This video gives you a good explanation of how much to put in and where. ua-cam.com/video/zTm1bg5uTPQ/v-deo.html

Good Morning A 25 Horsepower compressor should give you about 87 CFM at 80 PSI. If it is all dedicated to blasting you could go up to a #8 gun which would have a 1/4" Air Jet and 1/2" Nozzle. I would recommend you stay under sized at a #6 or #7. You can find a CFM chart here: blast-it-all.com/cfm_requirements/

After blasting with several different types of media including plastic, I can say I have never had media behind the mylar. However, it does seem to attract dust from the media, but not behind. If you are using our mylar dispenser, the dust collector needs to be turned off before loosening the nets and advancing the mylar. If it is left on it will pull the mylar in and allow media and dust to get behind the mylar.

@@blastitall Thank You

At Blast-It-All we make and support abrasive blasting products. The crew in the video was putting in power for our new building. I am thankful for the service our linemen.

Some things we blast throw more media back at the glass than others and most media can frost the glass fairly quickly. ua-cam.com/video/EnhMx1E3LMA/v-deo.html But the protective film has a tendency to statically attract dust. I sometimes wipe the film before starting to blast. The best way to help with this is make sure the dust collector and air flow through the cabinet are working properly. ua-cam.com/video/rHTO5KMZk5Q/v-deo.html

This one was done @ 80 PSI.

Fantastic. How many horse power is it?

@@blastitall 175psi 30 gallon 2 horsepower oil / belt dewalt compressor, it’s technically not rated high enough scfm at 6 /90psi and blasting requires 10 /90psi but i found that i didn’t lose pressure and was able to soda blast an entire cylinder head without stopping in about an hour

@@nothxgs What pressure are you blasting at? Was your compressor running the whole time?

@@blastitall i used walnut at 130 psi and switched to baking soda at about 90 it wouldn’t flow with the higher psi but it would only run constantly if i held the sprayer down, i burst it instead to try and save material

@@nothxgs 130 is a little high for suction blasting, it changes how the venturi works to pick up the media. Most people blast at 60-80 PSI. Busting makes sense. If the it was running constantly the tank would eventually drain and suction would stop. What gun do you have? Most guns the guns I have check that say they are 7 CFM are not. ua-cam.com/video/tfRZ-5cdlY4/v-deo.html

We offer standard nozzles, wide spray nozzles, and nozzle extensions. Wide spray helps spread out the blast, as you might think. The nozzle extension is nice when you are trying to blast down into something. Hopefully will have a video on the nozzle extension soon.

For suction cabinets the answer is always no. This is a good guide for that: ua-cam.com/video/zTm1bg5uTPQ/v-deo.html For pressure cabinets you would want to put in enough to almost fill the entire pressure pot. This can very greatly as pressure pots come a wide range of sizes sizes.

I have lots of videos I can't show you because of NDAs. Mainly larger commercial customers.

Our reclaims feed the gun, so the media is continually air washed and you can keep blasting.

Agreed, this was blasting for the sake of blasting. If you are going to blast to re-season and use the pan it needs to be aluminum oxide. Aluminum oxide leaves the cast iron in the proper condition to be re-seasoned. ua-cam.com/video/_Mwr8kdlZ1I/v-deo.html

@@blastitall I make spatulas from new Lodge seconds but I wouldn't consider using a vintage piece unless it's cracked or otherwise destroyed as an historical piece. I do enjoy taking something considered worthless and making it a prized piece.

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

@@jimdrechsel3611 5/15" Nozzle and 5/32" Air Jet

This cabinet was designed to be used with lighter weight media (Aluminum Oxide, Glass Beads, Crushed Glass, etc). We also make cabinets designed for steel shot and cabinets designed for soda.

I am certain abrasive blasting could remove the coating on the other non stick pans, however the processes described online to re-coat them seem unsafe for cooking. However, reasoning cast iron cookware is as safe as it always has been.

We have a larger compressor, because we run the whole shop with it. The air jet and nozzle combo in the gun for this video requires 21 CFM at 80 PSI during blasting.

@@blastitall thank you

The barbed fitting is 1/2"

That was blasted using our ECO suction trigger gun. The Air Orifice on the gun in the video was 3/32 and the Nozzle was 1/4". I have done other videos with larger nozzles and air orifices. I usually use a number 4 gun. This sizing chart gives you the correct orifice and nozzle pairing: blast-it-all.com/cfm_requirements/

There are a lot of variables, but for our cabinets with a 300 CFM dust collector we usually have a 2 x 4 oval hole for inlet. Essentially a 3" hole.

The harbor freight gun is not what it is advertised as. ua-cam.com/video/tfRZ-5cdlY4/v-deo.html

If you need a trigger operated gun our 12 CFM would be a good fit. blast-it-all.com/product/gun-eco-w-14-ceramic-nozzle/ If you use a foot pedal controlled gun then our 12 CFM would be a good fit. blast-it-all.com/product/3-gun-complete-w-ceramic-nozzle-1-4-diameter/ This CFM chart shows you how the nozzles and air jets are paired and the required CFM: blast-it-all.com/cfm_requirements/

If you stick to a suction gun that is 21 CFM or less. That would be our number 4 gun with a 1/8" air jet and 1/4" Nozzle. This chart shows how they are paired: blast-it-all.com/cfm_requirements/

@@blastitall thanks for the info I appreciate it 👍

That's what I use

Why??

Yes. Steel shot is much more dense than aluminum oxide which makes recovery more challenging. But the biggest issue is the explosive hazard that is created when blasting with the two.

@blastitall what do you mean by an explosive hazard? I've mixed them together unknowingly. I have a metering valve. The biggest issue it seems is my flow is not good and it's clogging.

@@BimmerFix The flow issue is most likely related to the density and weight. Steel Shot 300lbs per cubic foot Aluminum Oxide 240lbs per cubic foot When you say "mixing" if you mean using them at the same time, that is a bad idea. If by mixing you mean switching back and forth, you need to make sure everything is cleaned out when switching. This is from the SDS for steel shot Particles liable to produce a fire hazard are the following: •Metal dust. •Plastic dust. •Dust produced when blasting metals coated with paint, rubber, etc... The SDS can be found here: blast-it-all.com/wp-content/uploads/2024/05/SS-SDS.pdf

@blastitall thank you for your reply. In this case, any blasting is a fire hazard, it seems. I guess the mistake I made, I dumped 50lbs of AlOx and 50 lbs of steelshot together in the blast cabinet. Then I realized that's too much, so took most of it out. Still can't blast with good flow...BTW bag of 50lbs steelshot was 5 times smaller than 50lbs bag of AlOx. Should I just throw it out now? I figure there's no way to separate them now...

Yes and no to fire hazard. Aluminum oxide, glass bead, and crushed glass are not listed as fire or explosion hazards. However, organic media, steel shot, and some others are. As for the mixture. I don't think there is a good way to unmix that.

The CFM requirement is based on the nozzle size and the PSI setting. A 3/16" nozzle at 90 PSI would require 41 CFM. On the right hand side of the page below there is a CFM requirement chart for pressure which is what this machine it. blast-it-all.com/cfm_requirements/

Beautiful machine

Siri what size compressor do I need to run my DEWALT Abrasive BlastVac for Clean, Portable Sandblasting?

Blast and wait isn't necessarily a bad. It all depends on the project. One of the big issues is the incorrect labeling of blast guns and the CFM needed for blasting. This causes people to have to blast and wait when they were not anticipating it. This video explains one of the issues with a very common gun: ua-cam.com/video/tfRZ-5cdlY4/v-deo.html

May I ask what compressor that is?

@@ShockeyUSA the one in the video is a MCGRAW 21 Gallon, 175 PSI Oil-Free Vertical Air Compressor from Harbor Freight. It is my personal compressor. I purchased it about 4 years ago.

The principals of suction will still work outside the cabinet. Provided you have the correct compressor for the nozzle and jet pairing. Moisture is your enemy. Try to keep the media dry.

If the cabinet is from Blast-It-All, yes it can be added. If not , it will depend on the cabinet. What kind of cabinet do you have?

?

If you are close by we would love to let you see it in person. We are also looking for way to improve. Do you have any suggestions?

Fantastic

What type of work were you using the compressor for?
