• Variable Speed Control Switch


The Variable Speed Switch allows you to control the amount of air flow from the Duct Fan. The fans will run at the rated MAX CFM's and the switch allows you to turn the rate down if you are getting to much air flow. The Variable Speed Switch is the only switch recommended for use with the Duct Fans. These are single speed motors so don't make the mistake of purchasing a ceiling fan switch to operate this fan. Instructions for installing Variable Speed Switch *** Please note- It is highly recommended to have a professional electrician install all electrical components.***
