Description
The ebmpapst W4D500-GM03-01/F02 is a high-performance three-phase AC axial fan featuring HyBlade sickled blades (S series) with a full square nozzle, driven by an M4D110-GF motor. Engineered for a nominal voltage of 400 VAC at 50 / 60 Hz, it delivers multi-frequency performance under max. load conditions: operating at 50 Hz in delta connection (Δ), it provides a speed of 1,390 min⁻¹, drawing a power input of 720 W, a current draw of 1.41 A, a starting current of 6.5 A, and a max. back pressure of 140 Pa; in star connection (Y), it provides a speed of 1,180 min⁻¹, drawing a power input of 550 W, a current draw of 0.95 A, and a max. back pressure of 100 Pa. Operating at 60 Hz in delta connection (Δ), it achieves a speed of 1,590 min⁻¹ (1,640 min⁻¹ at 460 VAC), drawing a power input of 1,020 W (1,060 W at 460 VAC), a current draw of 1.7 A (1.64 A at 460 VAC), and a max. back pressure of 130 Pa (138 Pa at 460 VAC). Constructed with dimensions of 656 x 656 x 180 mm, a 500 mm impeller size, a mass of 16.7 kg, black-coated rotor surface, PP plastic terminal box, press-fitted sheet steel blank blades sprayed with PP plastic, pre-galvanized sheet steel wall ring coated in black plastic (RAL 9005), and a steel guard grille coated in black plastic (RAL 9005) with 5 blades, this unit ensures robust industrial operation. It features ball bearings, counter-clockwise direction of rotation seen on the rotor, “V” direction of air flow, IP54 degree of protection, insulation class “F”, F4-1 humidity class, and continuous S1 duty mode with shaft horizontal or rotor on bottom mounting position. It includes rotor-side condensate discharge holes, electrical leads via a terminal box with axial cable exit, brought-out thermal overload protector (TOP), touch current <= 3.5 mA according to IEC 60990, protection class I (if protective earth is connected by customer), and conforms to EN 61800-5-1 and CE standards with GOST, VDE, and CCC approvals. It operates reliably across an ambient temperature range of -40 to +65 °C (up to +50 / +60 °C at 60 Hz), with a transport and storage temperature range of -40 to +80 °C. ErP directive data at optimum efficiency point indicates an overall efficiency η_es of 33.4%, efficiency grade N of 40.6%, power input P_e of 0.73 kW, air flow q_v of 5,860 m³/h, pressure increase p_fs of 151 Pa, and speed n of 1,385 min⁻¹ under category A static efficiency.
