Option 2: Request a change order to the specification so that you can provide what is available.

About 8 HP, it's 17,000 cfm at 2.25" in round numbers. Figure a 10 HP nameplate motor.
What the vendor is saying is, We don't make that fan.

If the fan meets all other specified criteria (centrifugal, upblast, inline, etc) and fits in the allocated space, use the belt drive fan.
