Air Line Bore

[langy]

I've run PCL for years and they have worked great but recently got given a load of the Euro fittings so put them on my main compressor and the difference I found is fantastic, I will definitely be changing my other compressor over very soon

Not just air guns which are run off them.

I realise that. I have loads of air tools, impact gun, orbital sanders, polishers, wrench, drills etc and not having any problem. Just curious as to what tools do have problems so I can avoid or adjust accordingly.

I would suggest adding a second receiver to give more storage capacity and some form of quick disconnect pipe if you move your compressor around, many options exist and you may have to periodically stop to prevent overloading the compressor, but your tools will all work correctly.

Not having any problems and having full performance isn't always the same thing, it may be that an 8mm hose is doing enough for your needs but it doesn't mean to say everything is able to deliver its full potential.
Also there are many, many other variables such as: hose length, number of and type of couplers/fittings, system pressure, regulator/filter/oiler flow rates. If everything else is in your favor you may get away with a smaller hose, whereas a bigger hose may be much more important if other parts of the system are restrictive.

do you have a link to the ones you're talking about ?

 

[james butler]

machine mart sell them but theyre not on the website and they are quite expensive

I was given them but I believe they came from ebay originally
I just had to get some more so bought these and they are indentical and a bargain at £7.50 !!!

I agree bill, I ran 12mm hose to 15mm Copper all around my shop and have drop downs every 8ft so my airline is only about 10ft long and 10mm bore, made a huge difference to how the tools work

I use a single 8mm hose straight from the air bank regulator which is direct from the filters and air dryer. One of the coiled types. I have a 12mm hose as well and it makes no difference to my tools but is a pain in the ass to use as its so bulky.

most.tools u probably wont notice there slightly down on power using small couplings and hoses but upgrade them both including a decent half inch bsp filter regulator and u soon will and by the way there's loss on coiled hoses there only any use for blowing up tires and blow guns its not loss of psi its loss of cfm flow

Well whatever works for you, but generally speaking in most circumstances you would expect to find a difference in power as less air flow is available through both smaller and coil lines.

That's about the size of it. I've been looking for a discarded lorry coiled air brake hose just to see if it's a handful to use or not. If I pick one up for nothing (and they get replaced on a time basis, I think) it's no loss if it's no good to me.

Makes interesting reading.

Pressure drop in compressed air pipes and fittings is not just about diameter but length as well, along with pipe roughness, number of bends etc etc. try this simple calculator, it might answer a few questions and help with workshop design.

It does not go as small as my compressor and pipe!
