Variable Air Volume Controllers | 3 / 24 Description OPTIMA-LV-R (RI) is a Variable Air flow Volume (VAV) contoller installed in circular ducts for demand oriented ventilation. It can operate in large air velocity range and it is especially intended for precise flow control at low air flow velocities down to 0,2 m/s. It is pressure independent in range of 2 Pa to 600 Pa. The electronic controllers can operate for air supply or air extract.

Variable Air Volume Controllers | 21 / 24 Installation, Maintenance & Operation OPTIMA-LV-R (RI) is mounted directly in a spiro duct by a rubber gasket tight connection. Operation temperature range: -10°C ... +70°C in the duct, -5°C ... +50°C on the actuator. Important: In installations with higher hygienic standards like hospitals the service openings for cleaning shall be foreseen in the duct closely in front and and behind the VAV unit.
