D2D146-AF02-14 ebmpapst 230/400V AC Centrifugal Blower

Description

The ebmpapst D2D146-AF02-14 is a high-performance 3-phase AC Dual Inlet Centrifugal Blower with a 146 mm impeller diameter, designed for high-static pressure industrial cooling and ventilation. Powered by the M2D068-EC (Size 68) external rotor motor, this unit offers exceptional electrical flexibility, supporting 230 VAC Delta (Δ) or 400 VAC Star (Y) wiring configurations. It delivers a maximum air pressure of 200 Pa at 50 Hz (2100 RPM) and up to 240 Pa at 60 Hz (2200 RPM). The blower is constructed with a galvanized sheet steel scroll housing and a forward-curved impeller, ensuring durability and corrosion resistance. With a power input of 345 W (50 Hz) and 410 W (60 Hz), this 4.3 kg unit provides reliable S1 continuous-duty performance. Featuring an IP00 protection rating and H0+ environmental class, the D2D146-AF02-14 is an ideal air-moving solution for integrated industrial machinery, laboratory equipment, and 230/400V 3-phase HVAC infrastructure.

Application
The ebmpapst D2D146-AF02-14 is a robust air-moving component for laboratory fume hoods, localized industrial process cooling, and integrated ventilation systems in machinery. Its 146 mm forward-curved galvanized impeller is optimized to maintain high static pressure (200-240 Pa), making it ideal for forcing air through dense heat exchangers or ducting. The dual-voltage 230/400V 3-phase M2D068-EC motor provides versatile electrical integration for global industrial power grids. With its compact 4.3 kg galvanized steel construction and S1 continuous-duty rating, the D2D146 provides high-velocity, reliable cooling for mission-critical industrial infrastructure where precise thermal management is required in dry environmental conditions.
