Psi for blasting pressure pot?

[julianf]

I've done a bit on Google but still can't be sure -

Psi to set the regulator to for one of those cheap pressurised blast pots?

I know CFM is required to maintain, and that's fine, I have a couple of compressors, but I just can't find the pressure setting to actually charge the pot to?

Can anyone please advise?

Thank you.

I've run mine at 50psi in the past, that way the compressor can keep up with the air requirement or my wolf dakota 3hp compressor. you can run it at 90psi, but the pressure will then drop and you need to wait to get upto 90psi. at the lower pressure it will run all day, and may take slightly longer but you're not waiting about. the size of the nozzle you use will also change the air requirement too, a bigger nozzle needs more air

Does the pot have a max pressure stamped on the side? Id guess its somewhere 65-100psi, but havent used one.

90 psi for optimum blasting mine is at about 90 min up to 125 psi i dont bother regulating it just use tank pressure
