Sandblaster Hose Size

admin

Hi all - I am trying to put together a sandblasting setup.  Harbor Fright cabinet,5hp, single stage, 60 gallon compressor.  I'll be using a pressure assist pot.I'd like to know the diameter of the hose feeding the gun?  I'd like to use a pedal to control the blast.  Any ideas?  Thanks!
Reply:HI You want at least a 1/4" inside diameter hose.  You need to look at all the components in the air path  As the smallest part will effect the air-flow. Increase the air pressure will help the volume coming out of the tip.  Static air pressure is not the same as air pressure when the gun is in use.Attached is a picture of the foot air controller I built (another guy's idea) that works great.But will the HF blast cabinet gun you will need to lock the trigger on when using a foot controller (hose clamp works fine). have funTom Attached Images
Reply:Thanks accourtjester.  Many thanks as well for the very cool pedal.  Never would have thought of building one with the link at the heel end of the pedal.

Reply:Its not a bad idea if he can clear the dust. Pressure pots are 5x faster than siphon feed units.
