Turn off your Comco blaster at the wrong moment, and you may cause abrasive contamination.\u00a0<\/span>Don\u2019t worry, abrasive won\u2019t pollute your shop, but it will spread inside your blaster, infecting sensitive components.\u00a0<\/p>

We hate to be alarmists, but a customer\u2019s AccuFlo recently fell victim to abrasive contamination for this reason. Their production stopped for a week while our resident \u201cdoctors\u201d performed surgery. Here\u2019s the thing: this damage was easily preventable.\u00a0<\/p>

It may seem peculiar that a machine designed to move abrasive could suffer from such a malady. But, to understand why abrasive contamination happens, you must understand the machine\u2019s design.\u00a0Let\u2019s look at where abrasive is allowed to flow inside your Comco blaster.\u00a0<\/span>Then, we\u2019ll\u00a0look at where abrasive should\u00a0not<\/em>\u00a0go, and how you can keep your blaster healthy and happy for years to come.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

Two Sides to Every Blaster<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Your Comco micro-abrasive blaster has two sides: a \u201cclean air side\u2019 and a \u201cdirty air side\u201d. Anything sensitive to abrasive contamination sits pristinely on the \u201cclean air side\u201d of the blaster. For example, the regulator that monitors air pressure and the controls that manage the PowderGate or pinch valve live on the clean side.\u00a0<\/p>

The \u201cdirty air side\u201d is designed to withstand the erosive effect of abrasive. The components on the dirty side are either built to traffic abrasive or accommodate occasional fugitive particles. The abrasive tank, the mixing chamber, the abrasive hose, and the nozzle comprise most of the \u201cdirty air side\u201d.<\/p>

You know how beach sand seems to sneak into well,\u00a0every<\/em>thing<\/em>? Well, micro-abrasives are finer than beach sand, and thus, more likely to sneak into tight crevices. Micro-abrasives can be as fine as moondust and as hard as diamonds\u2014a killer combo for sensitive machine components.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

The flow-path for abrasive in a Comco blaster is hard-plumbed, and 99.9% of abrasive particles move in one direction from the tank to the nozzle.<\/span> We do not anticipate abrasive reaching the modulator; however, in order for it to work properly, it has to have a direct and open connection to the tank and mixing chamber. Therefore, the modulator and the path from the modulator to the tank are designed to withstand the occasional stray particle. <\/p>\n

The dirty air side and the clean air side are well-protected from one another. General physical barriers\u2014including a check valve and a filter\u2014provide sufficient blockades as long as air pressure remains balanced.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

In the mid-2000s, we reduced the opportunity for operator error by integrating the tank depressurization control into our blaster\u2019s power switch. Since then, turning the power control to off automatically vents our blasters.\u00a0<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Even with this design change, operators still have to make sure that the house air pressure or the pressure in the supply air line is higher than the abrasive tank\u2019s pressure. The abrasive tank pressure is also referred to as \u2018the blast pressure\u2019 which is indicated on the regulator.\u00a0In any Comco blaster, a\u00a0low-pressure region forms when the house air pressure drops below the air pressure in the blaster\u2019s abrasive tank.\u00a0<\/span>This imbalance pulls abrasive en masse backward from the tank and through design barriers.\u00a0Like most machine components, the check valve and the seal have limits and getting pummeled by a lot of harsh abrasive is one.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

    If your blaster falls victim to abrasive contamination, it will cease to function well. Here are some tell-tale symptoms:<\/span><\/span><\/p>

    Abrasive appears in the regulator, the valve assembly or pinch cylinders.<\/span><\/span><\/p>

    The pinch cylinder ceases to respond to the foot switch. (The pinch cylinder or PowderGate does not activate when the footswitch is pressed. The pinch\/Powdergate does not close properly when the footswitch is released.)<\/span><\/span><\/p>

    The pressure refuses to adjust.\u00a0<\/span><\/span>The inlet valve bleeds air.<\/span><\/span><\/p>

    The unit pictured here sat powered on over a weekend while the facility\u2019s air compressor was turned off. The resulting pressure imbalance sent abrasive backward through the blaster, clogging and damaging essential components on the \u201cclean air side\u201d.\u00a0<\/i><\/span><\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

    Prevention is worth a pound of cure, or in this case, worth a week or two of downtime for repair. You can avoid creating a pressure imbalance by:<\/p>

    Turning the blaster on last and off first.\u00a0
    <\/b><\/span>Disconnecting the airline or turning the compressor off ONLY when the blaster is off.
    <\/span>Verifying the compressor is on BEFORE turning the blaster on.<\/span>
    <\/span>Keeping a 10 psi buffer between house\u00a0pressure and blast pressure.\u00a0<\/span>For example: if the low point on your house pressure is 90 psi, then do not blast higher than 80 psi.
