Don't use sand unless you want to develop silicosis.

I think I say wrong ... what I mean is 8 BARS !
We have had this discusion before: http://madmodder.net/index.php/topic,8079.msg86466.html#msg86466
But I'll still use the unit as shown here :loco:

Quite correct using sand you may develop silicosis and why its banned in industrial applications.
Works great once dried and cheap £2 a bag. It should perform totally different to the video. Give you some idea it must have took two minutes to do a spec of paint that with same gun can do in 5 seconds by altering the pickup.
Problem with those setups is the gun and pickup. Changed over to the BHP12 and pickup last year, now fire aluminium oxide 60/120grit at high speed a mass volume. 5 secs to do the bare metal area on back of cabinet.
I still get the constant blockages with the pickup so I now run as little grit in the cabinet as possible about 5 to 10secs worth of blasting before having to move media over pickup recirculation hole in bottom - modded.
Really need a bigger cabinet this year.
