Direct drive fans confuse HVAC nerd

by

Here’s the fan, a direct drive utility set, designed for 10000 cfm at 2” of static pressure.

Here’s the performance, extrapolated from Loren Cook’s selection program.

Wait, stop, hold on.

The smallest fan with the highest brake horsepower has the smallest motor. That seems backwards.

Can a 7.5 HP motor be applied to the 245 and 270 CPS? And a 5 HP motor to the 300 and 330 CPS?

Nope.

In this case, the only fan that should have a smaller motor is the 225.

That doesn’t make any sense!

It does.
