The Dustless Blaster works by mixing water and abrasive inside the blast tank. By introducing water we’re drastically increasing mass and energy the machine is putting out, while eliminating dust. Imagine throwing a handful of dry sand, versus throwing a handful of wet sand; which one is going to have a more significant impact on the target? Not only will the wet sand hit the target harder, but it won’t disintegrate and become a cloud of dust like the dry sand will. This is the very simple principle behind Dustless Blasting. The Dustless Blasting system has the following advantages over the old, outdated dry blasting method:
Faster The Dustless Blaster can strip a car in under 2 hours.
Minimal Dust The abrasive gets trapped in water and grounded, eliminating the plume of dust.
Lower Abrasive Consuption The Dustless Blaster uses less media to do more work.
Abrasive Flexibility The Dustless Blaster can use almost any abrasive that sinks in water.
No Warping The water prevents friction and won’t warp thin metal like sandblasting will.
Safe for Workers Recycled bottle glass contains no free silica, the leading cause of silicosis.
Less Containment Needed In most cases, expensive, time consuming containment doesn’t need to be set up.
Doesn’t Affect Nearby Workers Never sacrifice productivity, other workers can work nearby unaffected.
Leaves a Paint Ready Surface The rust inhibitor decontaminates the metal leaving a clean, chloride free paint ready surface.
The Dustless Blaster can use just about any abrasive that sinks in water and doesn’t dissolve. Our favorite is recycled bottle glass because it’s clean, cheap, good for a wide range of jobs and eco-friendly. If you choose to use another blast media you need to make sure it has minimal trash and a consistent particle size. Lots of trash or dirt will turn into mud inside the machine. Watch the video below for tips on choosing an optimal media.
The Dustless Blaster is a high volume air tool that requires a large compressor to be effective. These large compressors usually measure their air volume output in Cubic Feet per Minute (CFM). Below we have a chart that indicates what size compressor you will need to run various DB machines.

We use a rust inhibitor to prevent flash rusting for up to 72 hours. This extremely effective rust inhibitor is added to the blast water to prevent flash rust during blasting, and then used to rinse after blasting is complete. Watch the video below to learn more about rust inhibitor and how to use it correctly.
All of our machines are capable of the same process. The main difference is size, so what blaster you choose is only a matter of convenience. If you don’t mind having to stop and refill 4 times while blasting a car, the DB225 is perfect for you. If you want to refill less, get one of the bigger models. The approximate blast times are listed below:

It varies depending on nozzle size and abrasive flow. To strip a car in 2 hours it should take about 4-6 bags of glass. To strip a car in 1 hour (like in the Impala video) it may take 8-10 bags. The higher the productivity the higher the media flow.
The abrasive will settle on the ground beneath or very near to whatever you’re blasting. If you’re in a place where you need to dispose of this media, the easiest way is to spread out some plastic before you begin blasting, and roll it up after blasting. Watch the video below for tips on the easiest way to blast a car.
Warping occurs when the metal heats up due to friction from dry abrasive. The Dustless Blaster will not cause warping, because friction and heat are reduced by the water. In fact the temperature of the metal being blasted usually comes down about 10 degrees from ambient. Some people say warping can still occur regardless of temperature, we disagree. Have you ever seen a blacksmith working cold metal? With that being said, you can still bend metal by applying too much pressure, just like you could bend it with a solid object. For large flat pieces of metal like trunks or hoods we recommend using about 70 PSI at a 20º angle to avoid bending metal. Also, be careful not to separate the sheet metal from the metal bracing on the underside of a trunk or hood.
Glass and chrome can be damaged by any kind of abrasive blasting. You should always mask off the chrome and glass prior to blasting. Watch the video below to see how to prepare a car for blasting.

Choosing the right nozzle for optimal productivity
Choosing the right nozzle is the key to achieving maximum productivity with whatever air compressor you have available to you. Choose a nozzle with too small of a bore and you’ll be leaving some blasting capacity on the table. Choose a nozzle with too big of a bore and you’ll lack the pressure to blast productively. There’s a balance to be struck, and it starts with your air compressor.
The more air volume you can compress per minute, the higher the pressure produced at the nozzle. This improves your production rate in two ways:
-
High pressure increases the velocity of the abrasive particles, delivering more kinetic energy upon impact, imparting a deeper anchor pattern. This allows you to use a finer grade of abrasive, which produces more impacts per volume.
-
More air capacity lets you use a bigger bore nozzle, which allows you to put more abrasive on target.
Assuming that the air compressor capacity available to you is not unlimited, you’ll need to select a nozzle with an orifice small enough to maintain a productive air pressure at whatever volume your compressor can supply.
NOZZLE SIZE
For vapor abrasive blasting, the most commonly-used nozzle orifice sizes ranges from 3/8” inner diameter to 3/4”, increasing by increments of 1/16”. A 3/8” nozzle is sufficiently constricted to produce a effective blast pressure with a 185 CFM compressor. A ½” nozzle is sufficient to produce an effective blast pressure with a 375 CFM compressor.
It’s important to note that when you double the diameter of the orifice, you quadruple the size of the orifice and the volume of air and abrasive that can pass through the nozzle. To find your optimally productive nozzle, determine what nozzle pressure (PSI) you need to maintain for productive blasting, and what volume of air your available compressor can supply per minute (CFM), then consult the following chart to find the nozzle orifice size that meets those parameters.

Bear in mind that your compressor will produce less pressure at the nozzle than what is indicated on the chart, depending on the condition and configuration of your equipment.
Nozzles wear out. Abrasive passing through the nozzle will wear away the lining, enlarging the orifice. A worn nozzle requires more volume per minute to maintain your target pressure. For example, If you bought a #8 (1/2″) nozzle to get 100 PSI with your 375 CFM compressor, once it has worn out 1/8″ diameter to the next nozzle size up (#9 – 5/8″), you’d be lucky to maintain 65 PSI using the same compressor (on the #9 line, the 375 CFM compressor falls between 350 and 400 CFM, so you can only maintain 65 PSI), because the volume of air passing through the enlarged orifice would be inadequate to maintain the pressure.
However, if you purchased a #7 (7/16″), still using a 375 compressor and targeting 100 PSI, once it had worn out to the next size up (#8 – 1/2″), you’d still be able to achieve 100 PSI, but you’d sacrifice some productivity earlier in the nozzle’s life (compared to a #8 (1/2″) nozzle) because the amount of air and abrasive that could pass through the orifice at 100 PSI would be less than what your compressor could supply.
Pressure can drop significantly between the compressor and the nozzle, up to one PSI per 50’ of hose (1” I.D.). In addition, pressure will drop with each bend in the hose or change of direction: the shortest, straightest hose configuration is best. On top of that, if there are ill-fitting couplings or leaks in the hose, the pressure drop could be total.
Not only does the size of the nozzle bore effect volume and pressure, but it effects the size of the blast pattern. For each nozzle size increase, expect up to a 10% increase in the size of your blast pattern. But it’s the shape of the nozzle, rather than orifice size, that has the most impact on the size of your blast pattern.
