JTS COMP1 Portable PCP Compressor Reviews

The speed of filling and its cooling system. This is a replacement from the first one. It had an overheating issue I suspected a bad heat sensor. Pyramid replaced it with no issues. This one is working as expected and very happy with it

I wish it would have a temp gauge on it so you can see the internal temp

Pyramid air is a good place to shop and they are always willing to answer any questions you may have and the are very knowledgeable

very quiet compared to others. it also separates water from the air. i regrease the cylinder after every 400 to 500 uses. i've had it for 2 yrs. now and it still fills perfectly for my avenger and flash qe. great little pump!!!

nothing

It's quieter than the others

Put in a digital temp gauge and make the charge hose at least twice as long

At first it filled my Impact M3 tank good. But later on it was getting weeker. After a few months of light use it started shutting down after about 3 minutes of use and then I would have to let it cool down and start it again. Sometime I would do this 3 or 4 times for 1 top off on my pcp. I filled a claim with PA they acknowledged the claim and sent the info to JTS and haven't heard from them even tho my unit was still under warranty.

It would be nice if JTS would at least contact me! I don't think a compressor like this one is very durable. It needs to be water cooled.

Spend a little more money and get a compressor that is water cooled.

Portable, quiet,

Done more research and not bought it as a main full time use compressor.

If you're buying this as a backup in the field to use every once in awhile you probably won't have many complaints. I used mine quite a bit and within 2 months the Piston seal was shot, I put the replacement in which was quite easy but I don't think it's going to hold up at the rate I use it. In hindsight I wish I would have put my money towards something liquid cooled with oil as a main unit and maybe bought something similar to this for a lot less money for occasional our emergency use.

Purchase this as a backup,
or just an occasional use compressor or stock up on a lot of extra piston seals if you're going to work it hard.

Been trying to contact jts for extra seals but contacting customer service seems to be hit and miss, going to look for an aftermarket higher quality seal since apparently they don't want me to buy one from them.

Everything. Extremely quiet. Can fill in your kitchen on the table. Went from 1400 psi to 2800 in such a short time I didn’t get a chance to time it. Shut off at the correct pressure.

Make it cheaper

Very very light. Don’t waste your money on those cheap Amazon products go thru pyramid Air.

Very quiet compared to aftermarket comparable portable compressors. Performs well. I added a second water/moisture filter inline, and she works beautifully. Ihas been extensively in last 2 months, Stays cooler and no issues so far. I chose the JTS unit over the Rovair because of its proprietary cooling system.

Noting at this point. Maybe a slightly longer air hose so I don't have park unit so close to port all of the time.

At this point in time it's a very good choice depending on your budget. Does the job for a lot less money. At this price the way it performs, if you bought some much expensive equipment because the pro's do it. You wasted your money. I retired and live in the country and don't always like going out shooting traditional arms due terrain restrictions. Heavily wooded and brushy with short to medium ranged sectors of fire. Besides not much fun in short distances with traditional arms not to mention ammo!. So I don't hunt much anymore but enjoy these air rifles. So, you can obtain quality compressors and air rifles for less and get results just like the FX M3 I almost bought and saved a ton of money went with Avenge X Tact with good Athlon scope and she shots just as good as I have seen. Not at all interest in bling. Performance matters.

Works great, very easy to move around as it's very compact and somewhat light. Have used it to fill my Daystate Red Wolf Safari for about a year and zero issues. Must be said I have a custom 700cc on the Safari as well and fills it from 150 BAR to 250 in 8 minutes.

Nothing

I think one of the main keys with any portable compressor that aren't water cooled it to keep fill times short, 10 minutes. I've done this since day one with the JTS and works today as good as brand new

Not using my hand pump. Should have went straight to compressor. 1st PCP, so common mistake I Guess. Haven’t used it much, but works fine. As advertised.

Nothing wrong with anything it does or has on it.

Don’t really know anything different, but compressor works just fine. I have the JTS Airacuda-max in .22 and very happy with that too.

Exelente articulo

Haven’t used it that much, however it seems to work fine.very easy to use. Nice and compact.

Nothing

My AirForce Condor SS PCP Air Rifle, Spin-Loc Tank is in storage many years, because I hate to use hand pump. This JTS compressor works well: easy to use, fairly quiet, short time re-filling and moisture remove.

Just hope manufactory can provide common maintain and service video, so that the machine can last longer.

My tank maxi 3000psi, and I set meter to 3200psi and running re-fill will auto shut off on time. After I shot about 30-40 and the pressure will drop to below 2000psi, then I will re-fill the tank, most time 4-5mins enough. I hope this using style can make the JTS last longer. I think long time running at once will not good for the machine.

I like it better than BOTH my Nomads... QUIETER - At least by half... FASTER - At least 2 times faster filling... LESS EXPENSIVE - By half... The filling is WAY smoother than my Nomads. My Nomads were not this efficient when they were new... Comes with more tools and seals than my Nomads - READY to fix when it fails... which it will... they ALL do.

Nothing to speak of in a $500 HPA compressor.

I fill my guns 500+ times a year... My Nomads quit on me after that. I have had the first one worked on 3 times (bought in 2018) the second one has been back twice (both out of warranty) PA and AV were great and the units came back in 6 weeks or so. Usually $100-$150 round trip... shipping there and the repair cost. The Nomads took 10 minutes to fill my big bottle guns (Texan CF - Hatsan Pile Driver - AEA Challenger BP .457) This JTS unit is filling them in 4-6 minutes. We will see how this thing holds up... More to come. M

Really nice compressor, quiet, simple to operate and comes with both AC/DC options

Longer fill hose, would be really nice to have at least 36"

Small, quiet and portable. BUT the problems are already starting to show up and I haven’t even used it.

Make the hose and fittings standardized with some other countries fittings, other then a poorly done Chinese version.

OK. Where to start.
First is the quick disconnect Foster type fitting. It’s OD is larger then expected so it won’t clip onto an FX air rifle.
Next is the fitting thread. It’s a Chinese one of a kind reverse “JIC” type copy that uses a 10mm X 1.0mm thread and NOT the standard BSPP 1/8” X 24 thread. Better known as a BSPP #2. So don’t expect to find an adapter to put on the QD end of the hose. The Foster type design is also more shallow then a standard Foster. So if you try and put their plug in an FX fitting it’s loose and won’t seal. Now comes the other end of the hose. It’s not a standard fitting at all. It’s a proprietary design that uses a Durlin seal. So just swapping out the hose is off the table. I have ordered a Donnyfl QD to QD to try and use the pump. At this point it’s a $600.00 door stop that has never run. Save your money because just finished driving 100+ miles going to different shops trying to identify what China made. JTS tech support is junk at best. Avoid this pump.

very quiet and fast filling

nada

good value

All good compresser is quite, fills my bintack and piledriver, fast.shipping and customer service is the best ,they will work with on all levels.shipping is lighting fast ..place rocks the air gun world.luv you guys.thank you for the speeds at which you move.

Nothing only wish you carried aea products.like( bintac.)

Fastest shipping.

Simple operation, works well, fairly quiet. The internal water separator does remove moisture, every time I bleed before removing fill hose water comes out the drain hose, I look at it as thats water that didn't go into my guns, does it remove all the water? that I don't know, but at this price point I'm glad to see that some water is removed. (I also run an inline filter) The auto shut off works, but not the most accurate gauge in the world and its a little difficult to get it to shut off exactly where I want it to, so monitoring it is recommended. A little bag with a few consumable parts came with it, along with instructions on replacing them. I'm filling a wildcat bottle to appx 220 bar and an avenger to a little less than 300 bar, around 20 fills on each so far and no problems, filling the wildcat seems not to stress it at all, filling the avenger to 300 bar does warm it up some.

As of now nothing, would have given 5 stars but its to soon to tell, we'll see how I feel in a year.

I think its important for people to realize these high pressures we use are really hard on equipment, and rebuilding to some degree can be expected. I've been hand pumping and have replaced several parts and taken apart and cleaned my 2 hand pumps several times and expect to do the same with this compressor and hope the customer service is there for me when the time comes. I'm no expert, but I believe filling above 220 bar like I do for the Avenger cuts down on the longevity of the compressor.

Easy to use and compact size. Ability to use it AC or DC is really handy. Beats the heck outta hand pumping!

So far I haven’t had one hiccup or bad experience with this compressor.

Before I got this compressor, I was hand pumping my Avenger and so it didn’t get as much use as I wanted. Now I shoot every day and use this practically every day and I’m loving my gun more and more. I would highly recommend ordering a bunch of ammo when you order this as I wish I had done.

I appreciate it's small size and ability to switch between power sources. It's easy to use and quiet.

I have nothing I would change, however, I realize that the technology in small portable compressors is constantly evolving!

I bought this unit for refilling PCP rifles in the field. So far, it's doing an excellent job of that, and I'm very satisfied!!
