| I use an old anhydrous amonia 500 gal two wheel trailer tank with suction fittings on the very top. I have a York A/C type compressor, suction side to the tank, powered by a small Honda engine. It will pull the vacuum to about 20 in. at this altitude. Parked outside the shop, I just wheel the drain pan out to it and vacuum out the pan. Oil changes on irrigation power units , I have a valve in the oil pan with 1" cam lock fittings to hook up to the tank and vacuum out the oil. It has served very well for the last 18 years. | |
