D4E146-LV19-14 ebmpapst 230V 146mm AC Centrifugal Fan

Description

The ebmpapst D4E146-LV19-14 is a highly efficient 1-phase AC Dual Inlet Centrifugal Fan featuring a 146 mm PA plastic impeller and a robust PP plastic housing. Driven by the M4E068-CF external rotor motor with anti-vibration mounting on both sides, this unit is designed for versatile air displacement with 5 integrated speed steps. Operating at a nominal voltage of 230 VAC, it delivers a rated speed of 780 RPM (50 Hz) with a power input of 65 W, ensuring whisper-quiet and stable performance. This 2.5 kg module features an integrated terminal box with a pre-connected 2 µF capacitor and a convenient plug system for electrical connection. With IP44 protection, Insulation Class F, and an internal thermal overload protector, the D4E146-LV19-14 provides a reliable, vibration-damped cooling solution for residential ventilation, air purifiers, and light industrial HVAC systems.

Application
The ebmpapst D4E146-LV19-14 is specifically engineered for noise-sensitive air-moving applications such as decentralized home ventilation units, laboratory fume hoods, and high-end air filtration systems. Its 146 mm PA plastic impeller and dual-vibration-damped motor suspension significantly reduce structural resonance and mechanical noise during operation. The 5-speed step design allows for precise control of airflow, reaching up to 580 m³/h (341.4 CFM) to match specific environmental demands. Equipped with an integrated capacitor in the PP terminal box and a plug-and-play connection, this 2.5 kg centrifugal blower ensures rapid installation and long-term, maintenance-free reliability in modern 230V AC climate control infrastructures.
