30MPa compressor - has anyone tried one of these?

I had one for a while. One of the retailers in SA brings them in. Bought one as a backup to my bauer and as a portable/travel unit.

Seemed very solidly built and worked really well, except that it puts out quite a lot of moisture that I didn't trust my extra desiccant filter to completely clear out. It pumps quite slowly and very quietly which is probably good for longevity. The air cooling fans blow like little hurricanes though and are probably the loudest components. They work though and the heat sink are only warm to touch after filling a 500ml buddy bottle.

The 5min time is about right for a top up. Never filled anything from empty but 12min shouldn't be far off.

The one I bought I passed on to a friend who has been using it for about 6 months without any issue at all.
 
All Y'all needs to keep track of the power used = Watts!

A YH is about 1800 watts and a 12V unit is 1/4 or 1/5 the effect (360-400Watts).

No wonder it only needs 2 tiny fans to stay cool, unfortunatly it will work all night to fill a sizeable SCUBA tank to 4500psi! Any guarantee for that???

I would bet an eye and say that a 1.8kW YH yields something like 500-600Watts into actual filling of air into the tank. The rest is wasted as heat in: Motor, Compressor and residual heat in the air pumped into the tank. Thats why you need water.



No such thing as a free lunch!!!

Look at the massive fan and stacked airtubes between stages on a Bauer. Thats how they dodge the water! Lots and lots of air.
