COPRA™ EC Plenum Fan
Short, compact fan module with static system efficiency up to 71%. Aluminium wheel with 3D airfoil blades. Compact EC internal rotor motor in efficiency class IE6 with integrated control electronics.
Product Overview
COPRA is a high-performance fan solution designed for critical environments, offering quick availability, proven reliability, and strong lifecycle performance. Manufactured in the USA with short lead times and stocked options, it supports urgent project needs within cleanrooms, AHUs, CHVAC systems, and auxiliary cooling for data centres. Engineered for stable airflow, energy-efficient operation, and low maintenance, COPRA delivers robust performance for new installations and an easy path for retrofitting. With the upcoming COPRA Hybrid, customers will also gain access to next-generation efficiency and long-term sustainability improvements.
Replace standard plug fans with COPRA™ EC fans! Unleash maximum airflow with a unique combination of engineering and performance, thanks to powerful backward-curved aluminium blades.
Efficiency maximised, space minimised. Say goodbye to airflow obstructions with our sleek internal rotor motor, where aerodynamic impeller designs ensure high performance at all speeds.
The perfect solution for data centres and compact HVAC spaces! Designed to fit even in the tightest spaces, making installation easy, down to the very last centimetre.
The perfect plug fan for fan arrays
COPRA™ fans are ideal for multiple wall configurations in the form of several fans placed next to and above each other.
COPRA™ fans are the best choice for multiple wall configurations, not only because of their compact axial length, but also because of their smallest possible diameter with high airflow.
Retrofit: Replacing fans with COPRA™ fans is worth fitting in
Lower energy costs | Less maintenance | Reduced emissions
The new COPRA™ fans maximize efficiency while minimizing the space required in your system. Their short motor does not block airflow, while the newly developed aerodynamic impeller design maximizes efficiency both at full and reduced speed. Perfect for simple plug-&-play installation in new HVAC systems as well as for modernizing existing systems, COPRA™ fans can deliver significant cost savings.
