Question about oil-free home compressors

[the_matrix_guy]

Hey, I noticed most of these oil-free compressors in the 200-300$ range are rated for .5 liter tanks. Say I have a 68ci, does that mean I should only fill it halfway? or 30 mins at a time?

Also, do you guys have any recommendations for one around $200-250. It's mainly for target practice and airsmithing. I'm not going to be filling multiple tanks back to back, or anything.

So I have one, and I'm in the middle of adding a water separator onto it. That's going to be the bigger issue and noticed that after doing two 3000 psi tanks in a row. I haven't had a problem filling tanks though. 45/3000 takes roughly 20 minutes, maybe a tad longer. This is literally the one I own, and less than $200 - https://www.ebay.com/itm/318617281024

But I'm thinking I need this water separator with it also. When I used it last I remember seeing more water than I wanted to see as it's just a silly inline paper filter that looks like it was really only meant to catch the water when filling a small 3.5 ounce tank that was built into the gun.

If you find a separator that you like, LMK!

I use mine to fill all sorts of tank sizes. But I only fill one a day and to 3000PSI. Or bumping from 3000-4500psi in preparation for a field day at a friends house. That gives time for me to open up the filter and let it dry out.

I too am looking for a good deal on a water separator.
My workshop is climate controlled and dry and it still collects enough water to be problematic if overused.

I just killed my Vevor. Less than a year. I did my best to abide by the duty cycle with general TLC but it still died. I did like it but I’m sure my filtration and multiple cycles per day accelerated the failure.

I paid roughly $140 with a sale.

So Vevor offers compressors is a huge variety of sizes. The question is how high up the spectrum do you need to go to get one that's not, well, disposable?

This one looks promising...

but needs oil, and an external water bucket for liquid cooling, but has a built in water separator which seems to be the missing key feature on the cheaper models.

So with a 68ci, I should only fill it about two thirds and set it at 3k not 4.5k PSI? I dont need a full fill, it’s just for eating crap in the backyard with the kids

There’s something odd about deliberately buying a tool that you know can’t do the job and instead counting on babying it from day one in hopes that it will last more than a single fill. Its even more effed that the company sells it along that angle…

Making 3000psi out of ambient air will always generate a lot of water. The immediate environment almost doesn’t matter. The fact that water separation isn’t built into the design when it’s absolutely needed sort of outs this company as hacks who don’t deserve your money.

This thing sounds too crappy to exist. If it’s essentially starting to fail the first or second time you use it the thing you should keep in mind is that failing compressors produce debris and that debris is going into your gun.

And I’m in a swamp.

So maybe just get a scuba tank and refill from there?

[the_matrix_guy]

I see the CS2 seems to be highly recommended among paintballers. Seems better than most. I would imagine with a good filter, you can get some decent results and longevity (granted you’re only filling once per day or less.) the CS2 has a premium all copper motor.


on the Amazon reviews, there are people who’ve had it for 4+ years (supposedly).

I too am in the swamp and water WILL be an issue. Athough that would includes ANYwhere hp compressors are used. Maybe worse down here. So if the budget is part of whats making the choice. Make room for a good filter/ water seperator. Im also in the process of upgrading my filteration situation. Keeping up on this system is a must. Theres a few different kinds some lower maintainence than others, but the filter that usually comes with a compressor (a little inline can) would be best as a 2nd stage final drying. Its basically an over sized cigarette butt in there. Also The bigger and more filters you have the longer it will take to fill the tank (cause all the filter cans CIs have to fill with pressure as well).

Small comp your clock is ticking. Bigger compressors would usually be faster and more durable, but heavier, oil to change, and usually a water cooling system. but certaily should be part of your consideration. According myown searchings Vevor (Amazon) swept the market but not nessacerily cause of quality. Tuxing seems good. I use one they now call "Yong Heng" its the blue one and I can say its pretty durable. 4+ yrs not sure how many fills so far, a 68ci takes like 5mins or so (Ill have to clock it one day) for $230 + $120 filter.

Scuba fill station might suit your needs as theres plenty of dive shops in FL. Maybe less convenient when it runs out and its another bottle to rehydro test. But might be enough air and convenience to do what you want. You could always get more suba tanks if you feel one isnt enough. But all the cost of refills and rehydros will add up over time where the compressor might pay off.

Overall Id vote against using the small compressor seems like a gamble and it takes too long to fill, and you kinda want to monitor as its filling. Waiting a half hour or so is absurd IMO. Depending on the filter that might max out its run time. Im content with my setup so thats all I can recommend. I guess it depends of what kind of smithing youre doing. If its like some of the ones I work on that leak out of everywhere and need everything Youll go through a scuba tank pretty quickly.

Is this the type of filter you add on?

I use this one and it’s on sale.

I use this bad boy
$300 plus $30 amazon warranty

Fills a 48/3k in ten minutes with autostop

I work on guns every night and a half hour of filling tanks on the weekend keeps me going just fine.

I don’t run it for more than a half hour to keep it from getting waterlogged


The liquid cooled ones seem like overkill, and the smaller ones ain’t built for this life
