Graco 3A7526G, PR-X Operating instructions

  • Hello! I'm your chat assistant and I've carefully reviewed the user manual for the Graco PR-X series of dispensing systems, including models 25R129, 25R128, 2001180, and 2001181. This document outlines the setup, operation, safety measures, and maintenance for these fixed ratio systems. I'm ready to answer any questions you may have about it, from installation and troubleshooting to specific operational parameters. Feel free to ask!
  • What is the maximum working pressure of the PR-X system?
    What is the maximum air inlet pressure?
    Is the PR-X system approved for use in explosive atmospheres?
    What should I do before using the equipment?
