So I ordered this exhaust/draft inducer chimney fan from Gemi Elettronica in Italy. I was suppose to receive the "Cortan Steel" Finish, but they first sent the "Professional Steel" finish. They asked if they could send me a Cortan cap and base and I just keep everything they already sent which was fine. So now I have a stainless steel chimney cap and base with no fan. Good for those needing a chimney cap to keep creatures out. These are $1000 USD fans, so it is a high end product.
AISI 304 Stainless Steel
Adjustable AISI Stainless Steel base brackets make it adjustable to fit any chimney square or rectangular from 20x20 cm up to 43x43 cm
