Air Compressor for New Gauntlet III

[3Deep]

Hmmm good post here, if my old piston cup goes out I might get a rotary screw, not ever using the screw type compressor I might not know what I'm missing, then there is the space problem I might have or can this type compressor sit outside? which mine is now

Also, my piston compressor is voice activated. As in it will only come on as soon as I start to talk to someone. 

That is classic! 

I honestly don't know how you guys do it that have compressors by your "general areas". We have ours in our basement(Mike, Alan, Eric, and anyone else down south, that is a structure built in the ground under your main floor...  ) the only time you hear it is when it initially kicks on and vibrates the conduit feeding it!
+1 for basements! First time I've been able to say that!

i've played live music in many of these fabled basements.

Just like Homer.. rotary for primary, piston for back up.
both tanks are piped together, so the rotary turns on a few times
everyday. Super quiet...

$400.00 for an annual service on our 20HP BOGE Screw. I think that is pretty minimal outlay for "almost silent" and cleaner, cooler air compressor. I still have my two piston compressors, they are connected and their tanks used for air storage, and in an emergency can be turned on, but this BOGE unit is built to run nonstop, even though it doesn't have to do that here unless we run our DB and the GT3 at the same time. I have a million air leaks in the old DB so it draws a lot more air than it needs, gotta get that part fixed. You won't regret going with a "good" quality screw compressor, that is for sure! What I love about the BOGE, it's a family owned corporation, German engineered, but locally stocked parts for everything in Atlanta. And we went through a compressor contractor in Tampa so, if we needed support, its' there. He's ironically here right now doing the annual service

for anybody still looking, we bought this as a backup to our rotary Atlas Copco. It is 10HP, 4 cylinder beast. Don't let the picture fool you, the thing is really BIG. It is rated at 35 FFM so should handle multiple presses without much of an issue. Best part is, it was $1,900 delivered!

Rotary VANE, low maintenance high price, years of service.

This is what we run. 50,000 hours of run time before you have to touch the internals unlike a traditional rotary screw. Picked mine up used for 3500.00 5 years ago and its been flawless. I had one breaker go out in it a couple of years ago and it just runs. Not as quiet as some of the IR or others but it is way quieter than a piston.

If it's in the shop near where people work - rotary screw / vane.

Look at the used marked, I got a 15hp Chicago Pneumatic for $3800 that had less than 5K hours on it a few years ago.

We have a Atlas Copco, expensive but worth the money.   Also very quite.      We run two automatics on it.
Not worth spending a lot on a press and saving on a compressor.

Amen to that brother!

Got a chance to pick up a used rotary for CHEAP, but I'm dreading having to go discuss it with the others.  Even though it's damn near free, this is the exact type of thing that the other decision makers here can't fathom for some reason.  They have a hard time believing that someone is willing to do us a HUGE favor and that I've been able to establish some really meaningful relationships within the industry.  I'm going to take a break from running the press, go let them know the awesome option we have and hope for the best.

And, I had strep throat most of last week, took the antibiotics for 3 days then stopped, like a damn idiot, and now it's back.  There isn't much worse than running a press for a 900 piece job with a 102.5 fever.  Walking around with a mask and latex gloves on, thank goodness it's cold out here.

Hey Alan, just for giggles, we wanted to see something yesterday, we tuned the compressor off, after it filled 1 of our 80 gallon tanks. Ran a 4 color design for 237 shirts before I went back over and turned it back on. We could have gone more, but when I noticed the air cylinders moving a little slower, I didn't want to push it. That press literally sips air.

[Admiral]

That's the way to go though Alan.

Now just have both wired up and piped properly to have the backup ready to go whenever needed.

We originally had a 7.5hp recipricating, now the 15hp rotary screw, both wired up separately but piped to the air ready to go.

As for using the extra tank - I don't think I can do that with our setup because it would go the wrong way through a second dryer - does that matter?  The 15hp we run every day has a built in dryer, the 7.5hp Champion has a separate dryer after the tank setup.

Our air rig. The main day to day is the blue  BOGE 20 HP rotary screw compressor, then prevost air lined to our old IR to use it's tank for storage, and then jumping from that to the old US General to use it's tank. Both of those units are powered up in case we need to use them for back up, then to a 240cfm Boge chiller, then we have the prevost air line ring that goes as a complete loop around the roof deck with several drops in place for future use, that pipe is really nice!! Expensive, but nice! It's a nice solid system, we never worry about air lol.

[Admiral]

Very cool setup, no need for a tank with the rotary you are set with those 2 tanks!

I'm thinking the future install will be the chiller AFTER the integrated chiller on the rotary screw compressor after the Champion 7.5hp rotary, kinda like your setup.  This inline setup makes a lot of sense, I'm not sure how bad / not possible it is to send the air the wrong way through the chiller?

That is if it's off since not needed - just used to go to a tank behind it.

From an engineer friend that designs these systems for bio-pharmaceutical labs.

FWIW we have a 7.5hp Kaeser and a 25hp Quincy we bought when we got our new press.
Both are hooked up but we run the Kaeser for energy/noise savings and have the Quincy
in case our demand is ever too much for it. Hasn't happened yet.
