John I guess we will have to disagree here. These units make absolutely no sense to me from a restoration point of view. If it takes 6 of them to produce 5400 cfm and those 6 air movers use 11.9 amps. Then there are many more choices out there that can produce enormously more cfm and use only slightly more amps per unit. I don't know about you but I still go out on 90% of all the water restoration jobs that my company receives, which is over 200 a year. To do my job properly the most cfm with a low amp draw is real important. Low cfm and low amp draw equals longer dry times and frustrated customers and insurance companies. When buying equipment the last things you should consider are things like stackability, ease of carrying, pretty molded plastic, easy to take apart and clean, etc. While these things are nice, they don't dry a building. If you are buying equipment because you can carry it easily, or it is stackable then you probably shouldn't be drying buildings. Just my 2 cents. It's a good debate though.
