The W1G180-AB11-32 from EBM-Papst is a compact EC diagonal fan with dimensions of 220×70 mm and a housing made of die-cast, black-coated aluminium. It operates on 48 V DC and delivers an airflow of 620 m³/h at 3,200 rpm. Thanks to its EC (electronically commutated) motor, it combines high performance with energy-efficient operation.
The fan is ideal for dense installations where space is limited but airflow requirements are high – for example, in server cabinets, industrial electronics, and compact ventilation units. The 0–10 V DC/PWM control input makes it easy to integrate speed control into existing systems.
