Description
The ebmpapst D4E133-AA01-44 is a high-performance 230VAC single-phase AC Centrifugal Blower with a dual-inlet design, including a housing (flange) and an impeller diameter of 133 mm. Specifically engineered for mission-critical cooling in HVAC systems and industrial ventilation, this unit features overall dimensions of 230 x 180 x 170.5 mm. Driven by the M4E068-BF external rotor motor with maintenance-free ball bearings, it operates on a 230 VAC supply, delivering a Power Consumption of 66 W (50 Hz) / 80 W (60 Hz) and a Current Draw of 0.29 A / 0.35 A at a rated speed of 1200 RPM under free air conditions. Requiring a 2.0 µF / 400 VDB capacitor for operation, this unit features a motor mounted with brackets on one side for vibration damping and a rugged galvanized sheet steel housing. Optimized for continuous S1 environments, it ensures superior thermal management with IP44 protection and an extended service life at the end.
