Now even more air at high pressure.
9 November 2022

Completely redeveloped – the aluminum high-pressure series RHDA . An even more powerful series developed to impress with its efficiency and compact design. Flow simulations and load tests were used to optimize and perfectly match the impeller and housing.


The series has a direct drive and works with a frequency converter. This speeds up the motor to a maximum of 140 Hz. This produces even more air at a higher pressure.


Curious about this series? Then take a look at our
