N43-35513 400V GKHM 355-CIE.112.5FA EC Plug Fan Module IE Gen 3

The Rosenberg GKHM series EC plug fan combines high performance, ultra‑low noise, and energy efficiency in a compact package. Designed for low to medium pressure applications, this fan is ideal for air handling units, HVAC systems, and OEM installations seeking a reliable, high efficiency solution.

Key Features & Benefits

High Efficiency Motor

Equipped with the latest generation 3 EC motor technology the N43-35513 GKHM series delivers IE5 efficiency levels. It dynamically adjusts to power demand across the operating range, offering up to 30 % more power output than previous generations.

Compact, Lightweight Design

The lightweight impeller is made from long‑fiber, UV stabilised polypropylene (1.22 kg/m²), with a 7-blade aerofoil profile. This, along with a narrow radial diffuser, maximises static regain and airflow while keeping noise and vibration low.

Low Noise & Smooth Running

The backward curved impeller generates pressure within its envelope, reducing the need for bulky scroll housings. Combined with careful CFD optimised blade design and minimal motor airflow interference, this fan delivers quieter operation and smooth, efficient airflow.

Robust Motor & Environmental Ratings

• IP54 protection for clean, dry air environments
• Protection class F insulation
• Temperature range: –25 °C to +40 °C

Flexible Speed Control

Speed control can be implemented via electronic (triac) or transformer techniques, allowing adaptable integration into a range of control systems.
