Tjernlund’s “Balance Booster” reversible transfer fan consists of a high-performance fan and Easy Flip chassis that are installed in-line with the duct. The kit also includes two 4” adjustable grilles, a plug-in wireless receiver and remote control, plus mounting hardware. The system requires installation of owner-supplied 4” metal or PVC duct from the basement to the upper level through an existing chase, backs of closets, framed and dry-walled corners, exterior chases or other between-floor passageways.
