Hose length / pressure loss help please!

[Jackimus]

p.s. do you have the cleaning tool already? can you test it on your compressor and turn the valve on the compressor up/down to see how much difference it makes?

there's a chance lower flow (to a point) makes naff all difference

I've managed to figure out that it works between 90 and 65PSI, so whacking the compressor on 90 and ending up with a number somewhere in that range should be fine.

10mm hose gives a drop of 7.5PSI, 12mm 3PSI and 15mm 1 PSI. So I reckon for this particular tool 10 would be fine, but I'll probably go for 12 or 15 to cover whatever else might be on the end of it, depending on if there's a meaningful cost difference at 50m / maybe getting a 100m roll and chopping it up...

What I do is have some longer larger bore hoses and some shorter 3/8" ones which I just use on the end of the tool or for the last few meters, all with XF fittings.
That way you still have something fairly manoeuvrable but you are minimising the length of hose restriction.

Right now I've got four metres of 10mm ID hose with XFs for the workshop, I was already seeing pretty significant drop from a turbo air gun, but that is hungry, I think 18CFM at 90PSI. Also the same for an older cut-off tool that I couldn't find numbers for.

50m would be the amount needed to get it across my flat, out of my second floor window and down to the kerb... And that seems like the easiest way to do it lol

50m of air hose will be a nightmare to put away.

Whatever tool you need to run that far away from a compressor just buy in cordless!

I will admit I'm in a bit of a sunk cost fallacy with the compressor, trying to make as much use of it as possible since I have it... But there doesn't seem to be a cordless answer to the Tornador, in the same way that air is king for paint spraying (unless you spend big bucks on airless?)

Last time I refitted the workshop air system - I went for reels of 16mm nylon pneumatic tube. This got an inside diameter of 12mm

I did thou pipe it up as a "ring main" - this really does make a difference. All fittings and valves/regulators were 1/2" (which gives a bore to match the tubing).

Real big air guns 3/4" & 1" - I use off an filter/oiler direct off the tank with an 1/2" ID hose with PCL 100 series fittings.

Pretty much exactly what I did for my DIY garage. Able to supply it with a small compressor in the garage, or the hydrovane under the house via some even bigger bore nylon tubing that was a right tw at to push/drag through the conduit under the patio from inside the house into the garage, through a PCL dropout. Short hoses to tools if needed.

And a big bore PVC hose direct from a connection near the hydrovane to the blasting cabinet in the shed.

cordless tools have their place and uses.
