If you can find a HP Steel tank you can use that as a air source to boost, and just use the shop air to power the booster.  They have 30 min SCBA tanks available and as you have your own booster you do not have to worry about Expiration dates.  In fact there are 88 cubic foot tanks on eBay for $165 with 2 years left.  Need valves.  if you get one I have extra valves.

Just saying a steel HP tank you only have to buy them once.

The guy emailed me back today and said they ordered adapters from another place and should have them by tomorrow or Friday..

Michael I will be looking into those cause now that I'm ordering one of these I need a tank. Would like to save money as well.

It is going to be interesting to see if this device can shutoff at pressure more accurately than a Freedom8 which is ±300 psi if you're lucky!

My F8 shuts off w/i the thickness of the line on the gauge each and every time, sounds like something might be wrong with your unit.

Give me a call at the shop id be interested in getting one as well to test and resale.

Actually, the pressure shutoff switch has been replaced, twice! I have a better one on order, which should be here in about 10 days.

Hi,
 here is few answers for you:






To wilsonj1018
High-pressure piston function explanation
The high-pressure part works on the displacement principle( not sure if this words “displacement principle” are right, i am not that good in English ). Which means that precise chrome rod ( piston) is pushed into a precise cylinder, thereby volume inside cylinder gradually decreases to minimum and thus creates pressure . Piston does not seal against cylinder wall, instead on start of cylinder ( Towards the compressor center ) is placed blue sealing cuff ( in picture Gakseting cuff high pressure piston ) .
Since the sealing element is located on the other side than where maximum compression occurs,  high temperatures generated by the compression to 300 bar is not transmit on seal and this contributes to a greater blue seal durability.
While in medium compressing these temperatures are not so high and therefore it is possible to put the seal  right at the beginning of the piston.


to  Alan
Control unit adjustable output pressure is not a commercial matter, it was developed and designed for the compressor by us. We do not have exact figure about repeatable accuracy setting of outlet pressure. But in practice, the output pressure is maintained very accurately (often below + - 5 bar)

I will try simply describe how the unit operates.
In the body of the unit is a small piston, whose one side is exposed to the high pressure outlet of the air compressor and when valve on the bottle is open, on the piston wall is the same pressure as in a bottle. The other side of the piston being supported against the disk springs . As pressure gradually increasing in the bottle, so the piston compressing springs more and moves.
On the opposite side of disc springs is screw which adjust outlet pressure  ,  this screw leads through of these springs.
At moment when  piston touches setting screw circuit closes and turns off compressor, if the pressure falls. For example when bottle with pressured air gradual cooling down and pressure drops a little, then circuit opens and the compressor starts  working again until piston touch setting screw again.
 
Since the circuit operates at 12V, so even at very small gap between the screw and the piston circuit does not spontaneous switching and  switch does not really occur until the two touch.
Longitudinal sensitivity corresponds to 0.1 mm = 7 bar. Thus, for each increase of 7bar piston moves about 0.1 mm (0.004 ").
If on adjusting screw is not applied external force and is only prestressed by springs  then switching is virtually always in the same place, thus at the same outlet pressure.
Compression spring also ensures permanent  pressure setting during a time when the compressor is running.

To Dairyboy
 power adapters arrived, now i am waiting for customs paper. Once i got them i will ship it.
So it will be shipped later today, or on Monday.




If you have any other questions feel free to ask.

This is a very interesting unit.... Could it be used to boost the pressure of Helium to fill a 300 bar tank with Helium?.... Normally Helium is supplied in tanks which start at about 2000-2200 psi, and of course you would want to be able to use all of the Helium in the tank to avoid returning a partially filled tank to your supplier.... It is a relatively simple matter to use a regulator to drop the pressure of the Helium down to whatever is needed for the input side of the medium pressure piston, but it would still be necessary to drive the large piston with compressed air, one would not want to waste precious Helium by venting it out.... Can you use your booster for this purpose.... or could you modify it for this purpose?....

Internesting shout Bob. I looked over the cutaway photos of the unit, and with a bit of repiping, your suggestion could be a reality. I'd almost buy one, just for the study!

I understand everything I think except the booster running on 12 V DC with that high of pressure being in the high pressure output.

All the 12 volts do is operate the valve.

Alan what operate the pistons, the in coming air like a titter totter changing their directions and the valves open when it is their turn to let it in or push it out?

In a word, yes. It is an interesting device for several reasons. For starters, the only motor is on the shop air compressor. This is good for me, as I have to use a separate feed for the Freedom8, otherwise the fuse blows when the shop compressor starts. And, it appears that one could easily modify the unit to compress helium or nitrogen, yet run the compressor off of air. If it has a drawback, it is the length of time it takes to refill a bottle. But then again, you don't have to stand there and watch the thing run, knowing it will shut off at the set pressure.
