L-Series
Overview
Designed for bigger cooling demands

L‑Series Axial EC Fans are designed to meet today’s growing cooling challenges with fewer, but larger, modular fans. Higher airflow, lower noise, and simpler maintenance. In short, more uptime, less hassle.

Fewer fans mean fewer motors, fewer connections, and fewer points of failure. With diameters up to 1,800 mm and optimized blade geometry, L-Series fans move more air per revolution, cutting turbulence and energy consumption.

Grid

Aerodynamically optimized design for minimal energy waste. C3-level corrosion-resistant paint grade as standard.

Blade

Utilizing the width of the modular impeller range to achieve the maximum performance.

Airflow shape
Sickle blade

Hub

Perfectly paired to maximize blades’ full airflow potential.

Internal rotor motor

Robust direct driven powerful PM internal rotor motor mounted on the suction side for maximum performance and durability.

External drive

Out-of-airflow, ready to provide the additional power needed for environments like cooling towers.

Brackets

Harmonized design, engineered to minimize airflow impact.

Housing

Specially designed bellmouth heavy duty inlet and short diffuser providing superior flow and performance. Available both as square or round plate.

Designed for harsh environments, the L‑Series leverages Multi‑Wing’s internal rotor motor for superior heat dissipation, lower motor temperatures, and longer bearing life. With power outputs up to 200Nm/30kW, it’s ready for high‑power applications.

Modular construction makes servicing easy, just as upgradable components enhance corrosion protection and eco‑friendliness.
