Purpose
RF, RFE and RFG are compact fans for small extract and supply systems in round ducts of Ø 100–150 mm, including installation above a false ceiling.
RF
A compact centrifugal fan with circular spigots in a galvanised steel casing (IP44). The single-phase three-step motor is switched with a step switch.
RFE and RFG
Mixed-flow fans with an integrated guide vane in a black polypropylene casing (IP54). RFE has a three-step single-phase motor, RFG an electronically commutated (EC) DC motor. Reduction flanges allow connection to smaller ducts. The manufacturer introduced both as new products in its 2009 and 2017 brochures.
For higher airflow, see RS / RK / ERM / DRM.
