Functional description
RFD-SIRIUS combines the functions of a volume flow controller, sound attenuator, plenum box and air terminal device in one unit. To determine the current actual volume flow rate, the differential pressure is measured using the integrated measuring tubes and transmitted to the controller. Depending on the desired setpoint value, the volume flow control unit is adjusted with an integrated linear actuator. The construction of the diffuser ensures that sound is effectively absorbed, which results in low sound power levels.
Nominal sizes RFD | 160, 200, 250, 315, 400 mm |
Nominal sizes SIRIUS | 125, 160, 200, 250 mm |
Volume flow rate | 4.7 – 171.4 l/s or 17 – 617 m³/h |
Supply air to room air temperature difference | -12 to +10 K |
Quick sizing tables provide a good overview of the volume flow rates and corresponding sound power levels and differential pressures.
The minimum volume flow rates apply to a supply air temperature difference of -6 K.
The maximum volume flow rates apply to a sound power level of approx. 50 dB (A).

RFD-SIRIUS is an air terminal device combined with a VAV terminal unit. The ceiling diffuser with a square or circular diffuser face is preferably used as a supply air diffuser for comfort zones. The fixed air control blades allow for horizontal swirling supply air discharge creating high induction levels. The diffuser is suitable for installation into all types of suspended ceilings. The diffuser is fixed with a central fixing screw to the cross bar (no tools required); the cross bar is inserted into the SIRIUS plenum box (no tools required) and held in place with magnets. The SIRIUS plenum box is fitted with two spigots, one for connection to the ductwork and another one for connection of the diffuser face. The SIRIUS plenum box contains two cylinders, one fitted inside the other; one of the cylinders is perforated. The perforated cylinder is moved along a toothed bar upon control input from the volume flow controller, and the free area changes as a consequence. A fleece covering the perforated cylinder acts as an equalising element. This special construction feature allows for omitting any additional sound attenuator.

Application
Installation and commissioning
Upstream conditions
The volume flow rate accuracy ΔV applies to a straight upstream section of the duct. Bends, junctions or a narrowing or widening of the duct cause turbulence that may affect measurement. Duct connections, e.g. branches off the main duct, must comply with EN 1505. Some installation situations require straight duct sections upstream.
