Sp11 vs Rv2

[Dill]

For the last 2 years, I've been running an RV2 in my woods. I picked up an SP11 too late to run it last season. Would it be worth swapping pumps? I know the RV2 isn't that big, but it barely costs anything to run usually under 20 bucks a season. Just not sure if the SP11 would move that much more air.

Dill, they are pretty much the same size. The RV2 should be 4.5 cfm. If the SP11 has an 0.85 hp motor on it, it would be 5 cfm. SP11's were also sold with 0.55hp motors, making them 4.5cfm. The SP11's are newer than the RV's. So depending on motor size you might be gaining 0.5 cfm.
