Trying to locate a Damper motor

[vet]

I'm an A/C Tech that is looking for a specific type damper motor. its used in a dryer type system commercial, its just attached to a 20 in. pipe and is only activated with a toggle switch, 120 volt on and off is spring closed. Only info I have is ( Multi products,5amps, 60hz,120 volts, class F , UR , 82000. PHYSICAL DEMINSIONS.
2 3/4 in tall, 1 1/2 in wide, 6 in long. Just need some place to start looking at, most searches only showing me residential type dampers. Maybe some one out there might have a place to look at on the internet !

Whats the damper size and what is ( pressure?) it closing off against ?

If you can find a damper with the correct dimensions and inch pounds rating for that typer of damper, it won't matter which one you use,

You can usually figure 6 inch pounds per square foot of damper,

Thanks, I never broke it down to that simple a fudge factor.
