Air Compressor

[Bsmith]

I built it about 8 years ago, used and works well.
Tank is a large size propane cylinder so around 100ltrs.
240 volt single phase.
3 horse power motor.
Auto start / stop.
Runs off a 13a plug.
Wheels on one end, handle on the other.
Tank outlets are pcl female + 1/2 bsp ball valve and condensate drain valve.

3hp? I'm sure mine has the original 1hp motor.

must have only had a 3hp spare well it wont overheat

I really didn't know what hp that pump would need to drive it, i bought the pump on its own from a fella who didn't know what it came off, I thought mighta been on a lorry airbrakes or something. I would have expected it would take a bit more power than 1hp when the discharge press came up to 80 -100psi.
Do you know what rpm your pump runs at? If I am keeping it I could maybe change one of the pulleys to make it run faster.

 

[Seadog]

Mine has an operating pressure or 10 nar, 150psi. I think that it's rated to run at 900rpm. This is my rebuild thread

Ingersoll Rand compressor resurrection

I picked this up on FB Marketplace for a song last year. It had been advertised over s period of months for £40 and then I happened to see that it was down to £20, and local. Too good an opportunity to miss. As you can see, it's 3-phase hence why no-one was interested. The first job was to...

i wouldnt make it run faster find out the correct speed

 

[Bsmith]

Right, interesting. Dont know where I was when you posted that one but I didn't see it. I never had this pump apart.

I havn't a clue what speed mine runs at, will check soon. I pulley'd it so it looked to run and sound like compressor speed.

Since plenty of power from 3hp I could increase the rpm if it is lower than 900rpm which @Seadog thinks is the designed rpm.

 

[not done it yet]

About 3-4cfm FAD at rated speed? Enough to run most air tools, as long as not needed continuously. Most air tools seem to claim 4cfm @ 6Bar - but they often actually need more as they are used… andspecs are always the best attainable.

 

[Bsmith]

Checked today and it is running about 1300rpm. Tried to transfer video from phone to here but having difficulty.

 

[Bsmith]

Would mods please move this to compressor and air tools section?

No longer for sale, change of plan.

 

[not done it yet]

Still a better compressor than most of the modern-day rubbish that adorns the shelves of the ‘stack ‘em high, sell ‘em cheap’ outlets.

I’ll not change my twin compound CI pump for a high revving alloy thing, even though the new ones are possibly more efficient. Cast iron rules, for longevity.

 

[Bsmith]

Compressor now running at 900rpm with 1.1kw motor.
Think I'll keep it a while yet.
This is actually a video of it running, wonder why it shows as still pic?

 

[Seadog]

You need to upload the video to, for example, YouTube, then post the shareable link.

Nice job on the belt guard. I see lots of old compressors on FB / eBay where people don't bother.

 

[Erie Fred]

Tank needs some horizontal pinstriping....makes it look "faster".....
