In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
I just noticed Spirotherm, in the most recent edition of Contractor mag which I have received today, just came out with a combination Air Seperator, Dirt Seperator, and Hydraulic Seperator all in one. I take this more seriously than some of competitions hydraulic seperators, because this unit, which comes in sizes as small as 1" for residential applications, actually has full media from top to bottom which will give it much better performance in air & dirt seperation.
