I am at a loss for trying to find this part, it seems like only 1 or 2 manufacturers produce this, But I'm sure it is more common than that. This is an attachment that goes on to the inlet/outlet of regenerative blowers, and with a solenoid, allows the output port to switch between vacuum pressure and high pressure air. I've attached a picture of the only one I was able to find, labelled a "diverter valve". I'm hoping someone with more experience might have come across this and can either correct the term I'm using, or direct me to a vendor who might carry something like this. (Ideally in North America) Really appreciate any help. Thanks!
