Deadman Valve the only option for pressure blaster

[GarageGuy89]

I would like a gun style with a trigger. I find the ball valve or the dead man style valve cumbersome. Is there any way to make a gun style, similar to the siphon feed systems?

Also, I seem to be getting ALOT more dust and air volume coming out of the pressure system, compared to the siphon system. Is this normal? It is literally blowing out of the seams...where the siphon gun was not even close to comparison.

I have noticed that it cleans about 100 times faster. What took me 5-10 mins with the slow siphon feed only takes a few seconds with the pressure system.

Yes you are going to have more dust noise and air with a pressure blaster. I have never seen anything like what you describe that would be suitable for a pressure blaster

I believe your talking about home type dead man valves? The commercial type is just a open-closed pneumatic switch which has a valve that compresses the main hose from flow. If you put any type of gun or inline valve it won't survive long. Maybe something to cut the pressure off before the pot? Maybe a pneumatic foot switch?

This is a good idea, but I'm not sure how it would work. You have pressure going in at two locations, one at the top of the tank and one at the bottom to push the media through the line. So if you where to cut off pressure between the compressor and tank every time you turn the switch off you have 20 gallons of pressurized residual air left over, likewise when you go to turn it on you now have the compressor needing to fill up that 20 gallon media tank.

I like the idea but I don't see it working well for on/off blasting. Anyone try this?

My inexpensive pressure pot has a ball valve with a threaded adapter for ceramic tips.
