I have a headroom problem, and JDS is about all that will fit. Has anyone used one? They claim to have a different impeller design that gives better suction at higher static pressures; if true, that is good since I will be using it with a 4" hose. Sadly I just don't have the room for permanent installations; all my tools are mobil.
The JDS salesman says that the 3hp would be overkill; for one tool I would get all the suction I could use from the 2hp. But I don't want to buy a small machine and have to upgrade latter on; that is just false economy. I have done that a few times in the past (okay, many times...) and regretted it. Plus, it seems to me that a 3hp has to perform better than a 2hp on something open like a CMS. Any thoughts on this issue?
