E4809-770-050-A by Okuma

The Okuma E4809-770-050-A is an advanced cooling solution from the E4809 CNC Boards series, engineered by Okuma for industrial automation applications. This single phase axial flow fan is optimized for a voltage range of 200–230V, ensuring compatibility with a broad spectrum of CNC control systems. With compact dimensions of 120 x 120 x 38 mm, the unit integrates smoothly into control panels without occupying excessive space. Its lightweight construction at approx. 700 g minimizes load on mounting brackets while delivering reliable airflow. Designed for demanding environments, the E4809-770-050-A balances performance, efficiency, and durability.

The technical proficiency of this fan is evident in its dual-speed operation, achieving rotational speeds of 2700 rpm at 50 Hz and 3250 rpm at 60 Hz. It draws 0.27 A at 50 Hz and 0.24 A at 60 Hz, maintaining energy-efficient operation under varying electrical conditions. Power consumption remains low at 33 W/35 W, aiding in system power budgeting while providing robust thermal management. The fan employs ball bearing technology for extended service life and reduced maintenance intervals. Its Insulation Class B (130°C) rating safeguards internal windings against elevated temperatures, ensuring longevity under heavy-duty operation.

Operationally, the unit offers IP44 enclosure protection, shielding critical electronics from dust ingress and dripping water in standard industrial environments. Noise emissions are kept below 40 dB(A), preserving a quieter workspace and minimizing acoustic disturbance near control cabinets. The fan’s operating temperature range of –10°C to +60°C ensures consistent performance across diverse ambient conditions. Secure panel mount installation simplifies integration into existing enclosures, providing fast replacement cycles and minimal downtime. This combination of low noise, robust protection, and ease of installation makes it an ideal choice for continuous-duty applications.

Integration of the E4809-770-050-A into CNC control systems is streamlined through its industry-standard 200–230V power interface and compact 120×120×38 mm footprint. Its compatibility with single-phase supplies and straightforward panel mount design accelerates commissioning on new or retrofit installations. The fan’s balance of reliable airflow, thermal endurance, and compact size supports applications in machine tools, industrial robots, and automated production lines. With Okuma quality and precision, this fan board enhances system uptime and thermal stability, driving productivity gains in industrial automation settings.
