Brent,
No this does not have a exposed motor like the Dayton units. So not sure it has a capacitor. I know what you mean but this is a self contained motor more like a shop vac type motor. I did not take it apart.
If any one wants to google it the just look for AquaPro spa blowers.
If it craps the bed I will be the first to say see "that didn't" work".
Regards,
SM
