Unit Price
The Ebmpapst 4656EZ is a compact cross‑flow fan engineered for high performance and low energy consumption in industrial applications. With a 465 mm housing diameter and 150 mm depth, it fits easily into tight spaces. The fan delivers 2 800 m³/h (≈ 49 CFM) airflow and 200 Pa (≈ 0.8 inH₂O) static pressure, providing efficient air distribution for HVAC, cooling and ventilation systems. Its EC‑inside motor operates at 90 % energy efficiency and is compatible with 50 Hz/60 Hz mains frequencies. Insulation class F and IP54 protection guard against dust and water splashes. The aerodynamic “Silent‑Blade” impeller reduces noise while maintaining high efficiency. Low maintenance requirements and a long service life help lower total cost of ownership.
