"Hello, I want to start by thanking you all for this website, and all the info. herein. And saying that I just purchased this Extractor, and have not used it yet. So please bear with me, I am a carpenter, not a scientist, and this is sounding pretty scientific, the more i read. OK, I have a BHOgart closed loop extractor. I also have a, Robinair Cool Tech 34288 Air conditioning recharging system. Now in case you are not familiar with the Robinair AC. machine, it appears to have all the components of a closed loop Extractor in that, it has a Vacuum Pump, Recovery Pump, scale to weigh your material, filter dryer, condenser, Gauges for high and low pressure, Manifold, and the hoses to hook it all up. Google the make and model for all the info on, Robinair 34288. To the untrained eye, it would appear that you could simply hook up the hoses and turn it on. my question to you is, Can I evacuate the R-134a refrigerant from the AC recharging system, and replace it with butane? then hook low pressure hose to the top of the Extractor. And hook the high pressure hose to my collection chamber and pull an extraction? Thank You, and I look forward to talking Extractions with you Rick"
