Page 3: Simoom® Technology
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. For more technical details on Simoom technology, see US patent #7,297,048. tech@comcoinc.com... -
Page 4: Set-Up Procedures
Make Connections 1. Place the ComfortGrip® handpiece inside the work chamber. 2. Place the open end of the vent hose into the back of the workstation or into the dust collector hose. 3. Connect the power cord and the blast control cable. 4. Connect the air supply to the “Air In” fitting (using ¼" tubing provided in the accessory kit). TO NOZZLE(S) INLET AIR FITTING THE ABRASIVE HOSE FROM THE VENT HOSE POWDERGATE VALVE RUNS IS ROUTED DIRECTLY TO THE NOZZLE. THROUGH DO NOT ROUTE THIS HOSE THE VENT THROUGH THE VENT PINCH! PINCH Add Abrasive Remove the tank cover. Fill the tank with powder. Do not fill above the top of bypass tube. Replace the tank cover and secure (only ¾ turn required). Always maintain a 10 psi buffer between the AccuFlo pressure setting and your compressor. This protects against abrasive flowing backwards through the machine. 1‐818‐841‐5500... - Page 5 AF10‐E Control Connector Blast Control: Pin 1 provides 115VAC power from the AccuFlo. The host must provide a switch to put this voltage back in to Pin 2, which will cause the blaster to blast. When Pin 2 is left floating, the blaster will not blast. 200mA of current is typical. PE: Pin 4 provides an optional bonding path to Primary Earth through the AccuFlo. If the host is otherwise bonded to PE, do not use this pin. Regulator Control: The regulator must be powered by 24vdc through Pin 7 and ground through Pin 6. The regulator requires 60mA of current. The blast pressure is set by providing a 0‐10vdc signal at Pin 8, which corresponds to a pressure of 0‐148psi. The internal resistance of the regulator’s input is 100ohms minimum. AF10‐E Cables and Controllers Cabling and control depends on how the user desires to control the AF10‐E. Use the above table to determine which cable to use. If the AF10‐E is paired with an AutoFill unit, refer to the AutoFill manual for additional wiring information. Tech Support: 1‐818‐841‐5500...

Tank Orifice & Bypass Tube TANK ASSEMBLY MB2200‐10 (Standard) We have configured the AccuFlo® for your MB2200‐20 (Tall) particular application. BYPASS TUBE Start with these settings. MB2265‐x You have the option to adjust settings. Minor changes in powder concentration should be made with the Abrasive Blend Control on the front panel. For more significant changes, the abrasive concentration in the air stream can be made leaner (less abrasive) or richer (more abrasive) by changing the tank orifice and bypass tube. Contact a Comco Tech Support Specialist for information on additional options. • Change the tank orifice using a ¼" nut driver. • Unscrew the bypass tube and lift it out of the sleeve. Using the chart below, select the tube you desire and insert it in the sleeve. Finger tighten only do not force.

Page 9: Maintenance Counters
Maintenance Counters For easier maintenance there are two counters on the front panel. The CYC counts the number of blast cycles on the AccuFlo (each time the PowderGate® valve opens.) Abrasive type and blast pressure will impact maintenance frequency, but typical configurations will last more than 250,000 cycles before needing maintenance. The HRS counter records the number of blast hours (i.e. actual time the modulator has operated.) Your maintenance requirements may vary with your application. The modulator should be replaced after 5000 hours of operation. AccuFlo® Modulator To replace the AccuFlo® AF10‐E modulator: • Disconnect 3 colored tubes from the modulator and the electrical plug from front panel. • Remove the two screws holding the modulator to the bracket using a Phillips screwdriver. • Install the new modulator in reverse order, making sure the two grommets remain in the bracket.

Page 10: Troubleshooting
Troubleshooting If the unit does not pressurize when you turn it on: • Is there power to the unit? Does the light on the power switch illuminate? If not, check the power cord connections at the back of the unit and at the power source. Check the fuse. • Is the air line connected? Are the upstream valves open? Check the inlet air supply. • Do you hear air escaping from the unit when it is turned on? Check that the inlet air, vent hose, and abrasive hose exiting the PowderGate® valve are connected properly. See the set‐up guide on pages 4 and 5. Make sure the tank cover is securely fastened. If you are getting air through the nozzle, but no abrasive; or if the cutting action decreases: • Is the powder tank empty? Refill. • Is the abrasive in the tank damp and sticking to the walls? Replace with fresh powder. Check that your air dryer is working properly. • Is the tank orifice plugged? Empty powder, remove orifice, and inspect. Check to see if your supplier of abrasive powder is providing high quality material. For details see the Support section on our website. • Is the modulator functioning properly? You should hear a buzzing sound when the blast is activated. If not, the modulator may need to be replaced. For further details contact Technical Support. If nothing happens when the blast is activated: • Is the nozzle plugged? Remove and inspect. • Is the PowderGate® valve failing to open? Contact Technical Support. If you suspect the PowderGate® valve is not closing completely: When the PowderGate® valve closes, place a finger over the end of the nozzle for 3 seconds. When you remove your finger– is there a small puff of air? If so, there are two possibilities: • The PowderGate® nose is worn and can be replaced as described above. • The abrasive mixture may be too rich. Reduce Abrasive Blend adjustment on front panel, or check the Bypass Tube Chart for a leaner mixture to handle your nozzle size. Prevent Moisture and Oil Contamination Contamination of the abrasive powder from moisture and/or oil is one of the most common problems ... -
