Dry Air ?

T3PRanchA Freedom 10 at 10CFH with 125psi recommended input will take at least 8 to 10 hours from empty I would imagine.

What!? That is insane! Who wants to listen to two compressors running for that long!?

The option is a self contained compressor ... about $ 3K for a Daystate Compressor. 75 cu/ft in 25 minutes according to AOA

Even the Omega systems from AOA are only about 22 CU/FT per hour so a 100 CU/FT tank from empty to full is about 5 hours.

I remember seeing those "expensive" standalone compressors. I have no idea why they cost that much though!? Supply and demand maybe!?

Re purposed from Diving Gear which has always been expensive.

I see...

Still, from what I can tell, there is nothing inside a compressor that justifies the price. Correct me if I am wrong, but isn't it just a few cylinders that move up and down!?

A compressor that reaches 4500 psi is not just a couple of cylinders that move up and down. As evidenced by the mrodair chinese compressor, cheaping out on the materials and workmanship will result in a compressor that is unreliable and won't make pressure without constant maintenance (if it ever does at all!). I have a Daystate (Coltri) compressor and it is WELL worth the $3k I spent. Also, JMHO (and others opinion as well), that diablo air filter is not an effective or safe filter.

I pay $10 to get my 2 scba tanks filled to 4500 psi at a local firefighter supply store and they last me a while. It put me off buying my own compressor when I saw how quickly they filled the tanks (seconds). The store is 5 minutes drive. I can be there and back far quicker than filling with some of the cheaper home compressors.

I disagree. I know what machining cost. Anyhow, this is not the right place to discuss this... : )

EDIT: I agree on going cheap is not the best route at times...

Even though I'm just getting started I completely agree. I just bought a " Great White " and as long as you have a place close to fill it is minutes why buy a compressor.

Thanks for all the great help and advice. I still have to check around where I can get a tank filled before I order.

 

[EXZIVER]

"fsa46"Where do you get your " dry air " from and what to they charge you to top it foo ?

This is my setup.. Some may say it's a bit over kill but it's dry. At least dry enough for me. It's just another option incase you decide to build your own system. Good luck in what ever you decide to do!

i havent timed it but with 45 min scba it takes around 1.5 hrs to fill to 4200 psi from 3000 psi

Thanks for all the replies.
