks similar to the one in my post above in the lower photo.

I was able to easily get mine to 250 bar from around 205 bar on my gauge. All I did is turn the screw in the center of the green spanner area. The screw did not have a locking nut, but it did have detents. I did not want to mess with the spanner, the simple screw adjustment was enough for me. It is gas powered, so I have to run it anyway, so 250 bar is good enough for now. Thanks.
