An Engineering Breakthrough

The AccuFlo® is the most powerful, precise, and efficient blaster in our MicroBlaster® line. It is such a design breakthrough that we had to give it a new name and its own page.

This improvement on our classic MicroBlaster incorporates the advanced features of our robust units, like the PowerFlo®, and exceeds the reliability and performance of its predecessors.

The AccuFlo suits most applications and is in use across industries—from small independent labs to major manufacturers. It easily transitions from use in single-operator processes to fully automated production environments.

Comco AccuFlo abrasive blaster

Designing the AccuFlo®

Abrasive blasting naturally creates harsh environments.  Erosion increases as the size of the abrasive decreases.  Effectively mixing abrasive with high pressure air and keeping the machine from wearing itself out quickly is a significant engineering challenge.  The AccuFlo® was designed around the following principles.

Keep it Simple

Our engineers focused on avoiding turbulence at all costs, especially when introducing abrasive into the air stream. Bends and complex shapes focus the abrasive force, which causes rapid wear and tear within the system.

Keep it Slow

We believe that particle acceleration should only happen at the nozzle.  Any change in the diameter of the hose or passageway through the machine causes a change in abrasive particle velocity.  Particles traveling at higher velocities wear out the inside of the machine faster.  Changes in diameter of the internal passageways also cause more friction within the blaster.  Any increase in friction reduces the amount of pressure available at the nozzle for particle acceleration.

Make it Accessible

Machine wear is inevitable in an abrasive environment.  Eventually any component that comes in contact with the abrasive media requires replacement.  The AccuFlo was designed so that essential components exposed to abrasive are accessible and do not require an engineering PhD to replace.  The modulator can be replaced by removing two screws that attach the cover.  The mixing chamber is accessible from the outside of the unit with an adjustable wrench.  Cycle and hour counters help set routine maintenance cycles for those wear parts.

All AccuFlo models have also been designed to be CE and RoHS compliant.

How Comco's Simoom Technology works in the AccuFlo

Featuring Simoom® Technology

During the early stages of the AccuFlo’s development, we prioritized creating a media mixing technology that was superior to the modulated feed used in our older MicroBlasters. We found that while the modulator itself was a great way to fluidize very fine abrasives, more could be done to intensify the pulsing mechanics of the system to create a more streamlined flow path and reduce turbulence. Simoon Technology is the result of several years of this research and development.

The PowderGate valve provides a more reliable abrasive flow mechanism than a traditional pinch valve.

The PowderGate® Valve

Originally released as part of our PowerFlo and DirectFlo line, the PowderGate Valve replaced the traditional pinch-valve which simply crushes a soft abrasive hose.  The PowderGate Valve proved to be tremendously wear-resistant and functional in harsh environments. So, we redesigned it to work in our AccuFlo blaster, too.  This scaled-down version fits neatly in the abrasive mixing chamber on the tank, features a straighter flow path, and sits in an easily-accessible spot on the side of the system.  Comco’s PowderGate Valves last hundreds of thousands of cycles in a production environment without maintenance.

ComfortGrip® Handpiece

Long hours blasting do not have to be hard on your hands!  AccuFlo nozzles have the same internal geometry as Hi/Performance nozzles with the added bonus of a well-designed holder: the ComfortGrip Handpiece.  This well-designed stylus provides the ultimate in comfort and performance. It has a cushioned grip with a natural feel, and it is less resistant to motion than most handpieces.  Simply, the ComfortGrip Handpiece enhances control and reduces fatigue.

Even better, it eliminates the need for a nosepiece and is easier to fixture.  The hose connects the nozzle directly into the two-piece ComfortGrip.  That means fewer parts come into contact with abrasive, which in turn means less need for parts replacement. The ComfortGrip Handpiece is compatible with most popular nozzles sizes (0.018″, 0.030″, 0.046″, 0.060″ ID).


The AccuFlo ComfortGrip handpiece is ergonomically designed for operator comfort and engineered for longevity

Optimized for Your Application

Each AccuFlo comes with a selection of nozzles and abrasive.  Work with our Technical Sales department to ensure that your system is configured exactly the way you need it. Better results come from better preparation.  The AccuFlo is available in a wide variety of configurations to meet the needs of your process.

The following options are available:

  • Standard or tall tank (one or two liter powder capacity)
  • Standard pressure (125psi) or high pressure (185psi)
  • Constant air-bleed model for working in wet environments
  • Electronic regulator for automation environments
AccuFlo standard AF10 and tall tank AF10-T models

Adaptable for a Variety of Production Environments

CCR with Comco AccuFlo and ProCenter Plus

If working with a manual or fixtured application, the ProCenter Plus easily completes a Microblasting system when paired with our AccuFlo blaster.  The ProCenter Plus combines a powerful dust collector, a chair-height work chamber and air dryer into one compact, freestanding unit.

Comco Advanced Lathe LA3250 powered by AccuFlo abrasive blasters

The AccuFlo easily integrates into our automated systems as it delivers a uniform abrasive stream, resists wear exceptionally well, and accommodates an AutoFill option.

AutoFill "endless tank" option for AccuFlo

One of our newest technological advances is AutoFill. When combined with the AccuFlo, AutoFill is the perfect solution for your automated set-up.  AutoFill actively monitors the level of media in your AccuFlo tank.
