looking for some advise on sandblasting, i have a pressurised 20 gallon blaster with a 150ltr 3hp compressor, i am using fine crushed glass, problem is when i first fill it the glass come out without a lot of pressure but when the tank is nearly empty it works well but not for long as there is not much media,working pressure for it is 60- 100 psi and it seems ok, any suggestions?

Job to diagnose from a distance, but sounds to me, that the valve controlling the media is too open, and/or the valve controlling the blast air is too closed.
Suggest start with media valve completely closed, set up your air flow, then gradually open the media valve until you get the results you require.
A guide is, less grit more air gives a vicious clean, more grit less air gives a gentle clean

Thanks, that was the problem, the manual said to open the grit valve but its much better only 1/4 open
