Awesome blower !! But that motor looks way underpowered I gusse they did not need a lot of cfm from that so they put a small motor.

We have a lot of fans like that where I work, some much larger

That’s an old Sturtevant Silentvane or Multivane fan. It’s original motor would of been Western Electric or Westinghouse 15HP. There’s a lot of them installed from the 20’s to 60’s

Sounds like a Bradford White Water Heater Vent Fan

Kinda sounds like a thunderbolt by federal signal starting up

There must not be a lot of weight behind that impeller. It's a pretty small motor.

Sounds sort of like the EAS Attention Tone.

That motor is to small for that gigantic fan

What is the device sitting on the floor next to the motor?

Belts need changing, one is delaminating.
