Electrical compressor wanted, low flow, to around 400 bar
I frequently charge accumulators, normally directly from a nitrogen bottle. Most industrial users keep only 150 bar bottles. I've used "intensifiers" by Haskel and Sprague which do a perfectly satisfactory job where air power is available. I've used 400 bar bottles, but they are frequently difficult to obtain.
I would like to find an electrically powered device which will meet this need; it seems it would be common, but I have failed to find one at all. The consumer market, paintball, typically will use the Haskel air powered units.
Are any readers here aware of such a unit? The needs are not for high flow or high power; I see 1/2 HP (400W) as more than sufficient. I want it to be portable, 25 or 30 pounds (10-15 kg).
