At least you now know how much your compressor is putting out.Ok I've just timed the thing from empty to cut off at 8 bar / 120 PSI.
It took 11.5 minutes.
That's slower than the one linked to earlier in this thread.
Is it hissing excessively from the unloader valve before it goes quiet?Ok I've just timed the thing from empty to cut off at 8 bar / 120 PSI.

No it's fine.Is it hissing excessively from the unloader valve before it goes quiet?
Mmm interesting,There is something seriously wrong with your pump then! Have you owned this compressor from new or did you buy it used?
It should fill from empty in about 3 minutes in my opinion going by my own compressors. (One 200L 3hp SIP and a Tandem combined 6hp ABAC 300L)
The head Reed valves can fail or the head gasket can blow like what was the case on my used ABAC compressor I bought. One pump was doing all the work the other one was dead but "pumping" away.

Head off time then.No it's fine.
I've had a quick look online but can't find any spares for this thing, SIP say parts are not available.
I don't want to rip it apart before I can get spares.
A4 Sheets of gasket material are on Amazon.
If it's like Joepro's you can't make it any worse. Just be gentle with it.
Those plastic screens dont last long in them blasting cabinets. Replacing mine with solid glass and doing a mod so it can be easily replaced in the future.Some progress
I checked the drive belt and found it a bit loose so tightening that up, the air filter was clear and the compressor inlet looks new, I also drilled a couple of extra holes in the filter cover as it looks very restrictive.
It still took 11.5 minutes to fill so no improvement there.

I found the regulator on the compressor wasn't turned up very high
So with that set at 85psi.

I then checked the pressure on the pot and it's the same.
The pot was only reading 30psi before

I then lashed up the pot with a hose and flattened an air fitting into a kind of nozzle, put it in an old dustbin and tried it.

Feck me it kicks up some dust now!!!
It cleaned half this bin up in a few seconds rather than a few minutes to do a couple of square inches before.

Not perfect but the nozzle wasn't great
This was using some very fine glass bead.
So maybe the compressor does need looking at but for now it's good enough to do the job.
As for the cabinet, I can now see I'll need some extraction, new gloves, better lighting and viewing screens!
Thanks for all the ideas and tips folks
thats all i use just glass it lasts ages you can see what your doing and quick to replace when i doThose plastic screens dont last long in them blasting cabinets. Replacing mine with solid glass and doing a mod so it can be easily replaced in the future.
I'm sure when I looked into this some years ago the pumps were made by ABAC, not SIP themselves - and ABAC have (or did have) a searchable parts catalogue on their website. You do of course first need to identify your pump from the myriad on offer...I've had a quick look online but can't find any spares for this thing, SIP say parts are not available.

I went the other way: after replacing the glass a couple of times I switched to a sheet of 10mm Perspex but wrapped it in 2 layers of clingfilm. Eventually the film gets tatty but you can just rip it off and replace in seconds (only two knobs hold the glass in place on the Guyson).Those plastic screens dont last long in them blasting cabinets.
