Duct Reducers. Upgrade your duct fan without upgrading your duct lines!

Duct Reducers are a great way for you to improve your airflow without upgrading your
existing duct lines! If your looking for higher CFM rating's but feel your duct lines are
limiting your options Fear Not! These duct reducers come pre-crimped for easy
installation into your existing duct lines as well as the duct fan.

As an example lets say you have a 6 inch duct line but would like the CFM output of an
8 inch fan. Simply purchase a set of the 8 to 6 reducers!The 8 inch end mounts to the 8
inch duct fan and the 6 inch ens mount inside your existing duct lines! Its as simple as
that and because the duct reducers are pre-crimped all you have to do is slide the
reducers onto the duct fan and secure with a few sheet metal screws which are
provided with the duct fan.
