upgrade compressor?
Posted by Johnny1000 on Wednesday, July 26, 2017 11:51 PM

Hello all

Apologies if this has been overly covered. The relevant search terms ("compressor", "tank") don't really narrow the field much on these forums...

I have a Paasche D500 compressor with the regulator/moisture trap. It's basically fine: it kicks in here and there as you'd expect, the pressure drops a few when you engage the airbrush, but generally it pushes out reasonably clean air in a somewhat predictable manner. I don't really have any complaints that I can attribute to the compressor and/or rule out operator error.

However... lately, I've been coveting a tank, not sure why. It seems like the primary benefit is to even out the fluctuations in pressure? If so, are those fluctuations a big deal? Are there other benefits?

So, my question at this point is: trade in the existing compressor for a more featured model (prolly an Iwata smart jet or similar), add a tank to the compressor I have, or don't worry about it? (If the middle, I have plumbing questions, but we'll save them for the moment.)

If it makes a difference, I'm using a Badger 105 pushing mostly Tamiya and Mr Paint.  

Thanks!

Johnny, Hi, I had the same compressor which I used daily for about two years, but than it got less than dependable, so quit and went back to my harbor freight two gal. pancake. It will build 125# of pressure and be dialed to what I need to meet my brush needs.It's a little noisey but charges quick and will hold for days.For $59.00 it's never let me down. keep on modeling , Aardvark

I too have a harbor freight 3 gallon $60 buck compressor.  Works great, consistant pressure, just noisy.  With a 20% off coupon its a deal.

In my opinion, if you are getting good results, don't bother. A tank would reduce the starts and stops of your compressor and cool down the air and make your moisture separator more effective, but in tests I've done I can't see any difference in airbrush function.

Thanks so much Don, that's really helpful. Smoother, cooler, and drier all seem beneficial? I saw on your site that you run your compressor into a tank, so that must have some positive role. Just not enough to bother going out of your way to add?

And thanks Aardvark and Route62, I'll be sure to check out the harbor frieght offerings.

cheers

The tank was an experiment.  I have since torn it down and just use my Badger TC-910 compressor.  Thanks for bringing that up.  I will add a comment to the page.

Thanks Don. I reread your posts on compressors and the review of the Badger.

I'm still considering adding a tank for better regulation and moisture control, but am probably not going to worry about it much. A 1 gallon tank isn't all that expensive, and I'm an experimental fellow, so I might still just do it in the name of science.

You could plumb your compressor into a 3 liter coke jug for a one time experiment.

A couple of years ago I changed from years of compressors with air tanks to a quiet Iwata compressor (tankless).  That little compressor puts out a very pronounced pulsation.  I was apprehensive, but found absolutely no effect from the high frequency pulsation. In fact, I found most of the pulsation I felt in holding the brush was mechanical vibration carried over from the compressor down the hose!  However, with no tank I am sure the air has some pulsation.  However, the high frequency of the pulsation, compared to the velocity the airbrush is moving during painting, has no effect on the spray pattern.

Comressor tanks are a military industrial complex conspiracy to shake us all down... I knew it!

Or rather, I didn't.  But I'm going to stop worrying about whether or not my compressor is somehow deficient in ways that I am not yet able to detect.

Thanks all
