The D4E146-LV55-01 from EBM-Papst is a compact centrifugal fan with forward-curved blades and double-sided intake, designed for demanding ventilation and air handling applications. The fan delivers up to 565 m³/h at free air flow and is powered by a single-phase 230 V AC motor with five speed settings. The housing is made of robust PP plastic with flange mounting and IP44 protection.
The fan is ideal for applications such as air handling units, heat recovery, and industrial ventilation where a compact size and flexible installation are important. Optional mounting position and a low weight of 2.5 kg make it easy to integrate into existing systems.
