Dave,
I am not a electrician. So I really don't know the motor type.
I called the factory on this SPA blower and talked to there tech guy.
Told him what I wanted to do. Off the record he said they will run fine on the dimmer down to 18 volts. He has tried it. BUT he said that if I did hook it to a dimmer it would void the warranty! So of course I am not going to do that!:)

Chris, does your motor have a capacitor on it ? The capacitor will be enclosed in a metal cap like thing about 3" long, 1 1/4 across the base and normally have a rounded top about 1-1/4" high. About big enough to put a 3" peice of a hot dog inside.
If it is a capacitor start motor, you should be working on a
"Plan B" because there is a good chance the motor will crap out, especially if you run it slow. To be assured of a reasonable life exepctancy you need a "shaded pole" motor. They do not have capacitors. The most common place to see these is in ceiling fans. That is the kind of motor Leader and others use for air under the fire systems.
If the sap guys will take it back, ship it and order a proper high pressure radial blower with shaded pole motor from Grainger or McMaster Carr. After all that work you won't want to go without your air system 6 hours after the season starts.
Brandon,
New to the site and sugar from CT. I'm trying to install air over this year with black pipe manafold. During your research is it nessary to enclose the manifold? Or was it to keep the fire box free and clear?
Look forward to hearing from you or anyone else that has an idea on this.

Maple1, somewhere in this thread is a link to the research paper done on the air over fire. Black pipe is covered with ceramic insulation or refractory cement. Black pipe will not hold up to the heat in the fire box. That is why some of us used Stainless as it will.
GaryR,
Thanks, I will be tapping tomorrow and will install the pipe for this season. Hopefully it holds up. Always work on new items days before the crazyness starts. Don't think I'm the only one.
you will need to cover black pipe w/ refractory cement or arch blanket or both.
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

According to the research I did a few years ago, you can run a PSC(permanent split capacitor) motor with a fan speed control/rehostat but not a capacitor start motor. Not 100% certain on this but it is what I was told by some electrical experts I was referred to by Grainger.
Unless I messed up my research I believe you can use one of these on capacitor start motors.

Here is the manual. In the manual it says it can be used with a PSC motor which is a permanent split capacitor motor, also known as a capacitor start motor.

Hopefully I'm correct or I just bought and installed a $64 paper weight.
