Hiya hoot glad to hear you found the source of the leak it scared the crap out of me.To hear that high pressure hiss next to my 88cu ft tank :angrymob:
Consider using some dessicant filters before the Altaros as a final defense against water still suspended in the air.
Water seperators can only do so much and then the dessicant gets the rest.
Happy Boosting Bud

The “Black QD Male Fitting”
This little rascal almost tricked me into buying a new QD female fitting!
I thought the sudden air leak was coming from the female QD fitting until I read Knife’s post, and sure enough the little male black QD fitting had come every so slightly loose, Consider that at the high output pressure end of the Altaros unit, it doesn’t take much “looseness” to dump a LOT of air, and when you feel the connection it seems the air is coming out of the QD female end…but it’s not!
I put some ‘Blue Loc-Tite’ on the threads of the black fitting and snugged it in as finger tight as I could get it. That little fitting is plenty light, and I suspect it’s either aluminum or some synthetic, so don’t use any mechanical force on it because you will bugger it up plenty!
Also, I needed to adjust that air flow setting because my Husky 175 psi 20 gal was running full time. Now it is at 60/40 ration on run time…takes a bit of doing because there are no markers on that set screw and it’s a bit of trial and error to get it where you need it for your specific compressor.
I’m thrilled with the Altaros unit…it’s doing it’s job just fine and running as cool as can be. BUT…water in the primary compressor is present in spades so I have two water/oil filters in-line with the outlet hose on the compressor before the air even gets to the Altaros moisture removers. These little things are fairly inexpensive and it will pay big dividends in keep moisture out of the Altaros unit and out of your gun’s air cylinder!
Remember…a bit of easy off ‘Loc-Tite’ on that little black QD fitting and that should put that problem to rest permanently.
That’s all I know…off to bed.

PS: Knife’s wife is right…he only looks stupid!!! He’s saved me some money already.
Good Stuff Doc!
I do find the larger cfm capability of the upright, is doing the job faster, even with a lower cut-on setting,
So far, I am getting well over 800 solid psi per hour. The newest freedom ShoeBox can do 500 per hour, while the original was at 250 psi per hour. So with proper input, the altaros is definitely quite a bit faster. As you can see below, increasing the cfm out put of the main compressor to twice the cfm, it at the same time, cuts the fill time in half! 🙂
I filled the 88 from 3700 psi to 4800 psi in 1hr 15 minutes.
So far, it looks like original 250 psi per hour/ max recommended 85 psi input per hour
Freedom 10 sb 500 psi per hour/ max recommended 125 psi input per hour
Altaros booster pump 880 psi per hour/ 90 cut on, 140 cut off upright with 11-2 cfm @
90 psi. as per manufacturers specs, and the upright cost no more
than the much smaller, less capable oil less units.
If connected to a true dual stage shop compressor, with sustained 145 psi input with at least 11 cfm output, the fill would be impressive indeed!
Please forgive my next to last post. Just corrected it. Up all night, and was obviously not exactly coherent! :rofl:
Knife
I’m really liking this little unit. Very impressive!
No problem bud figured it’s good info for us airgunners :biggrinn:
This is just my preliminary testing but I think lowering the psi into the Altaros to about 100 and increasing the flow will yield better results in my case.
My compressor has 175 psi of storage and kicks on at 130.
The fine balance is in that small flow control in the Altaros you got to keep the flow slow enough where the compressor still gains psi over the flow into the Altaros so your home compressor can rest.
With any compressor though but worse with smaller ones alot of moisture is created so honestly that small dessicant filter in the Altaros is not enough to keep the air dry in your tank.
So far I have ran it about 14 hrs… I’m very impressed with the Altaros. Great option to fill your own tanks for sure.
Hello Doc, I’m the guy who mentioned the Husky 175 psi 30 gallon compressor. I’m considering that exact hook-up that you have, tank and all. You answered all of my questions, so thanks for posting. Although the 4 hour fill time is not so bad, I was hoping that the thank size and the175 psi fill would put a bigger dent in the fill time. I really didn’t want to go larger than 30 Gal. or spend a lot of coin on a compressor because other than using it to pair with the Altaros, I have no other need for a compressor. Maybe 4 hours will have to do :sadn:
Thanks again for the info :8:
Hey guys glad I found this thread. I also own a Altaros Compressor Hey knife !.
We have a pretty huge thread on this booster/compressor on GTA forums.
I was reading through the posts and someone mentioned the Husky 175 psi 30 gallon 5.1 cfm at 90 psi compressor.
50% Runtime 50% Off as per my compressors recommendations.
I have this compressor and runs great but won’t be as fast as a huge compressor of course.
Lower psi at inlet but higher cfm might be the ticket to faster fill times. Maintaining the 50% off and on for my compressor.
More testing to be done.
Moisture is a big problem and have it setup with moisture seperators and dessicant filters I made myself.
Really like It! . In my testing I did 4 hrs 14min to do a 3000psi to 4550psi fill on my SCBA tank 88cu 60 minute SCBA
Here is my post from the other forum you guys might find useful.
Total time 4hrs 14min to fill from 3000 psi to 4550 psi.
Carbon Tank 60 minute cylinder 88 cu ft
145 psi is max at inlet to Altaros cut in from the compressor is 130 psi. So a bit of time off regulator and cut out is at 175 psi.
Compressor setup 50% on 50% off just like recommended in my Husky manual. About 7 minutes of runtime on and off. Took a bit of time with the regulator on the Altaros to get it even but hey I like getting stuff close to perfect. My Husky was howling lol !
I was In the garage all those 4 hrs making sure everything went smooth. I will tell you what I got startled bad anyone with the Altaros compressor please check that black metal nipple at the outlet of the Altaros, I didnt know and last session that little piece came unscrewed a bit so when I was pre charging my Diablo filter at about 1000 psi I got a huge hiss!!! Stopped everything and disconnected the foster fitting and found that little black piece unscrewed. So please check yours.
After boosting went to check my dessicant filters as you can see about 25% of it was discolored that’s the entry of the air so rest of the air perfectly dry.
Even after this the Altaros has another water separator and a small dessicant filter that I haven’t checked yet I will assume dessicant is perfectly colored in the Altaros.
You can see total overkill on my water seperators I have access to these as I am a Industrial Mechanic.
You can use just one like I did at first but my complete first stage was discolored so I overkilled it so I wont have to recharge so much dessicant on the stove.
I truly love this booster works great ! $600 bucks it’s a steal compared to the shoebox which I was totally considering until I seen dairyboy’s review and seen the potential. Shoebox also a great machine from what I have been reading just different approaches.
You can use any workshop compressor but moisture is a problem like I said before and depends totally on your compressor. Smaller the compressor the longer the fill time will take.
I recommend totally some type of dessicant with water seperator setup and test to make sure it’s not all discolored and letting wet air through to your scba tank or pcp gun.
Again sorry for the long post grammar etc… Just want you guys to have complete info before making a decision. Those with shoebox what was your fill times 3000 to 4500 psi ?
Thanks guys now we can make some time comparisons.
Good looking little unit! But even my upright/11.5cfm@90 psi gets a workout!
And the Altaros does not’ require an oilless compressor. You can get a lot more for your money in a standard upright.
Check out the offerings at Tractor Supply. Much better price than the Home Depot and Lowes. And Sears is ALWAYS over priced, and of lesser specs. 😉

Google the Dewalt D15546 compressor. It is oilless and puts out 5.1 cfm at 90 psi. They can be purchased for $269 online. Besides its generous output capacity, another benefit from this compressor is that it runs much quieter than most small compressors. It is rated at less than 80 decibels when running. I used to have a Shoebox and originally mated it with a Porter Cable pancake compressor like Hoot has pictured in his set up. Whenever it cycled on it made me jump. It’s rated at 93 decibels which is LOUD. If you’re going to have a nice, quiet running Altaros it is a nice benefit to buy a compressor that won’t scare the crap out of you when it cycles on. Anyone who owns one of those small and loud oilless compressors knows how annoying they sound. I have a Rolair JC-10 which is super quiet but it only puts out 2.6 cfm which is not enough to pair up with an Altaros and get decent fill times.
I own a Bauer 5000 psi compressor. However, I follow all the newest entries into the airgun compressor market with interest. IMHO, the Altaros is a fantastic value and is a serious contender in the affordable compressor market.
Small update. Increased the input cut on for the main compressor by 10 psi. Now at 100 psi for the Altaros.
So far, the water separator is working just jine, but I do have additional separators coming off the main compressor.
Knife
This compressor sounds like it might be “the one”. How well does the moisture separator work?
Ran a preliminary fill test Sat. Morning after a shooting session with the .257
Results as follows;
Tank being filled, 1 hour, 88 cubic foot Scott SCBA bottle.
-Pressure in bottle. Slightly under 4100 psi
-input pressure from 11.5 cfm at 90 psi, with reg set at 110 psi.
-Used the Altaros booster pump to fill the bottle to 4700 psi.
-Time for fill, 45 minutes for a 600 psi fill. So it look like it will be apx 800 psi per hour at this fill pressure. Need to up the cut on point for my up-right, as it drops to 90 psi before coming on.
My Chain Drive Shoe Box unit, (one of the very early units) gets 250 psi per hour. 3X 250 is 750 psi
At this point, with current settings, the Altaros is a little over 300% faster.
I understand the newest ShoeBox’s are similar in fill time to the Altaros. (at double the price)
More testing to come.

So far, sure seems so! 😉

Nice one knife, really good to hear it works as it should. I can imagine all of those nimrodair owners sitting in the corner of their garage cursing the damn thing.
And Sincere has some serious competition on the market for sure, this is good news for all airgunners, both sides of the pond.
Happy shooting, with all that air.

I know someone will ask, so Yes, it is very well packed. The unit is light, (apx 11 lbs.) efficient, and looks very well engineered, and assembled, with a nice finish.
It arrived in 6 days from country of origin. No dents, dings, or scrapes. Nothing to complain about here! All U.S. fittings required were supplied, along with proper power supply for our outlets.
I plugged in the power supply, attached the usba bottle, opened the valve of the main compressor, and then the usba, and the unit started instantly. Once the foam was placed where recommended in the Altaros Vid, the only thing you really hear, is the light sound of a guinea hen. Almost like a squeaky hinge. Guess that is the air making the noise going thru the valve. I’ll find out. I do know, that when the shop compressor was running, I couldn’t hear the Altaros unit at all. Had to check the dial at the end of the unit to be sure it was working.

Hi Doc!
Yeah…made me angry because I was trying to find out why my K-valve yoke filler was leaking at the O-ring in the valve. I never found the reason for that leak…replaced the O-ring, still leaked. Couldn’t find any cracks or problems with the yoke or valve???? Oh well…
Then the “leak” developed at the Altaros QD connector and I just about pissed myself! Fortunately I came inside and read up on what was happening and found Knife’s commentary and found the fix.
I am looking at desiccant filters on-line. They can get expensive, but I agree the mechanical filters can only remove so much…then the desiccant kicks in.
If you fill your tank outside in a humid environment, I live in the mid-South, it is amazing how much water drains out of the compressor when I empty it when I’m done filling. (always do this!!!)
The Altaros is a work of genius and I feel it is well worth the cost. Now…if I could only find out why that stupid K valve yoke is hissing at me… 😐
