1 OPTIVENT UTRA VAV dmper TECHNICA DATA

2 2 OPTIVENT UTRA VAV DAPER USA, UDA USA UDA VAV dmpers re used to regulte nd control ir flow for supply nd extrct ir. They re highly verstile, nd cn be used to control room temperture nd ir qulity, mong other things. The OPTIVENT UTRA offers ll benefits from the Optivent series of VAV dmpers, but with the dded ultrsound technology for mesuring ir flow. With high ccurcy in the whole irflow rnge nd excellent resilience to dust, the OPTIVENT UTRA works well in ll types of environments, lso more chllenging ones, such s clssrooms nd ptient rooms. No pressure drop of the ir flow mesurement nd brod mngeble irflow rnge mens high comfort in the whole of the building nd in every sitution. This well-blnced system hs no physicl probe tht cn cuse turbulence nd noise, for silent nd mintennce free opertion.
