This heat transfer kit is designed to service three rooms from one intake room and comes with 18m of high quality R1.0 insulated ducting. It includes a Centrifugal 150mm Inline fan.
The items in this kit have been selected for the purposes of DIY installation. Please keep in mind that adding hardwired accessories (speed controllers, thermostats etc) may mean that you will need to hire an electrician.
