Large 3 Phase 480v Exhaust Fan Startup

[@67tr876]

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.

[@1944johndeerel]

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

Bro, Make Video! Interesting! pls! Respect from UA!

[@aidenp265]

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

[@douro20]

How big is that motor, about 5hp?

[@vacexpert2020]

Looks about the same size as the Leeson 15hp motors where I work

[@ihysnxgs4014]

Sounds like my Lennox merit heaters starting up😂

[@PocketOperatorGuy]

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

[@levigaming-1]

Kinda sounds like a thunderbolt by federal signal starting up

[@duckiesquad9]

It does!

[@douro20]

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

[@008626]

Another motor, a dead one I assume

[@intelboydj1]

It sounds like a subway train

[@J19_vlogger74]

Sounds sort of like the EAS Attention Tone.

[@twmax4137]

That motor is to small for that gigantic fan

[@dylanreischling4151]

TΩwmaX that motor probably looks small but is well sized. 3 phase motors can look small but put out a lot of power

[@kanalname5996]

Maybe the fan is not as big as the white box.

[@SeanBZA]

Belts need changing, one is delaminating.
