Our most powerful and flexible air moving system, the System 1 is available in two versions. The in-line version is suitable for indoor use, while the EXM version is mounted in a weatherproof enclosure, suitable for outdoor use in virtually any climate. Both can move over 100 CFM while producing very little noise, thanks to a precision-balanced rotor. The in-line version is now Energy Star rated; airflow has been increased by 40% to 140 CFM, power consumption has been reduced while noise level remains the same.

Both versions include the centrifugal blower, 8’ of flexible, sound-absorbing tubing (6”OD/4”ID), and a 6 1/4” square hot air collector, a cross between a funnel and a flange that simplifies connecting the tubing to a flat surface, such as a cabinet back. (This fitting is ONLY included with the 4” System 1.) The in-line is ready to plug in to any of our thermal switches or an AC outlet; the EXM is ready to be hardwired.
