  1. Since R290 and R600a have very low ODP and GWP...

    Since R290 and R600a have very low ODP and GWP ratings, and considering the explosion risk during service, reclamation, and recovery operations, the buzz seems to be to vent the stuff. However,...
  2. Standard refrigerant recovery equipment is not...

    Standard refrigerant recovery equipment is not explosion proof, and is therefore not safe for use with flammable/combustible substances. For systems where you know there is flammable refrigerant in...
  3. This issue was solved almost 2 years ago, but...

    This issue was solved almost 2 years ago, but some wholesalers may have not been selling the oldest stock first. In any event, if you do find one of the old ones, we'll still take care of you without...

    There's no reason we wouldn't have responded, if we got your email. Make sure you are emailing Support - at - appiontools - dot - com. You could try calling too, but we are going to ask for proof of...

    The diagram was recently updated, so there may have been confusion there. We updated the diagram to make it easier to understand.

    Email us and ask for the KTMV20 diagram/instructions, and we'll...

    It's accurate at atmosphere (760,000 is average micron level at sea level, but we're at altitude, so we're anywhere from 630,000-650,000). It's also accurate at 15 microns.

    You might notice that the AV760 is wirelessly sending its readings to the smartphone... you might also notice that it is measuring from atmosphere and down. And for accuracy, well... I think you'll...

    The trouble here is the lack of standardization of the pin-tip of the valve core. If we make the tool "loose" enough to catch worn, corroded, and oversized pins, then the tip won't always remove...
  9. The main things the maintenance video covers is...

    The main things the maintenance video covers is proper attachments, closing the valve halfway during evacuation periodically, and an overview of the assembly for replacing o-rings. Also, our kits...

    We are in the process of releasing new products this season, including the gauge shown here. It's doing what you see here... and more.
  11. Vacuum Rating Tools to 20 Microns with NIST-Traceable Gauges

    We've been asked many times to explain how the MegaFlow Valve Core Removal Tool ("VCT") is "Rated to 20 Microns," and how our tool differs from others. This video is a small-scale example of our...

    Not quick connect, standard threaded 1/4" Flare fittings. Yes, even the 1/2" hose had 1/4" fittings on both sides, no extra adapters (it helps that we can make our hoses however we want).
  13. The charts we published were from tests we...

    The charts we published were from tests we performed, trying to quantify the difference between the hose diameters. In those tests, we did our best to eliminate other speed-impacting factors... the...

    We're working on several others; we just posted a series on G5Twin maintenance, and a couple more to be posted here in coming days. We're discussing the ideas brought up in here, too, thanks!
  15. It's far from easy or certain to determine what...

    It's far from easy or certain to determine what is causing that slowness in every scenario... but in EVERY scenario I've been involved with, we've either demonstrated or been pretty sure that...
  16. Not a chart specifying CFM by hose diameter, but...

    Not a chart specifying CFM by hose diameter, but we've done some tests showing evacuation times related to the hose diameter. While CFM can be directly calculated, it is only tells part of the story:...
  17. I like where you're going with this, but there...

    I like where you're going with this, but there are a lot of factors that can significantly skew the results AND applicability of a test like this. Also, it would not be a simple things to isolate the...
  18. Valve Cores, Hose Diameter, and Evacuation Speed

    A frequent question we get is whether valve cores really affect evacuation speed. Considering that they block about 90% of an access valve, and create a torturous route for molecules to evacuate the...

    Very interesting video... I've only seen that occur when the quality of the vacuum pump oil has degraded due to saturation. You can't trust a sight glass to tell you the quality of the oil... drain a...

    I see you already bought the unit, it looks to be a 2012-built machine, and it does look new. That said, if you're ever trying to test the G5Twin, the test described is shown in more detail in this...
  21. The summary: 1/4" fittings DO limit evacuation...

    The summary: 1/4" fittings DO limit evacuation speeds, albeit only slightly. You can still evacuate faster through 1/4" fittings, since this restriction only accounts for a small portion of the...

    Some other people here have been confused about "friction": once you are deeper along in a vacuum, and the inertial forces are no longer prominent (molecules moving along much more lazily), it's not...

    While I couldn't state a "universal" fact on what's getting in there, here's the common contributors to the "slight discoloration" that can occur during evacuation (even with "new" systems):

    It's the other way around, the TEZOM oil is hydrophobic, it repels the moisture that comes into the pump so that the exhaust carries away moisture more easily. In a sense, it is opposite to what...

    There are numerous reasons why the Fluorotech machine you describe was not seen as a reliable, fast, or ideal recovery machine. The compressor that you described is a modified air compressor,...
