I'm rockin' the super-powerful HF 29 Gallon 5.3 SCFM (pun intended...) compressor. What would you guide me to purchase to make this puppy work? Thank you in advance, I've NEVER had luck with my blast cabinet so I'm hoping this will be the Unicorn! I'm going to presume the 1/4″ nozzle, 3/32″ Orifice noted on your website 'should' do the trick??
The 1/4″ nozzle, 3/32″ Orifice (12 CFM @80 PSI) will help if you've had a larger one, but 5.3 SCFM still isn't enough to keep it running continuously. The 29 Gallon tank will give you a run time between 6-10 minutes with the 3/32" Orifice. If you need to blast longer the answer is a bigger compressor. A 5HP compressor is what I would recommend.
I use an 18CFM gas engine compressor with a HF cabinet. I’ve also installed 1 inch tubing for siphoning/ metering. A couple days ago I was chugging along and blasted several parts, however I haven’t been able to find that sweet spot again. Now at most I get a small amount of media when I pulse the trigger. I can see media almost making its way to the top of the hose but it doesn’t have great suction after several hours of use. The HF gun is really bad too, the best performing ceramic nozzle was 1/8” and it wore out fast, I also had to keep the retaining nut loose and wiggle it around from time to time so a lot of media was falling out when the trigger was not pulled. If I’ve ensured there are no clogs and changed the media several times, would a gun like this give me more consistent performance? Also the metering valve doesn’t seem to have an effect on the suction.
There are a lot of factors in suction abrasive blasting performance. The gun paired with the proper nozzle and making sure the nozzle is not worn makes a big difference in the suction.

I am connecting two 6.5 hp compressors into one line that goes through a series of vertical pipe lines zig zagging. The line has a large air dryer at the end. What size orifice nozzle do you think I could have running the two 6.5 hp compressors together? Thank you
I have never combined compressors personally, but it can be done. If done properly it there should be very little loss of CFM. Your combination should yield around 40 CFM. Be careful. Also not sure what you're planning for, but a 6.5 HP compressor should produce around 22 CFM at 80 PSI, which would work well for a suction cabinet and 21 CFM air orifice. #4 gun on our website. This chart gives you CFM requirements for suction and pressure system. blast-it-all.com/cfm_requirements/
@@blastitall I plan to use the two compressors only if needed. I was going to use a 5/32 nozzle with a medium grit crushed glass. If I understand the use of the chart I should be good to go? Thank you for your help
If by tire air compressor you mean one of the little tire inflators, no. Most of the manuals I have read for those indicate the produces less than 1 CFM. The smallest CFM air jet we use needs 12 CFM. It is possible to get a smaller compressor, 4CFM, with a tank and blast for short periods of time. But for larger projects something the produces a few more CFM than the gun requires is what would be recommended. This shows how that works: ua-cam.com/video/TQoe0ov4M_c/v-deo.html
Just found your channel and Subscribed. Very interesting. Nice video

Can I use a car tire air compressor to power a sand blaster?

Just ordered a 59 cfm compressor
Nice! Which one did you get?
@@blastitall Polar Air 24 Hp Honda with a 60 Gallon tank
@@axisvaporhoningindustries4312 Very nice!👍
what size are the barb ends though?
The barbed fitting is 1/2"
