are u talking safety blow off valve here its there for a reason and shouldn't be exceeded. the pump will only be designed to run at 100 psi maxI'd just swap it for a higher pressure one then

the tank has a saftey plate ratted to 8bar?
the blow of valve would be the easiest and cheapest option to change once up to 100psi the belt driven will fill the last bit
I am getting confused is it the 8 Bar (116 psi) safety valve you want to change/uprate?
If the tank is tagged at 8 bar I wouldn't want to be around it at 150 psi for any amount of time, some of the modern tanks are around 3mm thick in places, before they rust internally. a old tank from say pre 1970 uk built will probably be around 8 to 10mm typically from what i have seen.
All I want to do is safely run the 2 compressors linked together to give me more air.
Ok i have just read this from post 1 , you have a few options:-
1, Fit a regulator to the bigger compressor set to 95psi when you are spraying and link the two as in you existing set up. - only once you are using air will you find out how they work you will probably find the smaller compressor is running more as at the beginning the big one won't see any demand until the small one drops below the cut in pressure on the big one.(when not spraying you can either turn reg up or remove)
2,Fit a non return valve on the smaller compressor and link to the bigger one. - your bigger compressor will do most of the work but if if runs out of puff and drops below the cut in point on the small one (probably around 80 psi) then it will cut in to help with the demand.( you might want to put a t and valve in so if you just want a little air for a blow gun you don't need to wait for the big tank to fill to 100psi)
3,Reduce the cut in/out pressure on the bigger compressor down to match the small one. ( this is ok if you don't want high pressure for a impact gun)
4, Set up as in 1 above but control the 2 pumps with a plc to share the duty to either one pumps till tanks full then next time air is required the other one starts, or pump 1 will run for a fixed period the pump 2 runs for a fixed period then back to 1 and so no.(this will help with cooling old plc and contactors can sometime be picked up used for a reasonable price)
All depends how you see yourself using most of your air, i would go for 1 or 2.
Both ideally need valves fitted so if you just want a little air or are in a hurry you don't need to wait for the both tanks to fill.
Also should you have a failure while spraying if easy to carry on with the good one till you're finished.
Just one more note you mention a air fed mask is the compressor in a different building or fed with ducted air from the area outside of where you are painting.
Think i have got it all covered now BUT if the tank is stamped 8 bar do not run it at 150 psi.
Any questions just ask, hope that all makes sense( not having a good day with the painkillers today)

Whats up with the pain killers not working or bad side effects?
