    General issues involved in operating machinery. Working with a Device that is Pressurized The DirectFlo uses pressurized air to perform its basic function. While Comco's blasting machines incorporate relief valves and check valves to minimize the risk of an accident related to air pressure, Comco also recommends the following: √...
  • Page 6 The DirectFlo uses several types of abrasive media that should not be inhaled or ingested in large quantities or maintained in prolonged contact with the skin. When working with the abrasive media, Comco recommends the following: √ Do not direct the abrasive blast on bare skin or face/eyes.
  • Page 7 Some powders, if allowed to collect inside the machine, may cause electrical shorts. Material safety data sheets (MSDS’s) for all abrasives distributed by Comco are available from the Comco factory. Every powder shipment includes an MSDS. Contact the Comco Customer Service department to obtain extra copies of any MSDS.

    Chapter 1: The DirectFlo 1400 Overview The Comco DirectFlo Model DF1400 is a bench-top machine that delivers a precisely controlled stream of micro-abrasive particles at high velocity. With the appropriate abrasive powder and the necessary adjustments, it will clean, deburr, cut or drill any material, particularly hard or brittle ones.

  • Page 11: How The Directflo Works

    To operate the DirectFlo from this point would simply require picking up the nozzle, pointing it at the item to be blasted, and depressing the footswitch to begin blasting. What happens when the machine is actually in operation is explained on the following pages. Comco Inc. Issue Date: January 2009...
  • Page 12 Since the air flowing from the regulator into the mixing chamber is at basically the same pressure as that in the tank, the upward force of the air keeps the abrasive in the tank. At this point, little or no abrasive is being injected into the air stream. Comco Inc. Issue Date: January 2009...

  • Page 16 These dust collectors have both high airflow and large filter areas to keep work areas clean and dust free. The Comco DC2100 is a suitable dust collector for most micro- abrasive blasting applications. In heavy usage, multiple blaster, and automated applications, the continuous duty DC3000 dust collector is recommended.
  • Page 17 DF1400. If the WS2200 or WS6000 WorkStation is used, it requires 40 watts. The DC2100 Dust Collector, if used, requires about 16 amps (115 VAC) for its 1-HP motor. Actual voltage required for each machine will be found on the nameplate. Comco Inc. Issue Date: January 2009...
