Expand your horizons! No longer bound to the confines of the home, our new line of EXPAND travel circulators were designed to be taken â on the road, in the air, out the door. A quick pull and the EXPAND4 snaps into position, and collapses down in a wink for small storage. Two speeds ensure you are encompassed by cooling air comfort all along your journey. With a built-in carry handle and integrated cord storage, EXPAND4 might just be the best travel companion you ever had.
