Made from galvanised steel, reducers are the perfect solution to reduce the size of your grow room intake and/or extraction.
 
The size of your set up may require the use of a 10” extraction fan, but you don’t want to make a 10” hole in the wall (or building) to accommodate the ducting. By using a reducer, or a series or reducers, will allow you to scale down the size of extraction, or intake, to the required diameter and are available from 4” (100mm) through to 12” (315mm).
