COPRA™ EC fans stand out; combining system efficiency and power density within a compact design for the best overall performance. The combined EC motor, fan impeller, and integrated controller creates a reliable air flow necessary to commercial HVAC and Data Center applications.
Conventional plug fan:
The problem with conventional plug fans is impeller obstruction. The rotor of the external-rotor motor causes airflow turbulence in the impeller. This in turn reduces efficiency.
COPRA™ FANS:
With COPRA, we have succeeded in developing a system with internal-rotor motor that does not suffer from annoying airflow turbulence. It represents the ideal symbiosis with the new motor form factor. The short PM/EC motor is the benchmark here and achieves an efficiency class of up to IE6.


SWAP ordinary plug fans for COPRA™ EC fans! Unleash maximum airflow with a unique blend of engineering and performance, thanks to powerful backward- curved aluminum impeller blades.
Efficiency maximized, space minimized. Say oodbye to airflow obstactles with our sleek internal rotor motor, as aerodynamic impeller designs ensure high power at all speeds.
The perfect fit for data centers and tight HVAC spots! Designed to squeeze into even the tightest spots, making installation a breeze, down to the last centimeter.
With reduced weight and size, COPRA™ system fits multiple wall configurations in locations such as office buildings, hospitals, libraries and other commercial building spaces.
COPRA™ easy installation fits new or retrofit projects. The cooling system is compliant with IT industry-wide specifications. Energy and consumption costs are reduced to the lowest feasible level.
COPRA™ effectiveness exceeds traditional motors in every situation with its system efficiency at part load compared to all other conventional ec motor technology.
Unleash aerodynamic efficiency in an ultra-compact powerhouse! COPRA™ redefines the game with its short axial length, delivering unmatched efficiency for tight installations.

COPRA™ fans come in two cinfigurations and with a wide range of variants to best suit your equipment needs.

The chart shows an overview of sizes 250 mm to 710 mm with 1.3, 4.5 and 8 kW motor power at the maximum speed of the respective size. The ranges with the best overall static fan efficiencies (operating range with best efficiency) are highlighted.


The new COPRA™ fans maximize efficiency while minimizing required space in your system. Their short motor do not obstruct airflow, while the newly developed aerodynamic impeller design maximizes efficiency at both full and reduced speeds. Perfect for simple plug-&-play installation in new HVAC systems as well as for the modernization of existing systems, COPRA™ fans can deliver significant cost savings.



COPRA™ fans are ideally suited to multiple wall configurations in the form of several fans arranged next to and above each other. COPRA™ fans are the best fit for multiple wall configurations not only because of their compactness in axial length, but also because of their smallest possible diameters with high airflows.
