W4D300-DT04-09 ebmpapst 230/400/460V 300mm AC Axial Fan

Description

The ebmpapst W4D300-DT04-09 is a high-performance 230/400/460 V industrial AC axial fan with an impeller size of 300 mm, purpose-built to deliver elite-level thermal cooling in high-resistance airflow paths. This unit features a heavy-duty M4D068-DF external rotor motor capable of sustaining power inputs ranging from 65 W to 100 W to drive its specialized 5-blade PP plastic impeller at speeds up to 1600 RPM. Engineered specifically for air displacement in medium-scale cooling systems, it utilizes a 300 mm diameter housing to provide balanced pressure and airflow for mission-critical hardware. The mechanical design relies on precision maintenance-free ball bearings and a galvanized sheet steel frame coated with black plastic (RAL 9005) to ensure reliable continuous operation across an ambient temperature range of -25 °C to 70 °C. Featuring a versatile 3-phase electrical interface supporting Delta (230 VAC) or Star (400/460 VAC) wiring, this fan is a critical component for condenser cooling, industrial refrigeration, and power electronics thermal management where long-term durability and high aerodynamic efficiency are mandatory.
