Thanks for your question Benny, and we apologize for the delayed response.
No, this Cast Iron Fan Motor is not comparable for your SP48-12 model. You'll want Beverage Air part #501-087B. We do not currently stock this part, but we special order for customers on a daily basis. Please give a member of our Tundra Restaurant Supply team a call at 1-888-388-6372, and we'll be happy to get you the part you need.
can you tell me the dimensions and the threaded rod size of this product?
what is the circumference and length (see image) from the back edge to the base where the threaded rod extends? Trying to see if it will fit in the space I have and if my fan blade will also. Thank you.
