    Comments about Mountain Air Vacuum Pump:

    This is pure fluid mechanics at work. This has no moving parts to break and requires no maintenance. It's another tool that just works. With a 30 gallon 5-HP air compressor I was able to run 90psi line pressure (dynamic) to this unit and it was able to pull and hold 28" of vacuum with no problem. I highly recommend it.

      • Q:

        if you use 90lb psi air there should be moisture in the air? &, how do you put the fluid to flush the system in
        Asked on 5/2/2012 by Joe from San Antonio, Tx

        • CUSTOMER CARE

          A:

          This Mountain Vacuum Pump Air with Part No. MTN8405 requires compressed air which means only a minimal amount of moisture is required. You basically need shop air to flush a system. The system needs to be broken down and each component is flushed individually, except for the compressor, dryer, expansion valve, and filter (if present). You can use mineral spirits or a can of flush which would be more than enough for one AC. For any further assistance please feel free to call 1-877-238-2623 and one of our representatives will gladly assist you with any questions or concerns you may have.
