From the managing agent for Westage Towers East Condominium:
"Over the last year and a-half, I’ve bought and installed about 60 AURA BI-FANs. Installation was easy. We haven’t had any breakdowns with these fans. They conserve energy and offer better ventilation.” Below are pictures of a recent replacement of an older vent with the Aura Bi-Fan. Notice in particular the big difference in amperage between the old vent and the new Bi-fan replacement."
