Building a vent system for a coffee roasting client, and need performance curves for the following Double inlet, forward curved Centrifugal Blower.


Lennox industries F112-3/4-8S
This is an oldie, and Lennox doesn't have any info that they cared to find for me when I called.

A general crossover comparison, if possible to DELHI would be ok, too.

Please direct me to any sources if that's easier.

Thanks,
Colin
