Design
OPTIMA-R-FC...BM is manufactured from galvanized steel sheet. The product consists of a casing, a duct connection
with a rubber gasket, a damper blade with a rubber gasket and a modular VAV control device. OPTIMA-RI-FC...BM is
equipped by an insulation for sound reduction. The insulation is a 19 mm thick closed cell foam mat, protected by
galvanized steel sheet. The modular VAV control device consists of an aluminium measurement probe, polyurethane
measurement impulse tubes, an air flow 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 air flow readings. The measurement
impulse tubes connect the measurement probe with the air flow transmitter.
