Steve: The one we have, which I now believe is called Raask, not Rassk, is air powered, it uses shop air to create suction via venturi effect, I believe, it is a little noisy when it is in use. If you have access to the MB SSEP catalog, the business in Iowa (AGA) is listed in the catalog on the page where they show the MB (Tacelmite, or whatever) oil extractor. Just tell them you want the "standard" adapter, it took a couple times before I got the correct one. I finally told them it's the one that treads onto the shut-off valve, then i got it. Let me know if you need help contacting them, I may have a part number for the adapter as well....Gilly
