The eight-inch Sunleaves In-Line Duct Fan is a 60-watt unit that pushes 210 cubic foot per minute (CFM). 

This inline duct booster is lightweight, energy efficient and cost effective. It works with either standard sheet metal or flexible ductwork.

Perfect for boosting air flow through long runs of ventilation ducting or to push air through filters.

Sunleaves In-Line Duct Fans are easy to install:

Simply cut your ducting crosswise, then slide each side of the booster into each opening.

They're crimped (pleated) on both ends for easy insertion into your ducting.

Sheet metal screws for attaching to sheet metal are included. (Use heavy-duty nylon cable ties or duct tape on flexible ductwork - not included.)

These 8" booster fans run very quietly and come with a pre-wired power cord.

Covered by 1-year warranty. Made in USA!
