Clean, Dry Compressed Air

[2manyAirGunz]

Are any experienced and knowledgeable air gunners out there willing to weigh-in on the importance of clean and dry air for PCPs?

I own both the Air Venturi 110v model and the larger Nardi Atlantic P 220v model. I notice when turning them on -- the AV for charging my rifles and the Nardi for topping-off my carbon fiber tanks -- there is initially and wee bit of compressor oil mixed with the compressed air. Here in the Deep South the humidity is extreme and I have no doubt that these compressors are introducing moisture in to my rifles' bottles and cylinders.

Any suggested remedies will be greatly appreciated.

I live in Ok. and feel ya about the humidity. What type of filter set-up(s) are you using? I'd buy the most filtration i could afford. My buddy's Coltri has water sep. tower and final air filter. He uses a tool-quality air filter cartridge(no act. charcoal) and changes it about every 20hrs. Seems to work fine.

Are you using a high pressure filter? I have an Altaros booster and use a coalescing and desiccant filters between my shop compressor and booster and a high pressure filter between it and my tank. I don't get any moisture in my guns.

Currently, I'm using the AV dry intake filter. The Nardi compressor instructions simply recommends opening a designated pressure valve every 10 minutes during use to release accumulated moisture. 

I am interested in the Coltri water sep.tower system you referenced. Any idea where I can find it?

Thanks for you reply.

Yes, on the AV compressor.

On the Nardi that valve you're opening to bleed probably is the separator. On a Nardi the silver square tower holds the filter iirc. Which Nardi do you have? Got any pics you can post?

Intake filter helps, a little. Moisture rears it ugly head when air is squeezed/compressed so you really need a good final stage filter. The Alpha that Joe Brancato sells works great. It ain't cheap but its very high quality. http://www.airtanksforsale.com/AlphaFilter/AlphaFilterDirections.html

Video of a Alpha in use: https://www.youtube.com/watch?v=S2G66k7OFcQ About the 2min50sec point.

It's the condensation valve to the right.

Sorry for the delay. I'm fixing breakfast for my squirrel retriever (JR terrier) and myself.

I appreciate the links. The "alpha filter" is now a must purchase for me.

Thanks again.

AOA is selling final stage filters. The issue at least for me is how do you know. I've got a daystate (coltri) compressor and a final stage filter but essentially we're working on faith that the air is dry enough. I guess you do the best you can and deal with the results. At some point enough is enough. Adds up to a lot of money for sure. And you're counting on the products purchased to do what they claim they do.

I asked about different desiccant awhile ago and got really good response.

You do absolutely want dry. Tons of good information on here ( & links to values , thanks y'all) .

I do NOT recommend this idea but have thought perhaps for all the $200 compressor folks who may not spend the big bucks for dryers/filters - not this model-

I remember a shop with as booster 30+ years ago that had oil ( silicone naturally ) injection and it seems one of the smaller compressors ( the AV ? ) adds silicone oil.

The old career airguns were HEAVILY lubed ( as in preserved not the tiny amount one woulod use in a shop setting) inside the air tubes this way and I dont think anyone has ever seen corrosion inside a career?



As people will save money the right way or otherwise I dont see this hurting anything, might help? Naturally NOT if running a dryer.

"Which Nardi do you have? Got any pics you can post?"

The Atlantic P 100 

 

[Stefanjan]

That filter in the link is only 135 psi max. It will blow apart at our hpa pressures 

 

[2manyAirGunz]

Which filter are you referencing?

The Alpha filter system sold by Joe Brancato?

That short cylinder must be the filter. Never seen one so short Pic of a "standard" Nardi:

 

[gadballs9]

More: i think someone other than Nardi built this. I mean it IS a Nardi compressor with what looks like a Nardi separator but that little stubby filter looks kinda home-made. I'd replace it with a JoeB. Alpha. The big square Nardi will be far more expensive. Are you in the States? I'd call JoeB. and send him pics for his opinion. He knows far more about this stuff than me. You've got a nice compressor. Just need a good filter. Good luck.

That Nardi compressor sure is purdy!

"That Nardi compressor sure is purdy!"

*And sturdy and quite efficient as well as reliable.
