Road Compressor Workings

[mr haynes]

Today i reacquainted myself with the out of sight out of mind old Ingersoll Rand compressor i picked up some time ago.

Question is what am i looking for regarding correct operation? Never had one before.

Fired first kick so at least the battery wasn't dead
Turned it back off after felt plenty air being produced.

My concern is the working of any blow off valves, which i assume there has to be.
What should i be checking?

Couple of pics

thats the same as mine.....
providing oils are OK they are fairly bomb proof.....
as for the unloading valve never seen one fail but guess they do....
mine has a hundred meters of hose so its kept away from me.....
I used mine for big sandblasting jobs...chassis and tractors.....
the road comp was connected to my workshop comp tank (around 400liters)....
that way there's plenty of over capacity and an extra blow of valve....

Think it had been serviced when i got it, oils and filter looked clean. Might look at connecting then to the 3ph compressor got stored next to it....
Really need to stop buying on a whim, storing, then forgetting details of what i've bought
Got around a tonne of media to get through, so any wheel, chassis, basically anything that doesn't move quick enough will be getting it!
Was looking at getting a new 15m long hose to connect to blast pot. Should really get a hood too...

it would be an idea unless you fancy choking and get red hot and peppered with grit

Used a shield and disposable mask when tried out blast pot on a wheel, the ground and myself....sometimes you just have to know....

Think the nozzle size is 3mm, will this be ok with the extra cfm?

Some pics of blast pot

if the comps about 70cfm change the jet to a 6.0mm one that blast hose looks to be half inch bore

Think it is either 85 or 100 cfm (when new). Can't remember which.

they tend t ake there air untill they make none, if the blow off valves are working right you know in seconds as if the pressure reg is adjuted way over they will blow off instantly nearly. my old clunker is still chugging on with much abuse but it passes a lot of oil as the seperator filter is done and there expensive for what i use it oil is cheep

the last road comp I had had a cylinder with 6 oil filter separators in and was sledged up I washed them in petrol and put them back in it worked a treat . until I plugged my air fed helmet in and the fumes made me pass out so I just fed that of my other smaller comp

Bit of an update:

Appears the blast hose is 3/4 id. Can i stick one of the chinese boron carbide nozzles up it or are they just for use with guns?



Since i will now be using claw couplings, should i get one that screws directly into water separator on the pot or use an adaptor between?

 

[brightspark]

I use claw coupling on the comp and the pot and have adaptors to fit hi flow couplings and pcl type

 

[brightspark]

just fit the blast jet in to the hose and hold it in with a jubilee clip if u haven't got the screw in type with holder
