Do you have any problems with it not feeding, I think that's the same one I have been using in the back of my friends shop. He's got 2 150 gal tanks hooked to it, so I don't think there is an issue with the air. When it works right I could do a manifold in probably 20 min, when it isn't it can take hours.

 

commando, At times yes I do, what happens is if you dont have a dryer on your comp. the moisture gets into the nozzle, then causes the sand to harden, you have to take the blast nipple out and use a pick to get the hard chunks of sand out of the barrel then it works great again. and too if you dont sift the sand very often , you get all the chunks of goo from the parts in the sand intake and it plugs it up. If you start loosing pressure just hold the end of the gun against your gloved hand and tap the trigger a couple times, this will force the air backwards into the intake tube and clear it out.

 

I never pulled the nozzle off, that might be a good starting point, I do however have it unclamped into the gun so I can blow out the feed line every so often. Thanks.

 

Glad to be of help your welcome.
