British Columbia-based Ecco Manufacturing announced it’s the only maker of a new HVAC market product that is both a ceiling fan and diffuser. Officials say the Dynamic Air Diffuser does not need electricity, using instead the forced air created by a building’s HVAC units. Air goes through the diffuser’s hub and the linear slots of the fan blades, allowing the fans to turn. The fans’ even airflow keep occupants comfortable. Custom colors are available.
