Pentair Minimax pool heater obsolete parts

Pentair Minimax
HTR-400-NT-STD-NH-standard
Model: 400 DV
Serial: 06040391:

The fan blades / turbine of the blower assembly disintegrated. The part number is 472374 but I cannot find a supplier carrying it. (The motor and housing is fine. Just the actual fan blades needs replacing). Apparently this part is now obsolete. I think it crazy to trash a fairly good heater because of a $200 part.

Does anyone know if one could obtain a suitable substitution, or even get just the actual “fan blades” and save the motor / assembly?

Any other suggestions / options will be appreciated!!!

The part number you left is for the entire assembly.

Typically draft inducers come as an assembly. Some have replacement motors but I've never seen just the replacement blower wheel offered separately.

However there are many companies selling replacement blower wheels. You could measure what you have and check online for a replacement based on size. The direction of rotation is also important.

Thanks!

Not sure if I can measure it (diameter / # of blades etc. It is so mangled an torn up. Not sure where to begin search. The other issue is, it looks like it may be hard to get off motor axle. I have started some PB-blaster.......

What sealant / heat resistant caulk do you recommend

PJMAX,

Well, I found a supplier for the fan. Thank you for steering me in that direction.
Next question: What caulking do you recommend using to reassemble the the fan assembly and where there may have been a “gasket”. I assume a heat resistant silicone based product will be best?? Is rating up to 600F adequate?

thanks!
