ACmaxx / GreenTech EC-Compact fans DC centrifugal fan overview DC centrifugal fans DC tangential fans DC centrifugal fans and blowers

Technical information Product line Voltage range Our centrifugal product line includes fans for every application. Whether Many of our DC fans can be operated on voltages that are up to 50% as free-running impellers with a diameter between 97 mm and 225 mm lower and 25% higher than their nominal voltage (see Voltage range in the or as assemblies in a ready-to-install, compact housing with inlet nozzle technical tables). This enables the air performance to be adapted to the with an edge length between 51 mm and 270 mm. Of course, all models cooling requirements and allows the noise to be...
