Below are the IN3620 Operating Specifications:

 

Motor specification - Watts 550, RPM 1465, 3 sones measured under the installation location with standard attic insulation installed and attic hatch closed.

Shown above is the fan with steel chains at the top for hanging from your rafters. It has a collar on the back for  one 18 inch duct for maximum air flow.  To be sure that every bedroom can get maximum ventilation with the door closed, look for our “door jump duct” kits.

Invisco includes a 6 foot long AC cord (longer if you want as an option). This kit also includes one Vari-Speed controller to enable you to take advantage of continuously variable speed from high speed to as low as you want. Note that the air flow is cut by 75% at half the rpm. And, of course, the sound at low rpm will be almost silent. Also note the kit includes a beautiful white ceiling frame and cube core grille. The cube core grille is very important to minimize the sound of the air going up.

    

This kit also  includes 15 feet of 18 inch uninsulated ducting (no insulation is needed because you will put the air shutoff damper right above the hole in the ceiling).

The kit also includes an 18 inch damper that  has straps to hold it down so you can attach the duct without it moving.

A damper is included for above the hole in your ceiling. It has 2 straps to hold it in place while you attach the duct.

Don’t forget the best news – your Invisco system is guaranteed for 15 years. The components are highest quality.
