No, no, absolutely no. I bought two things recently that were rated with horsepower as the power differentiating value. My leaf blower has a sticker that says 25 peak Hp. I carry it in one hand or on my back. A 25 Hp motor of any kind is heavy, something’s not right. My shop vac is awesome. It too has a sticker claiming 12.5 peak Hp. I plug it in to the same outlet I use to plug in my shaver. I do not have a fuse in my panel strong enough to run a 12.5 Hp motor. Something is wrong. The above tools are using Hp to measure something but it’s not the power of the electric motor.

In dental dry suction the vacuum pumps are all very different. Some are high flow, some with oil some completely dry. As discussed in another note it’s really the matching of volume to vacuum that creates the velocity to make things happen.

More horsepower does not change the physics of how much air you can suck through a bunch of holes. Most of the extra flow gets sucked through a relief valve.

The water ring pumps have a good cfm/hp ratio. If you look for a dry system that matches the hp of your wet vac or a comparable new wet vac, then you can be sure you are getting a pretty good pumping system. More Hp usually means more of something, either size, weight, airflow, heat, noise, etc. If you are buying more of anything pick volume but make sure you can get the over stated flow through the open holes in your suction tools. See flow vs. volume.
