Bauer Junior II compressor

This is an item that I really wanted to get aboard the previous boats but opted to forego due to space constraints, but with the large dinghy garage aboard Zanshin I finally have the space and access that I'd like in order to easily use this dive compressor, not to mention have the space for the requisite dive tanks. While there are several manufacturers of dive compressors on the market the German Bauer company has a well-deserved reputation as being reliable and sturdy and by far the most portable compressors are made by Bauer.
I opted to get the 220V 50Hz compressor sourced through the USA subsidiary as I wanted the compressor during commissioning and that process went quickly and smoothly, although the packaging made the compressor look as if it would take up a lot more space than I thought I had available. I chose the compressor which could be switched between normal and high pressure fills and my two dive tanks are also certified to high pressure. What I neglected to consider is that the regulators also need to be high-pressure certified and I got normal ones, so for the moment I am using normal pressure on the high-pressure capable components, stressing them only lightly and hopefully prolonging their life span.
The compressor lives very nicely in a storage space underneath the bunk in the forward skipper cabin. When in use it heats up quickly, so I ensure that the hatches and doorways are open to provide adequate ventilation during the fill process. The two hoses for condensate plug into a 1-liter plastic bottle and the resultant milky liquid gets poured down the sink, at first I planned on draining to the bilge but this stuff has a bit of compressor oil and that might gunk up the bilge pump.

First trial of Bauer compressor
Filling up the dive tank I was under the water a long time, but most of it at 20 feet or so, so I still had 2000PSI out of 3000PSI left.

Filling up the dive tank
Filling the dive tank Here I've just attached the fill assembly to the tank and am starting to refill it. The fill pressure is 3000PSI and this tank is still more than half full, but the dive I did was at 10-20 feet so didn't require much air at all.
