The Siren Board

I have a question for those with more knowledge. I happen to end up with in my possession a 25hp regenerative blower. Wondering if I was ever to acquire a thunderbolt head would it work in place of a roots blower? This is the blower I have:

It's the largest one, rb-1525. Performance curve on page 9

Interested in any thoughts, thanks.
