Sandblasters - gravity feed tank or pressure feed tank?

trick is dual regulaters.
low pressure on sand supply and higher on blast.
clean dry air.
and DO NOT use play sand!

Sorry I have to repopen this ten year old thread, because I have the same exact question.

This is my "new" sandblaster, it's gravity fed as you can tell. However, it looks to be very heavy duty not just used for small parts.

I'm reading through this thread that some would hate to sandblast an entire car with a gravity fed system. That is a pretty large hose, a lot of CFM. Worth restoring?

 

don't push th feed hose on all the way, there is a small hole at the bottom of the tank where the feed hose goes on, it is meant to let some air into the feed hose, so the air moves the sand

 

I've used an Eastwood that was similar. Worked fine as long as you had good media to use. You can sift play sand (you will have to, to keep it from clogging) or get some of the good stuff. I used the black stuff. (not sure the name as a local place told me I could scoop up all the broken bags worth I could use).

For what I needed it worked. If I had to blast all the time............I'd want something else.

 

that is not a gravity feed blaster. that is a pressure pot. you could easily do a lot of rust removal with that. restore it, it is worth it.

 

If you have a month of free time, by then you will quit the sandblasting. That compressor will run continuously and add moisture to the blaster, they are not meant to do what you are asking it to do. Look up the CFM on that compressor then what CFM you need to operate a pressure sandblaster.

Not everyone has the room or money for a huge compressor so they have to do what they can do.

 

The best blaster I use is a Tony B. I haul everything to him and usually the next day I get it back all clean and epoxy-primed..!!
I went thru the siphon/pressure pot hell for a while on the roadster project.. I don't have the patience ,time nor the proper equipment to do it...So ,in total ,I spend way less by paying to have it done....And no mess to clean up ,no sand to keep dry , no wear & tear on my compressor etc
Just my warped $0.02 worth

Amen!

Sift your media through porch screen will prevent clogging. I always find a some pieces in every bag big enough to stop the process. I learned this from one brand that was notorious for large debris in contents
I use a HF pressure pot with a 18 CFM compressor
