RVK A1 125 mm is the 125 mm variant of the classic RVK inline duct fan offered by Global Air Supplies. It uses the A1 motor curve and a backward-curved, motorised impeller in a robust fibreglass and polypropylene housing. The unit is designed for extractor or intake use and can be installed in any orientation; a mounting bracket is supplied. It runs from mains power and is speed-controllable via an external controller. Safety features include integrated thermal protection and an IP44-rated terminal box. The maximum free-airflow is 165 m³/h according to the 2024 G.A.S catalogue, with the 125 L1 option rated higher if more output is required. The RVK range is maintenance-free, quiet for its size, and carries a two-year warranty.
