Compression - Show Off Your Compressor

[bmwpower]

Got me again....have a ways to go I guess before I'm here long enough to read your mind.....

Not in my mind, just throughout this board and others. If you want a quiet compressor, go with an oil lubed one. Heck, go a step further if you may and get a screw compressor with their sound deadening cabinets.

16ft lengths are about $25. It's the connectors that are expensive (can't remember the cost but I can look it up for you); they are all nickel plated brass and are of a very nice quality. It goes together easily and no leaks, and looks good. I made up the aluminum plates that the outlets mount on (6x6 for a single outlet; 6x8 for a double).

The manifold won't freeze as it's in a heated area. I set the drain to turn on long enough to hopefully clear the PVC of any water. No probs so far.

Yea, let me know what they cost, if you can. Going through the motions with the design now and if this system is within the budget, I might go for it.

How come you had to make the plates?

 

[bgott]

My former employer gave me those 2 (defective) screw compressors for free.
Kaeser SX4 and Atlas Copco GA15. With a new pressure switch the Kaeser unit should (hopefully) be working again properly and will be installed in my garage.

Yep, that is a major " YOU ****"!!!

 

[Monte]

oh thanks ! my first "you ****" award !

PS: If you`re looking for a quiet compressor go with a screw compressor (if you need permanently a lot of air) .

There are also piston compressors which are encapsulated like this:

Push-in fittings and pipe etc. are also avail. from these 2 manufacturers www.johnguest.com and www.elkhartproducts.com (TecTite)
Most of the fittings available are made by one of these 2 companies.

has anyone ever heard of lux air or luxaire compressors? i tried to search on google and came up with nothing. someone's selling a 60gal locally and i thought to ask the guru's on here.

 

[RbrtAWhyt]

Your set-up rocks. That aluminum piping looks awesome. Great job...

 

[zepherman]

My brand new IR 60 gallon 3HP compressor arrived today. I'm just waiting on the anti-vibration feet I ordered to arrive. Hopefully by weeks end I will have this puppy up and running. I have to say it's the prettiest compressor I've had, and also the largest.

[RbrtAWhyt]

Congrats. I have to agree that IR is a good looking unit.

 

[e-tek]

That tank looks bigger than 60gals, but maybe it's just the contrast of the 3hp motor. How much where the feet?

 

[Shocker]

Did you buy actual feet or hockey pucks?

Yeah it's most likely the contrast of the 3HP motor. The anti vibration feet were $36.67. They're made by KNC and I got them through Amazon.

Did you buy actual feet or hockey pucks?

I got actual feet for them. I first looked into getting some pucks, but being that I live in the Southwest, no one around here sells hockey pucks. So I would have had to order some online anyway so I figured I'd just get some actual anti vibration feet made for compressors.

Here is my setup

60 Gal. 3 cylinder. From Tractor Supply about 4 yrs ago.

[JOHNMAN]

Here is one of mine:

It is a Champion R15 2 stage, 5HP compressor, a 5HP farm duty 1ph motor and a relatively new tank from Grainger. It used to sit on a tank that was dated 1973.

It works great for me. I recently bought a silencer intake filter and mounted it on anti-vibration feet. It is much quieter now. I still plan on mounting a door on the closet to make it even quieter in the shop.

 

[sauceonside]

We have one of those IR compressors at work for the forklift mechanic. It was installed outside with no cover. With the last few weeks of rain, the motor is starting to get rusty. It must be nice to spend someone else's money and not worry about taking care of the investment.

 

[Falcon67]

Here's my latest:

It's an upgrade from a portable 1.5HP Porter-Cable 25 gallon that has worked without a hiccup for the last 10 years.

You'll note the lack of regulator and pressure gauge. Well, lemme tell ya the story on that - I wrangled Lowes into a price match with Tractor Supply, which has three CHs (same model, etc) on the floor for $399. Lowes has a price match + 10% deal. I was hot for that 10%. The kicker there was that they (Lowes) can't go below cost, and the manager pulled up his cost to check and it was $398.05. Since he went to the trouble and I wasn't getting a better deal anyway, I just bought the thing on the spot. No problem getting it home in the truck. Walked it to the rear of the bed, then layed it down, slid it out some and the wife and I got it on the ground without a problem. Scooped it up with the two wheeler, she opened the back gate...and I promptly hung my foot on the side of the walk and compressor and I went down in slow-mo. Smashed the regulator and the gauge when that part landed on the concrete. It's hard to stop a 300 lb top heavy compressor when it wants to lay down. Total repairs - $46. But I got me a DEAL honey! She was very sympathetic. She's used to it.

I'm working out how to best to plumb the new CH into the existing piping, along with a Hankinson dryer I picked up at a swap meet for $50. I have black iron now, was going to do the new runs in copper but I'd have to get into some rather compromising positions with a torch to do that, so I'm leaning back to black iron.

I also want to build the air separator deal created by Franz - but there's no 2" pipe in the home stores. Well, they have 2" heavy galvanized conduit, but they can't thread it. I'm thinking of trying with 1 1/2" pipe and just making it longer a bit, to get about the same volume in the separator.

For feet, I cut some pieces out of the horse blanket that I have under the washer and I'll put some 4" squares of 3/4 pine on top. There's a nice Hilti hammer drilla t work I can borrow to lock the thing down with.

I better get it figured out - swap meet is this weekend and I need to sell the old compressor to help make up for the tool attach I had last Saturday.

 

[zepherman]

Well the compressor is all wired up, has the new anti-vibration feet, new drain pipe, and is now complete. I have to say it works like a dream and is surprisingly quiet.

Here's some pics.

 

[benjamming]

Here is what I finally settled on back in Jan-09. It is a Champion Advantage Series model VR7F-8 with a 7.5 HP 1/60/230V motor & 80-gal tank. It has a centrifugal unloader. The 'Advantage' portion includes a low oil level guard, vibration pads (rubber), automatic tank drain - pneumatic, air cooled after cooler, & a magnetic motor starter.

I used a 50A breaker & Romex 6 wire. I added an hour meter. It is model MT10 from ENM.

I considered Saylor-Beall model 745-80 but it was about $2k more. Quincy uses some imported castings. IR uses castings from India. With Curtis, you have to go up to the ML series to get away from their Taiwanese pump. CH uses a pump from China.

 

[ironroad 9c1]

My 1961 Ingersol Rand 80 gallon is very smooth and quiet also. It's got a 3 HP125 lb. frame 215 motor on it. 2 stage Compressor is extremely heavy too-very quiet and smooth. This old thing sandblasts for hours and never has failed me in 15 years. Can stand right next to it and talk with no problem. It's this new light weight **** built today that doesn't have long life quality built into it! I don't need any compressor room!
Bob

LOL that looks like the same pump that my horizontal IR has...I love it, Just need a new motor.

For right now though I picked up a mac tools 44 gallon that does pretty good.

The SB 745-80 is a lot more compressor than the Champion VR7F-8 but a SB VT 735-80 (a more comparable model to the Champion) is $2,300.00 compaired to the Champion Advantage Series model VR7F-8 at $2,512.00

[benjamming]

Actually, the 735-80 is a 5 HP & only delivers 18.3 cfm at 100 psi whereas the VR7F-8 delivers 23.1 cfm. The 737-80 would be a more direct comparison if available with a vertical tank. It delivers 22.2 at 100 psi. I wanted one with a vertical tank.

The SB VT 735-80 is a 5 HP vertical model (the one you referenced was not a verticle model) and puts out the same CFM as your 7.5 HP Champion.
Look here;
http://www.saylor-beall.com/air_compressors/tank_mounted_vertical.php

How you can say that a Saylor-Beall would cost $2,000.00 more is beyond me. Bump it up to the SB 7.5 HP if you want that puts out 26.x CFM, it's still less money than the Champion - NOT 2,000 dollars more. The Saylor-Beall runs a little slower rpm wise and that usually translates to less noise but at least the Champion is one of the slower units and I would guess much more quiet than the IR and others that use the screeming 3450 rpm motors.

 

[benjamming]

When I said that I wanted one with a vertical tank that was directed toward the 737-80 model which is only available in horizontal configuration.

The 735-80 (5 HP) delivers 18.3 cfm (23.0 is the # for cfm displacement). So it's not an apples-to-apples comparison. The 737-80 is a more direct comparison but it was not available in a vertical configuration.

Now in regards to pricing, the Champion was $2,669.15 + 7% tax + free shipping = $2,855.99 delivered. The SB 745-80 was $3,527 + $257 (magnetic motor starter) + $81 (low oil level guard) + $98 (vibration rubber pads) + $405 (air cooled aftercooler) = $4,368 + 7% tax + $100 S&H = $4817.54. A difference of $1,658.96. I forgot the tax on the Champion when I figured it earlier.

Don't get me wrong. I liked the SB better. The 745 delivers 31.2 cfm @ 100 psi. As you said, it runs slower (730 rpm @ 100 psi for model 745) vs. 1035 rpm for the VR7F-80. The SB heads are CI & the Champion is aluminum. The Champion cylinders are aluminum with CI liner vs. CI on the SB. The SB is ~ 159# heavier. IR wouldn't give me any sound data. Champion claims 76 dB(A) @ 1m. SB claims 80.5 dB(A) @ 1m. They both have 1 year full warranty with the Champion having a prorated warranty after that up to 5 years.

What makes you think Quincy has some imported castings?

 

[benjamming]

That is what I was told when I called Quincy.

 

[malodin]

here is mine a thomas industries hp-1500 built in '93 60 gallon 125psi work horse, oh yah and its desinged to be in medical facilities and industrial applications(purchased it from a garage sale for $200) found out the head unit alone is worth 1700 new. Was quite surprised

though found out the cfm rating at 80psi is a dog at 4.75cfm(that just doesnt seem right and it doesnt ever run out on my impact socket)

 

[ww3]

Thought I'd do a first post in the compressor thread. This is a Curtis 80 gal 2 stage 17.4 cfm at 175psi. After using CH and Husky compressors, I decided I wanted a real machine and so far it has lived up to my expectations.

I looked thru about 1/2 of the posts and didn't see any, but . . .

Anyone ever heard anything about Eaton Compressors? They look to be one heck of a compressor, and when I update I think that's what I'm going to get unless anyone has had a bad experience w/ them

 

[G-force]

Don't know if I posted mine yet...

 

[Lhorn]

I wanna get a Quincy like that bad......some day. Can I ask where you found the best price and what model that is?

 

[benjamming]

G-force,
How much room do you have from the wall? What does Quincy recommend? Champion recommended 12" so I put it 18" away.

 

[G-force]

It's model#2V41C90VC

I got it for $899 delivered! My local farm store had a awesome sale of 25% off anything in the store.

Right now it's about 8" off the wall. I'll have to check the manual about proper clearance. It has not been up and running too much yet as I am still finishing up my copper pipe.

 

[torqueman2002]

Hi, newbie here.

How long can I get away with that?

I picked up a 2-year old Husky 2-stage 80 gal (Model: hs781003aj) from CL for $300 including flexible liquid tight conduit, wiring, and a disconnect.

It just needs some touch up paint on the back side; tried Rust-Oleum Regal Red, but way off.

Any one know where I can get touch up for this guy?

Did a lot of reading, particularly this thread, before buying a replacement for the 15 year old Craftsman that served me well, but couldn't manage the blaster I built last year.

Great forum.

sure. here is my 7.5hp Eaton. I would certainly recommend one for both the quality of the compressor and the support you get from the company. http://www.garagejournal.com/forum/showthread.php?p=494227&highlight=FFPL#post494227

 

[zackwatt]

Is Quincy better then Ingersoll Rand?

 

[G-force]

Is Quincy better then Ingersoll Rand?

I think so. Quincy is a step above most of it's competitors and their factory support is absolutely remarkable. Top shelf products and service.

 

[agoogol]

So here is mine - Kellogg American Model 201TV and 1 1/2HP....I have had it for a few years now, got it for Christmas from my brother in law who got it from a friend who.....

Really only used it sparingly so far, but will be more so in the future.

Anyway I do have questions - I don't know much about maintenance on these things. What am I supposed to do? Check the oil? Belt? Anything else? This is after an hour of cleaning and it is still filthy, any best methods for cleaning? What about the space between the motor and the tank, that has 1/2' of gunk in there...Wish I could paint it too.

Saw someone else posting about it, no I am thinking about putting it outside the garage to save some room, build a little shed thing for it and run the hose through the wall.

Any thoughts on this would be appreciated guys.

 

[Steve in Mi]

Drain the water from the tank after use! Stick and a rag might help cleaning between the motor mount and tank. That sure looks like a very heavy duty motor on it - probably last forever.

 

[RAYJAY]

take the compressor apart it should only be 4 bolts to remove the compressor head (complete unit ) and clean it really good if it greasy use mineral spirits and a APC then just paint it with enamel paint, install a new belt and your good to go just make sure you tape off any of the id plates for parts reference for a later date

Here is your sticky. Read up on thermal conductivity, it is simple physics no experiments necessary.

The greater the mass the worse the heat transfer. Copper is vastly more efficient at transferring heat than black pipe.

yes it that is the problem you don't want the pipe to heat up the longer the pipe stays cold the more water you pull from the system ,

please tell us why you want heat transfer ?? why do you want the piping to heat up ???? I want my piping to stay as cold as possible as long as possible............
