Congratulations, the Comco AccuFlo® model AF10‐E you have purchased incorporates the latest
development in micro‐abrasive blasting – Simoom® technology.
This patented method of mixing air and abrasives delivers a steadier, more consistent stream of abrasive
allowing you to process parts efficiently and with uniform results. Here’s why it works so much better than
other micro‐abrasive blasters.
How does Simoom® technology work?
Activated the blast and the modulator opens and closes 50 or 60 times per second (depending on local
power supplied at 50Hz or 60Hz), producing pulses in the air stream. The rapid change in air pressure
fluidizes the abrasive above the orifice. The powder is then drawn through the orifice into the mixing
chamber where it enters the air stream and exits the AccuFlo® through the PowderGate® valve traveling out
to the nozzle.
The strength of these modulated pulse and the diameter of the orifice determines the amount of abrasive
that drops into the mixing chamber. Three mechanisms enable you to change the amount of abrasive in the
air stream: the tank orifice, abrasive blend and bypass tube.
Tank Orifice: A larger orifice increases abrasive flow. In most cases the orifice should be at least 5 times the
size of the average particle size, but not larger than the nozzle.
Bypass Tube: The bypass tube creates an alternate path for the modulator pulses, bypassing the orifice. A
larger bypass tube dampens the impact of each pulse, reducing media flow.
Abrasive Blend: The abrasive blend changes the strength of the pulse by allowing some air to bypass the
modulator. With less air passing through the modulator, the pulse weakens and less abrasive is fed into the
air stream. The abrasive blend valve allows you to fine tune the abrasive flow.
