Air transfer system
November 1, 2012
Tjernlund offers a way for homeowners to permanently improve whole-house comfort. The system is designed to pump cool basement air through a duct to the hot upper level during the cooling season and warm upper-level air down to chilly basements in the winter. The heart of the system is a Balance Booster reversible transfer fan consisting of a high-performance fan and Easy Flip chassis installed in-line with the duct. The system requires installation of owner-supplied 4” metal or PVC duct.
