Description
The ebmpapst S4E300-AR26-87 is a high-performance industrial AC axial fan with a nominal voltage of 230 VAC and an impeller size of 300 mm, specifically engineered for reliable thermal management in commercial refrigeration and HVAC systems. Driven by a robust single-phase M4E068-CF external rotor motor with a power consumption of 70 W at 50 Hz and 95 W at 60 Hz, this unit features a heavy-duty ball bearing system with anti-freezing grease designed for long-term mechanical stability and continuous S1 duty. Its aerodynamic design with 5 black-coated sheet steel blades delivers efficient air circulation in a “V” direction (exhaust over struts), reaching speeds up to 1570 RPM at 60 Hz. Constructed with a phosphated steel guard grille coated in black plastic and an ABS plastic terminal box, this 3.1 kg fan provides a dependable and weather-resistant cooling solution with IP44 protection and F1-2 humidity class for industrial condensers, heat pumps, and cold storage infrastructure at the end.
