Not sure if this is the right section but just saying hello will post some pictures up soon of the single direction flow bench I have built/building. This all started when I was donated some redundant equipment.
I am using an industrial blower powered by a 7.5HP 3 phase motor (soon to be ugraded to 10HP) controlled with a Siemens VSD. The goal was to build a 600-1000CFM bench capable of flow testing various items at actual flows if possible.
