Circular air diffuser RFD-SIRIUS

rectangularceilinginduction

RFD-SIRIUS is used in ventilation and air conditioning systems for the demand-based volume flow control and as an air terminal device. RFD nominal sizes: 160, 200, 250, 315 and 400 SIRIUS nominal sizes: 125, 160, 200 and 250 For supply air Flush ceiling installation, with discharge nozzle also suspended installation Control input signal via MP bus, LonWorks FTT-10A, Modbus RTU, or analogue signal Integral noise insulation element High induction results in a rapid reduction of the temperature difference and airflow velocity Ideal for comfort zones Exposed diffuser face available in RAL CLASSIC colours RFD-SIRIUS combines the functions of a volume flow controller, sound attenuator, plenum box and air terminal device in one unit. The differential pressure is measured with integral measuring tubes and transmitted to the controller. An integral linear actuator adjusts the damper blade such that the required setpoint value is achieved. The construction of the diffuser ensures that sound is effectively absorbed, which results in low sound power levels.
