The OPTIMA-S-FC-BM is a variable air volume controller intended to control the flow volume of supply or return air. The product is designed to be installed into rectangular ducts. It is ideal for all applications where a variable airflow volume in ventilation, cooling or heating is required. Available in different sizes, it is typically installed in offices, hotel rooms, meeting rooms, healthcare premises and residential settings. It has an air volume range of 144 m3/h to 47500 m3/h, and an operating range of pressure drop up to 1000 Pa. 

The unit casing contains a robust flanged mounting frame for duct installation. The modular VAV control device consists of an aluminium measurement probe, polyurethane measurement impulse tubes, an airflow transmitter, a modular control unit and an actuator. The measurement probe is a special design cross. It is a multi-point averaging flow sensor for accurate airflow readings. The measurement impulse tubes connect the measurement probe with the airflow transmitter.
