In all of the testing I’ve finished, there are solely two methods to hurry up blasting elements (assuming right media and strain for the job):
- Improve the quantity of CFM accessible.
- Improve the effectivity of your blast gun.
Let’s take a look at number one, CFM accessible. Including 5, 10, or 15 extra CFM will drastically improve blasting velocity, however at what value? That a lot CFM equates to purchasing a brand new compressor with wherever from 2 to five extra horsepower! Everyone knows how a lot compressors value…1000’s of {dollars} for a superb unit!
A neater option to clear up this drawback is simply to improve to a extra environment friendly blast gun, that method you possibly can hold your present compressor and spend much less cash to get the identical consequence.
If in case you have a blast gun that resembles the one pictured beneath, then I’m right here to inform you that the HTMR Blast Gun works practically 2x quicker given the identical air consumption. Even costly retail vapor blasters include weapons similiar as pictured beneath, so you possibly can improve your retail machine and make it RIP!
OK, so the “low-cost gun” pictured above could be very generally utilized in vapor blasting and it simply works…OK. This gun is definitely a DRY BLAST gun, that simply so occurs to work OK for vapor blasting.
There are solely 2 benefits to utilizing this gun:
- It prices $30-40.
- It has a boron carbide nozzle (lasts without end).
Oh boy there are a ton of disadvantages:
- It leaks. May be fastened, however leaks proper out of the field.
- Often ships with WRONG airjet/nozzle mixture.
- Not corrosion resistant, will start to rust internally.
- Cumbersome
- Scattered blast sample, can’t see blasting progress.
- No precision. Airjet and nozzle bores aren’t concentric.
- Takes twice as lengthy to blast elements in comparison with the HTMR gun.
- Nozzle design is just not optimum for environment friendly blast sample.
Under is an efficient instance of the poor high quality yow will discover whenever you purchase and use one among these weapons. The airjet and nozzle aren’t concentric, subsequently effectivity is drastically lowered.
So, for the previous few months, I’ve been engaged on a blast gun that solves many of the disadvantages listed on the “low-cost gun”.
Right here is why the HTMR Blast Gun is best:
- CNC machined within the USA. This presents very exact dimensions.
- Excessive circulation.
- Airjet and nozzle are concentric.
- Anodized aluminum physique for corrosion resistance.
- Able to dry and moist blasting.
- Gun may be arrange for quick “reducing” or “sharpening” velocity
- Normal media port thread.
- 1/2″ air hose
- 3/4″ media hose
- Tapered ceramic nozzle for higher viewing of blasting progress.
- Extra environment friendly blast sample.
Think about if you may get the job finished in HALF the time? What are you price per hour? What in the event you earn money vapor blasting elements and may get the job finished faster? Meaning you may be extra worthwhile. To not point out much less put on, tear, and power utilization in your compressor. Sure this gun prices extra, nevertheless it’s essential to take a look at the large image: a gun is a one time purchase, whereas time/power wasted can actually add up.
At the moment there are 4 sizes accessible to match 3, 5, 7.5, and 10HP compressors. You really want to take a look at the CFM spec @ 90psi and match a gun closest to that. For instance, my 5HP compressor spec is 19cfm @ 90psi. So the 5hp gun which consumes 16cfm @ 60psi is an efficient match.
Are you able to eat extra, or run an even bigger gun? Positive, I do it on a regular basis. Nevertheless, your pump received’t be capable of sustain and you’ll have to anticipate the tank to replenish. Not advocate except you blast small cussed elements for brief durations. You may all the time purchase totally different airjets and nozzles and simply swap them out.
- 3HP gun – consumes 10cfm @ 60psi
- 5HP gun – consumes 16cfm @ 60psi
- 7.5HP gun – consumes 25cfm @ 60psi
- 10HP gun – consumes 37cfm @ 60psi
Be certain to take a look at the DIY Vapor Blaster construct plans that I’ve. You may convert an present cupboard, construct one from WOOD, and even add options to a “base” mannequin retail machine.
