2017Advantage Diffusers Developed

SPECIFICALLY DESIGNED FOR INTEROPERABILITY, The Advantage VAV diffuser provides personal control within a zone by modulating the flow of supply air to a particular area. With the ability to monitor load, supply air temperature, and flow, the Advantage VAV diffuser is an exciting alternative to VAV terminal units. Native BACnet™ ensures that the Advantage will exchange data with products from other vendors on any BACnet™ MS/TP DDC building control network.
