Peace be upon you. I have a large restaurant exhaust fan, 3 horsepower, Japanese KDK company, very fast, and God willing, superior power. I have its twin installed, and this one is not installed. It is new. Its wire has a feature inside the motor for temporary disconnection if you want to connect it to the electrical distributor. It is still under warranty. Size 38 length and 38 width. New, under warranty, and unused, and it comes with its invoice. Serious buyers can contact via mobile for credibility (mobile number appears when you press the contact button). Please, only serious buyers should contact, and I will be considerate.
