Well, I pulled a boner last night when shutting down the shop. I apparently used the wrong shutdown sequence wht the Altaros, and harmed something.
I filled a bottle today, and had it set to 4700 psi (with Altaros Company permission)
Today, it filled to 4000 psi and filled no further. It was operating, but no air was going into tank, and the manometer was not registering any pressure. I shut everything down, and went over it. Nada!..Later tonight I did a more thorough check, a found the clear line, (Low-side air to High-side had come loose from Hi-side. No biggie. Re attached. Yea!!! simple fix, only still not working.
I have written Altaros for possible answers. In the spare parts, there is a High side seal, but not for low side. I had requested a complete kit, and offered to pay for same, but no low side seal. (But there was no charte either. just parts as shipped.
I have a new scope coming tomorrow, an Athlon Argos first focal plane that has been ordered for a while. I was very anxious to instal it and give it a real workout. Grrrrrr!!!
I will keep every one informed as to how it goes, as customer service is very important, especially as it is VERY long distance.
I did not find a cure in the manual. And although if talked about a possible fix with a valve, there was no such valve on the exploded drawing. Grrrrrr!!! Nor is the proper shutdown procedure in the manual. I have been going by what I saw on their vid. But disconnecting the air first seemed a bit rough, and made a clunk inside the unit when ever I disconnected the air line at full pressure. I was looking for a bit more gentle way of doing it. Apparently, while tired, I screwed up. Just don’t know exactly how. GRRRRR!!! :sadn:

Thanks for the filter tip guys.
Happy Thanksgiving to all .
I second the part with the desiccant filter’s inlet and outlet, good eye, knife. Otherwise, nice setup and one damn powerful compressor at your work!!! :suprisedn:
Filter inlet on the lower side and outlet on the upper side as should be done with all water/oil filters for the simple reason that potential liquid accumulations (for whatever reason they occur), will follow gravity and come to the lower point of the filter.
If the outlet is on the lower side of the filter, then you blow the liquid out and into your booster unit. If the outlet is on the high side, the filter would have to be full of liquid before it gets blown out.
Cheers
Looks Good! I would sure like to see the final filter having the filter turned to where the air to the Altaros was coming out of the top. Not bottom. A final precaution, and it will make the sieve last longer.
I ran my compressor without a reg. Tonight, and it filled the 88 cfm bottle at a rate of 875+ per hour. Before the last bit, i timed it and it was giving between 875 and 900 psi per hour into the tank.
I am VERY pleased with this little Altaros unit. LOL It still gives a little smile on my face when I have to double check to see if it is running when the Ingersoll Rand is running. Never had to do that with the Shoe Box. Dayum clacking can run you Nuts! But the shoe box does a fine job, and was very happy to have it!

Very well said Hoot !
Air volume rules!
:hoot:
Very impressive!
Most importantly…it shows that an air pressure booster is only as fast as the air volume/pressure it is fed. The Altaros is working as it should, given the air fuel we can afford to supply to it in our homes.

and this was my set up at work .
Placed the filters on piece of board to make things more easy to handle .
I’ll look at ways to make this set up more compact and placing it in a small luggage wheel cart .

This is my home compressor

Sorry guys,I missed some of your comments ,and thanks again for your inputs .
My home compressor (Alltrade 5hp) is rated 115psi.
I don’t know what CFM that would be .
Here are some pictures of the set up,with the filtering that I’m using .
Wilkerson filter/water separator => Wilkerson Coalescing filter =>Molecular sieve moisture trap=>Altaros
When I did fill the guppy tank at home,it took a bit over 1 hour to go from 3000 psi to 4200 psi ,with the comp. running on/off for 40 seconds ,and the Altaros strokes were slow compared with the one on their video (altaros) .
None the less,the job was done,although to 4200 psi because I had to go to work at that time .
Last night,I took everything to my work (altaros/hoses/filters/tanks/etc.) to see what was possible when more air volume was available .
My work : CNC Molds Manufacturing-Industrial compressor’s output=115 psi (this compressor provides air for more than 20 cnc’s machines and the whole shop) .
Now we are talking !!!
Fill the same guppy tank from 3000psi to 4500psi (the altaros stop at that pressure) in 30 minutes,and the booster strokes were a LOT FASTER than when I run it at home .
The air intake screw was fully open.
Zero water content at filters .
At home,there was very little water presence at the wilkerson first filter,and zero water at the altaros water separator.

Papa;
I’m lucky. although my Ingersoll Rand compressor is only being run at 60% off and 40% on, it is rated at 100% duty cycle. However, I tried it, and the elevated heat caused much more water production showing in the plumbed in water separators. I will probably increase it to 60 on, and 40 off, and try to raise the cut on from 90 psi to 100 or 110, and cut off from 130 to 145 psi. :winkn: This would be much closer to the listed Max efficiency listed for the Altaros, and get me very close to a 1000 psi per hour for the 88 cf scba tank. That would be much better than the Omega, and even purchasing a good Up-right compressor like mine + The Altaros, would be very much cheaper than the Omega or like compressors, with a far greater life cycle before rebuilds. (Pending claims and specs from both manufacturers).
I do run a fan directed at the cylinder head of the compressor, as it likes to get WARM!!! 🙂
The mode in which I have it set up now, (Three water separators, Not counting the one in the box containing the Altaros) and two oil separators + Two desiccant filters, One large, and one fairly small, (again, with the additional desiccant filter in the Altaros case), I am seeing “NO” changing of the desiccant color so far. And have used it about a dozen times to fill from 3500+ to 4700+ PSI.
So this is Two Oil Separators, 4 water separators + a very small one at the air connection at the Altaros. Talk about over doing it! 😛
I also have the High Side Cartridge Filter ordered from DMan. (Uses the same Cartridge as the Coltri Filter), Which should kill Any moisture problems what so ever. 😉

Incredible Pops!!! Took the words right out of my mouth! I was typing the exact same thing when I suddenly saw your post…. :whistle:
Kindly ‘Ol Uncle Hoot:
After some research on the net I found the manual of the Alltrade compressor in question.
It’s announced at 3 HP peak (that might be just before blowing the electric fuse out or startup peak of the electric motor), 1.3 HP running. Furthermore 5 SCFM (142 l/min) output @ 40 psi (2.8 bar) and 3.8 SCFM (108 l/min) @ 90 psi (6.2 bar). I couldn’t find cut-in and cut-out pressure ratings (start-stop pressure).
Rami filled a 118 cu.in (1.93 l) tank from 3000 psi (approx. 207 bar) to 4200 psi (approx. 290 bar), i.e. increase of 1200 psi (approx. 83 bar) within one hour.
Keeping it simple, he filled approx. 160 liters (5.65 cu.ft ; 9763 cu.in) in one hour or 2.67 liters/min (approx. 0.1 cu.ft/minute or approx. 163 cu.in/minute).
This is to be seen as the average during the compressor’s duty cycle (as pressure varies between cut-in and cut-out). To me, it seems reasonable.
I am starting to ask myself though how the manufacturers come to their output statements, maybe I just don’t get something here?!? These might be values with a free air flow, while not under load, what do you think, gentlemen?
In the Alltrade manual, the manufacturer states that a max. duty cycle of 75% shall not be exceeded, but states also that oil-lubticated compressors are “typically rated at 50%” and that if the compressor runs more than that, it can “lead to overheating and will significantly shorten the life of the compressor”.
Therefore, Rami, I’d stick with the 40 seconds on and 40 seconds off.
Cheers
Uncle Hoot is right Rami! Listen to him.
and we do need to know your CFM at pressure. The Altaros works on both PSI and CFM to do the job. It can’t’ do a good job with out both.

the compressor is 5 gallons ,3 HP ,Alltrade Trades Pro compressor(oil)
I have pictures,but ,need to research how to post them.
:hoot:
That’s a lot of horsepower for a 5 gallon tank. I’m curious…what is the CFM at 90 psi?
My 2.1hp 20 gallon oil-less compressor proved not to be equal to the task of giving the Altaros enough air to function anywhere near its max speed. If I were to do it over, I’d get a piston driven, oil lubed, compressor with a larger tank. I worried the hot compressor oil vapor would get into the unit, but I know now that properly filtered it will fill clean and dry air.
The Altaros operational speed greatly depends on how much air you can feed it at high pressure. Knife has a pretty strong compressor, most of us don’t have that kind of equipment.

Did you damage an O-ring??? I would replace every O-ring that came with the kit, even if they look “ok”. There aren’t many parts that can go “bad” in that booster! O-rings are easy and relatively inexpensive.
