Hi Guys:
It looks nice........... "Design" Patents can be put on anything.
Yes, these blowers are lighterweight than lobe type. The problem forseen by others who looked at these type blower is, they do not produce as much pressure (Hg) only volume (CFM). And they are aluminum. A side by side comparison, with a Hg meter would be nice. Also the wearability of the aluminum remains to be seen.
Thx,
Dale
