GRONBACH - Manufacturer, supplier of fan wheels, impellers & blowers

Main page » Technologies » Synthetics injection moulding technology » Fan wheels, blowers and turbines

In the fluid dynamics laboratory of our Wasserburg competence centre, we design new fan wheels, fan impellers and turbines and optimise existing systems for performance, energy efficiency and noise emissions. Our expertise is also defined by the optimized development of complete blower systems.

The production of fan wheels, impellers and turbines takes place in Wasserburg (Made in Germany) and in Michalovce/Slovakia. Thanks to our decades of experience and our technologies, we achieve outstanding results in unbalance, axial and radial runout.
The advantages of our optimized blower systems lie in the improvement of flow efficiency and noise development, production optimization, significant reduction of costs compared to metal fans and optionally in the adaptability to existing systems.

Optimized blower systems custom-made

Our excellent infrastructure and many years of experience enable us to develop complete blower systems according to individual customer specifications. Together with you, we do not develop anything ready-made, because only in this way we can ensure that the combination of fan wheel + motor + electronics + housing + air ducting is always optimised for the application device.

Your benefits

Development of optimized complete systems
Increased efficiency due to adapted fan geometry and air ducting
Improved flow characteristics
Noise optimisation
Cost optimization through optimized sizes
Motor procurement and adaptation, depending on requirements
Flexibly adapted electronics for different motor types, integrated or separated
